1. Introduction
The Lantronix SESPM1040-541-LT-xx Switch is a Layer 2 managed switch with (4) 10/100/1000Base-T PoE++
(IEEE 802.3bt) ports and (1) combination 10/100/1000Base-T RJ-45 or 100/1000Base-X SFP uplink port
(additional optional ports available), that is ideal for use in security and surveillance, PoE lighting, digital signage
and many other applications.
The SESPM1040-541-LT-xx switch is self-enclosed in an outdoor NEMA 4X/IP 66 rated enclosure with 6KV surge
protection on the AC line to protect against surges in power, built in surge protection on PoE and data ports for
lightning protection, and additional fuse protection on PoE and included data port for external circuit cross
protection against unintentional intrusion from outside power lines. It can be mounted on a wall or side of a
building, or optional brackets are available for mounting on a pole.
The switch is available in multiple configurations: as either an AC- or DC-powered power source (PSE) providing
up to 90W on individual ports*(not to exceed 180W total on the AC powered unit or 240W on DC powered
unit), or as a PoE-powered device (PD) which is also a PSE providing up to 80W of total PoE power. The PD
version requires PoE power from an IEEE 802.3 bt Type 4 Class 8 compliant PSE, or it can receive power over
copper cable running parallel to a fiber optic cable for data (i.e., composite cable). (*Specific port configuration
may apply; see Port Configuration on page 28.) The -PD version includes a 12V Aux port which can be used to
provide auxiliary power to a PC, lighting or other accessories.
On all versions, a second 10/10/1000Base-T RJ-45 maintenance or 1000Base-X SFP uplink port can be activated
by installing an optional Combo Port Module (sold separately). Alternatively, an optional Passive PoE Combo
Port Module can be added to provide 24VDC power to non-standard PoE powered devices such as wireless
radios, eliminating the need for an additional external power source for those devices. An optional Digital
Input/Output Module with four optical isolators configurable as either inputs or outputs can provide
connections for alarms, event notifications, or other customer designated items.
All versions are also equipped with Near Field Communication (NFC) to allow simple, repeatable switch
configuration with a user-friendly app on a mobile device prior to connecting or powering up the switch. And on
all versions Bluetooth Low Energy (BLE) allows remote access to alarm information or to read or change
equipment settings without requiring physical access using inconvenient ladders or scissor lift rental.
The switch also has integrated management software for setup, monitoring, and control of connected devices.

Port Configuration
Ports 1-4 are 10/100/1000Base-T PoE++ PSE Ports.
Port 5 is a combo 10/100/1000Base-T or a 100/1000Base-X uplink port. On the AC and DC version, it can either
be used as a copper or fiber port. However, on the PD version, it is normally used for PoE power input, in which
case the SFP option is not available unless you are using fiber cable running in parallel to a copper cable as the
power input, then port 5 can be used as a fiber port (or copper) instead of using it exclusively as the PoE power
input port.
Port 6 becomes available when you add an optional Port 6 module (e.g., the optional Additional Combo Port
Module or the optional 24V Passive PoE Module providing 24VDC power). The optional Additional Combo Port
Module allows you to activate a second combo 10/100/1000Base-T maintenance port or second 1000Base-X
uplink port. Alternatively, port 6 can be used for the optional 24V Passive PoE Module. (Because they share the
same port, the Additional Combo Port Module providing the 10/100/1000Base-T maintenance port or second
1000Base-X uplink port and the 24V Passive PoE Module providing 24VDC power cannot be used at the same
time.)
Note: If using more than one 90W port, alternate ports (i.e., avoid adjacent 90W ports). Use ports 1 and 3 or
ports 2 and 4. Exception: using ports 2 and 3 for 90W is allowed. See the related CLI or Web UI section of this
manual for PoE priority setting and PoE port power shutdown information.
Console Port
If you have physical access to the switch, a console cable can be plugged into the
Console port in order to configure the switch. The default settings are:
Bits per second (data rate) = 115,200
Data bits (# of bits) = 8
Parity = None
Stop bits (# of stop bits) =1
Flow control = None

