1. Product Description
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 31.) 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 10/100/1000Base-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.

on -AC version or 240 Watts total on -DC version).
PSE or PD Configuration
Can be used to provide PoE to other devices or to receive and provide PoE
where external power sources are not available.
6kV Surge Protection
Protects switch from lightning or other surges in current.
NEMA 4X/IP66 Rated
Enclosure
Protects switch from harsh outdoor environments, including rain, dust, and
insects and can be easily mounted on a pole, wall or building.

Feature
Benefit
RADIUS
Provides RADIUS Client enable/disable and configuration of 1-4 Radius Servers
for authentication purposes.
TACACS+
Provides TACACS+ Client enable/disable and configuration of 1-4 TACACS+
Servers for authentication purposes.
SSH v2 Server
Secure Shell (SSH) cryptographic network protocol allows setup of Host and
User Public-Key Settings via RSA public-key encryption technology or DSA
using FIPS (Federal Information Processing Standard) for digital signatures.
Configuration Backup and
Restore
Backup and Restore running-config, startup-config, or default-config via TFTP
or SCP (future). For example, save the startup-config file to ensure that the
currently active configuration will be used at the next reboot.
Tamper Detection
The switch includes a 3-axis linear accelerometer that detects if the switch has
exceeded user-selected vibration limits, indicating someone is tampering with
the switch or the switch mount has somehow been compromised.
Cable Diagnostics /
Virtual Cable Test (VCT)
The Cable Diagnostics uses TDR (Time Domain Reflectometry) for remote
identification of potential cable malfunctions. The Cable Diagnostics detect
and report potential cabling issues such as pair swaps, pair polarity, and
excessive skew. It can also detect cable opens, shorts, or impedance mismatch
in the cable and report accurately within one meter the distance to the fault.
MAC Address Table
Switching of frames is based on the DMAC address contained in the frame.
The switch builds a table that maps MAC addresses to switch ports for
knowing which ports the frames should go to (based on the DMAC address in
the frame). Provides both static and dynamic entries. The static entries are
configured by the network administrator to do a fixed mapping between the
DMAC address and switch ports.
Port VLAN
Create a VLAN and associate a VLAN ID with it. Assign a Switch Port to a VLAN
(create an association between a port on the SESPM switch and a previously
created VLAN). Define the Switch Port usage type (trunk or access) and set
Allowed VLANs.
DMI (Diagnostic Monitoring
Information)
View DMI (Diagnostic Monitoring Information) including SFP Temperature,
Voltage, Bias, TX and RX power, and Vendor info (part number, serial number,
revision, date code).
DHCP Server
This module lets you view and configure up to 5 DHCP server instances.
A DHCP Server can automatically provide and assign IP addresses, default
gateways and other network parameters to client devices. You can add,
modify and delete DHCP Server pool entries on a table to configure Start IP,
End IP, Lease Time, Subnet Mask, Default Router, and DNS Server. The page
also lets you add a new interface where the VLAN field is configurable.