2. Software Configuration
Software Components
The SESPM1040-541-LT-xx interfaces with the following software elements:
•Web UI on a desktop or laptop
•CLI
•Smartphone or tablet via NFC
•Smartphone or tablet via BLE
Last Gasp
In the event of power failure, the switch has a Last Gasp feature that allows the switch to save enough power to
send a trap notification of the power failure. The 'Last Gasp' feature provides 10W for 5mS; however, PoE power
is not protected on failure.
Automatic Operation
The SESPM1040-541-LT-xx switch performs these operations automatically:
•Shut down the switch if an over temperature condition is detected. If the temperature within the enclosure
exceeds 70°C the switch will power off automatically.
•Shut off power to a port in case of a port being over powered. If PD power exceeds power available, ports
will shut down according to priority settings (see the poe priority command on page 115 or see Switch > PoE
Management > PoE Status on page 168.
•Load NFC configuration at boot up. An option exists to disable this feature. See Switch > Security >
Management > NFC on page 187.
•Update PoE firmware at boot up. This can also be done via CLI and Web UI. The switch will only update PSE
firmware automatically if it can correctly determine the current running version. Otherwise, the message
"Unable to determine running PSE firmware version, exiting PSE firmware update" displays.

33773 Rev. F https://www.lantronix.com/ Page 10 of 228
PoE Services
The SESPM1040-541-LT-xx PoE is controlled by a set of services that are each able to disable PoE on one or all
PoE ports. You can configure and enable or disable the following services:
•PoE Auto Power Reset (APR) services
•PoE Schedule services
•Port Power Monitor services
PoE Services that cannot be disabled are:
•PSU Temperature Monitor services
•Total Power Monitor services
Each of the services may set a port to off. If that happens, PoE is shut off for that particular port. Power off
events generate a trap (if traps are enabled) and a syslog message with information about what caused power to
be shut off.
If a service is disabled, it does not affect PoE on that port. By default, APR and Scheduler are disabled as they
require user configuration.
The PoE Service Status page on the Web UI and the service status CLI command show poe service are
intended to be a quick overview of the services and should show which service shutdown a particular port.
The syslog message contains the date/time of the event as well as relevant details (PSU Temperature at the time
of an over temperature event, for example).
PoE Automatic Power Reset (APR) Services
PoE Automatic Power Reset (APR) monitors a device and can power cycle the PoE port if connectivity is lost. To
determine connectivity, ping is used. It is expected, but not required, that the ping frames are directed at the
device attached to the PoE port.
To monitor a device, APR has several phases it moves through.
•Discovery Phase 1 is the first phase. The purpose of this phase is to allow the PoE attached device time
to boot and possibly acquire an IP address via DHCP. To allow the device time to boot, in this phase ping
failures are not counted. Pings are sent every Interval Time seconds. If at any point during Discovery
Phase 1 a ping is successful, APR moves to the Monitor phase. Discovery Phase 1 lasts 10 minutes. If the
Failure Action is Log and Trap, a syslog message and trap are generated, and APR moves to Discovery
Phase 2. If the Failure Action is Reset, Log and Trap, PoE is reset, a syslog message and trap are
generated, and APR moves to Discovery Phase 2.
•Discovery Phase 2 is similar to Discovery Phase 1. Phase 2 lasts 10 minutes, does not count ping failures.
Pings are sent every Interval Time seconds. On a successful ping, APR moves to the Monitor Phase.
Discovery Phase 2 also lasts for 10 minutes. If the end of Discovery Phase 2 is reached without a
successful ping frame, APR moves to the Failure phase and user intervention is required. If the Failure
Action is Log and Trap, a syslog message and trap are generated. If the Failure Action is Reset, Log and
Trap, PoE is disabled on the port, a syslog message and trap are generated.
•Monitor phase indicates that APR has successfully discovered its attached device and is now being
monitored. Pings are sent every Interval Time seconds. Each successful ping resets the ping failure
counter. If the ping failure counter reaches the Retry Count setting, an APR Failure event occurs. If the
Failure Action is Log and Trap, a syslog message and trap are generated, and APR moves to Discovery
Phase 1. If the Failure Action is Reset, Log and Trap, PoE is reset, a syslog message and trap are
generated, and APR moves to Discovery Phase 1.

Lantronix SESPM1040-541-LT-xx Operation Guide
33773 Rev. F https://www.lantronix.com/ Page 11 of 228
•Failure phase indicates that APR was unable to contact the attached device. APR disables itself and user
intervention is required to restart APR. If the Failure Action is Log and Trap, power remains on for this
port. If the Failure Action is Reset, Log and Trap, power is shut off to the port.
To configure APR from the Web UI:
•To enable APR from the Web UI, set Ping Check to Enabled.
•To set the IP address APR should monitor, fill in Ping IP address.
•To set the interval between pings in Discovery Phase 1, Discovery Phase 2 and Monitor, modify the
Interval Time field.
•To set how many consecutive missed pings initiates an APR failure event, modify Retry Count.
•To set the action of Failure Events, use the Failure Action pulldown - if Log and Trap is selected, APR will
not shut off PoE at any time.
To configure APR from the CLI:
•To enable APR on Port 1:
configure terminal
interface GigabitEthernet 1/1
poe apr ping-check enable
•To disable APR on Port 1:
configure terminal
interface GigabitEthernet 1/1
poe apr ping-check disable
•To set the Ping IP address on Port 1 to 10.10.10.10:
configure terminal
interface GigabitEthernet 1/1
poe apr ip 10.10.10.10
•To set the ping interval time on Port 1 to 45 seconds:
configure terminal
interface GigabitEthernet 1/1
poe apr interval 45
•To set the number of missed pings in the Monitor phase before initiating a failure on Port 1 to 4:
configure terminal
interface GigabitEthernet 1/1
poe apr retries 4
•To set the APR Failure Action on Port 1 to Log and Trap:
configure terminal
interface GigabitEthernet 1/1
poe apr failure LogTrap
Current APR status is on the PoE Service Status page in the Web UI or from the CLI:
show poe service
If APR is disabled by another PoE service, its status would be:
Off – Disabled by other PoE service
If APR has been disabled by the user, its status would be:
Off

Lantronix SESPM1040-541-LT-xx Operation Guide
33773 Rev. F https://www.lantronix.com/ Page 12 of 228
If APR is in either of the Discovery Phases, its status would be like this (Phase 2 for 222 seconds):
Discovery Phase 2 - Duration: 222s
If APR is in the Monitor Phase, the status shows how long it has been in this phase, the current consecutive
failure count and how many failures have occurred since enabling APR, its status would be:
Monitoring - Duration: 5000s Consecutive Failures: 0 Failure Events: 2
If APR failed Discovery Phase 2 and Reset, Log and Trap is the Failure action, its status would be:
Port Disabled - APR Failure - Discovery failed after 20 minutes, please verify
configuration
If a port is resetting, these are the possible statuses:
Resetting after Discovery Phase 1 timeout
Resetting after Monitor failure - Failure Events: 3
PoE Schedule Services
PoE Schedule allows you to create a schedule that can be applied to a PoE Port. Operations that can be done to
a port are power on, power off, and reset (power off followed quickly by a power on).
Currently, schedules are weekly and recurring. When a schedule is applied to a port, the scheduler will
determine the current expected PoE state for the port and set it.
For example, the schedule to be applied consists of the following events:
Event
Day
Event Time
Power Off
Monday
21:00
Power On
Tuesday
15:00
Power Off
Tuesday
22:00
Power On
Wednesday
17:00
•If the schedule were applied at 08:00 on Tuesday, the port would be powered off and then at 15:00 on
Tuesday (the next event in the schedule), the port would be powered on and then proceed through the
schedule.
•If the schedule were applied at 17:00 on Tuesday, the port would be powered on and then at 22:00 on
Tuesday the port would be powered off and then proceed through the schedule.
•If the schedule were applied at 12:00 on Saturday, the port would be powered on and then at 21:00 on
Monday it would be powered off and then proceed through the schedule.
Schedule Notes:
•By default, there are 16 empty profiles (schedules) - no more profiles can be created.
•In a profile, at a given time, there can be only one event.
•A profile can be applied to multiple ports.
•A port can only have one profile applied at a time.
•Different profiles can have an event at a specific time (Port 1 could be powered on at 12:00 on Monday
and Port 2 could be powered off at 12:00 on Monday as well by using two different profiles).

Lantronix SESPM1040-541-LT-xx Operation Guide
33773 Rev. F https://www.lantronix.com/ Page 13 of 228
To create a schedule:
•From the Web UI:
1. Go to the PoE Schedule page.
2. Press the Add Event button.
3. Select the Profile ID you wish to add events for.
4. Set the Day of the Week, the Hour of the Day, the Minute of the Hour (5 minute intervals on
Web UI), and the Action.
5. The PoE Schedule page for the profile you added the event to should be displayed
a. A Profile can have its name set using the Name textbox at the top.
b. An event can be deleted using the Delete button for the event to be deleted.
•From the CLI, to add a power on at 21:12 on Monday to Profile 1:
configure terminal
poe schedule add 1 monday 21 12 power-on
•From the CLI, to delete the event on Monday at 21:12:
configure terminal
poe schedule delete 1 monday 21 12
•From the CLI, to set Profile 1's name to test:
configure terminal

•From the CLI, to display schedule events:
show poe schedule
To apply a schedule to a port:
•From the Web UI, go to the PoE Configuration page, use the PoE Schedule pulldown for the port you
want to apply the desired Profile, then press the Apply button.
•From the CLI, to apply the schedule Profile 1 to Port 1:
configure terminal
interface GigabitEthernet 1/1
poe schedule 1
To disable the schedule on a port:
•From the Web UI, go to the PoE Configuration page, use the PoE Schedule pulldown for the port you
want to disable the schedule and select Disabled.
•From the CLI:
configure terminal
interface GigabitEthernet 1/1
poe schedule disabled
To see the current status, use the PoE Service Status page in the Web UI or from the CLI:
show poe service
For ports that do not have a schedule, the status will look like this:
Off

Lantronix SESPM1040-541-LT-xx Operation Guide
33773 Rev. F https://www.lantronix.com/ Page 14 of 228
If a port has been disabled by another PoE Service, the status will look like this:
Off - Disabled by service
For ports with a schedule applied, the status will look like this:
Running - Current PoE State: On Next event: Reset, Friday at 01:10
Port Power Monitor Services
The Port Power Monitor will disable a port if its average power draw over the last minute exceeds the
configured amount. The average power is displayed in the Total Power Monitor's status per port on the PoE
Service Status page in the Web UI or with the service status CLI command:
show poe service
Port Power Monitor and Total Power Monitor services use the same values; Total Power Monitor cannot be
disabled so the values are displayed there.
To configure the Port Power Monitor, use the Port Power Maximum field on the PoE Configuration page in the
Web UI or the CLI command sequence:
configure terminal
interface GigabitEthernet 1/<port>
poe maxpower <power in W>
To disable the Port Power Monitor, set the Port Power Maximum to 0 on the PoE Configuration page in the Web
UI or the CLI command sequence (for port 3):
configure terminal
interface GigabitEthernet 1/3
poe maxpower 0
To re-enable a port that has been disabled by the Port Power Monitor, after evaluating the attached PD:
•Use the PoE Configuration page and set the Port Power Maximum to a new value
•Use the PoE Configuration page and set the PoE Mode to Disabled, then back to Enabled.
•Use the CLI commands to set the power limit to something other than the current value:
configure terminal
interface GigabitEthernet 1/<port>
poe maxpower <power in W>
•Use the CLI to disable/enable the port:
configure terminal
interface GigabitEthernet 1/<port>
poe mode disable
poe mode enable
If a PD exceeds the Port Power Maximum threshold:
•Syslog message will be generated:
port(3) power monitor over-power failure, observed port power: 15.5W
•Trap will be generated if traps are enabled:
(get Port Power trap information)
To see the current status, use the PoE Service Status page in the Web UI or from the CLI:
show poe service

Lantronix SESPM1040-541-LT-xx Operation Guide
33773 Rev. F https://www.lantronix.com/ Page 15 of 228
The status message will look like this under normal conditions:
Monitoring -3.1W
If the Port Power Monitor disabled a port, its status will look like this:
Port Disabled - Over power limit detected: 15.5W
If the Port Power Monitor has been disabled by another service (scheduler turning the port off, for example), its
status will look like this:
Off - Disabled by service
If the Port Power Monitor has been disabled by the user, its status will look like this:
Off
To see the current configured Port Power Maximum, look at the setting on the PoE Configuration page in the
Web UI or use the CLI command:
show poe config port 1/<port>
PSU Temperature Monitor Services
The PSU Temperature Monitor is always running and cannot be disabled. To protect the PSU from overheating
and destroying itself, if the PSU Temperature exceeds 76C, PoE on all ports will be disabled until the PSU
temperature drops below 60⁰C.
If the PSU Temperature exceeds the temperature threshold:
•Syslog message will be generated that looks like this:
port(1) PSU over-heating, disabling poe - observed PSU temperature: 77.2C
•Trap is generated if traps are enabled:
(get PSU over temp trap information)
When the temperature returns to a safe level and power is restored:
•Syslog message is generated:
port(1) PSU temperature OK, enabling poe - observed PSU temperature: 59.5C
•Trap is generated if traps are enabled:
(get PSE temp ok trap information)
To see the current status, use the PoE Service Status page in the Web UI or from the CLI:
show poe service
The status message will look like this under normal conditions:
Monitoring - PSU temperature: 41.0C
If the PSU Temperature Monitor shutdown a port, its status will look like this:
Port Disabled - PSU cooling down, PSU temperature: 77.2C
The PSU Temperature Monitor parameter is displayed in the Web UI at PoE Management > PoE Service Status
and in the CLI with the show poe service command.

Total Power Monitor Services
The Total Power Monitor is always running and cannot be disabled. The purpose of this monitor is to keep the
overall power draw on the PSU at or below 180W on the -AC or 240W on the -DC but to allow individual ports to
allocate up to 90W.
A rolling average for the past minute is kept for each port. These averages are summed and when 180/240W is
exceeded, the lowest priority port is shut off. Port shutdown order is as follows:
Configured
Priority
PoE Port
Port 1 Port 2 Port 3 Port 4
Low 4 2 3 1
High 8 6 7 5
Critical 12 10 11 9
If a port is disabled, a syslog message is generated:
port(1) shutdown: PSU Total Power budget of 240W exceeded - observed Total Power draw:
245.2W
If traps are enabled, a trap is generated:
(get total power monitor trap information)
To re-enable a port, set the port to Disabled on the PoE Configuration page and then set it back to Enabled.
To see the current status, use the PoE Service Status page in the Web UI or from the CLI:
show poe service
The status message will look like this under normal conditions:
Monitoring -3.0W
If the Total Power Monitor had to shut down a port, its status will look like this:
Disabled - PSU over power limit
The Total Power Monitor parameter is displayed in the Web UI at PoE Management > PoE Service Status and in
the CLI with the show poe service command.

Software Configuration
Initial Switch Configuration
This manual assumes that the switch was successfully installed as described in the Install Guide. Initial switch
configuration can be via:
•Console Port (Serial) (RS-232 RJ-45) (out-of-band)
•Command Line Interface (CLI) (Telnet or SSH; in-band)
•GUI via Ethernet (in-band)
•NFC (Switch Manager Mobile App)
The factory defaults are IP Address: 192.168.1.10, User Name: admin, and Password: admin.
NFC configuration: all versions are equipped with Near Field Communication (NFC) to allow simple, repeatable
switch configuration with a user-friendly app on a mobile device prior to connecting or powering up the switch.
Using NFC you can configure the switch without it being powered up. When the NFC-enabled device
(smartphone or tablet) and the NFC “tag” or antenna on the switch are in close proximity, a magnetic field is
formed and the power from that magnetic field uses modulation to transfer data. The NFC antenna/tag contains
a nonvolatile EEPROM which retains the data transferred from the smartphone or tablet even after it moves out
of proximity, and the configuration is transferred into the switch’s memory once the switch is fully powered up.
BLE configuration: Bluetooth Low Energy (BLE) allows remote access to alarm information or to read or change
equipment settings without requiring physical access using inconvenient ladders or scissor lift rental.
CLI Configuration
The Command Line Interface (CLI) is a text-based interface that you can access via either a Telnet session or a
direct serial connection to the switch (e.g., a PC running a terminal emulation package such as Tera Term or
HyperTerminal).
Log In to the CLI
At the login prompt SESPM1040-541-LT login: use the factory defaults of IP Address: 192.168.1.10, User
Name: admin, and Password: admin. Note that Login times out after 60 seconds of inactivity. Hit the Enter key,
wait 60 seconds, and then log in again. Example:
