Cautions and Warnings
The following conventions are used in this manual to emphasize information important to the reader.
Danger : The described activity or situation might or will cause personal injury.
Warning : The described activity or situation might or will cause equipment damage.
Caution : The described activity or situation might or will cause service interruption.
Note : The information supplements the text or highlights important points.
Safety Instructions
When a connector is removed during installation, testing, or servicing, or when an energized fiber is broken,
a risk of ocular exposure to optical energy that may be potentially hazardous occurs, depending on the laser
output power. The primary hazards of exposure to laser radiation from an optical-fiber system are:
•Damage to the eye by accidental exposure to a beam emitted by a laser source.
•Damage to the eye from viewing a connector attached to a broken fiber or an energized fiber.
Protective earthing is used as a safeguard (required when class I power source was provided).
The equipment power supply cord shall be connected to a socket-outlet with earthing connection, or equivalent
This equipment is only to be connected to PoE networks without routing to outside plants.
DC power source: If the DC power source doesn't ship with the unit: This product is intended to be supplied by a
Listed DC power source whose output is rated 48-57Vdc, 8A minimum and Tma 75 degrees C.
Optional transceiver source: The product is intended to be used with UL approved optional transceiver laser Class
I, rated 3.3V.

DIN-Rail Mounting
1. Screw the DIN-Rail bracket onto the switch with the provided bracket and screws.
2. Hook the unit over the DIN rail.
3. Push the bottom of the unit towards the DIN Rail until it snaps into place.
Wall Mounting
1. Mark and prep holes in the wall surface for mounting.
2. Screw the wall-mount plate onto the switch with the M4 screws provided.
3. Screw the switch and wall mount plate onto the wall (screws not provided).

33841 Rev. A 11
Ground Connection
The switch must be properly grounded for optimum system performance. Use 18 AWG minimum, green and
yellow wires.
Ethernet Interface Connection (RJ45 Ethernet)
The switch provides two types of interfaces: electrical (RJ45) and optical (SFP). To connect the Ethernet interface
via RJ45:
1. Connect to a PC using a straight-through or a crossover Ethernet cable.
2. Connect the switch to an Ethernet device using UTP (Unshielded Twisted Pair) or STP (Shielded Twisted
Pair) Ethernet cables.

Ethernet Interface Connection (Fiber, SFP)
100/1000 Mbps fiber port: Insert an MSA compliant 100 Mbps or 1000 Mbps small form pluggable transceiver
(SFP) in the SFP slot.
For each fiber port there is a transmit (TX) and receive (RX) signal. Make sure that the transmit (TX) port
of the switch connects to the receive (RX) port of the other device, and the receive (RX) port of the switch
connects to the transmit (TX) port of the other device when making your fiber optic connections.
Note: see the related SFP device manual for important Safety warnings. See the Lantronix SFP page for our full
line of SFP transceivers. See the FOA webpage for additional information. The Fiber Optic Association, Inc.is an
international non-profit educational association chartered to promote professionalism in fiber optics through
education, certification and standards.
Do not power up the laser product without connecting the laser to the optical fiber and putting the cover in
position, as laser outputs will emit infrared laser light at this point.

Descriptions of Features Set via DIP Switch
The top panel DIP switch is used to enable/disable Power alarm, broadcast storm limit, Jumbo Frame support,
PoH Mode/802.3bt mode, and PSE Link Pass Through mode as described below.
1. Power Alarm
This setting lets you enable or disable the power alarm. See “Alarm Relay Connection” below.
2. Broadcast Storm Rate Limit
This setting lets you enable or disable the rate limiting of broadcast storms. When enabled, the broadcast storm
limit is 10 Mbps line rate.
3. Jumbo Frame Support
This setting lets you enable or disable the support of jumbo frames of 1519~9216 bytes.

4. PoE PoH / PoE 802.3bt Mode
PoH (Power over HDBaseT): HDBaseT is a global standard for distribution of ultra-high-definition video & audio,
Ethernet, controls, USB and up to 100W of power over a single cable, for up to 100 meters (328 feet).
For PoH information see https://hdbaset.org/.In PoH mode the switch becomes compatible with PDs supporting
PoH mode (pre-bt standard).

5. Enable PoE power cutoff when no SFP link (PSE Link Pass Thru)
DIP switch 5 controls PoE power cutoff when there is no SFP link. This feature is like a media converter's Link fail
Pass Through (LPT) feature.
On: Enable PoE Power Cutoff function when no SFP link.
1. Set the DIP switch to ON.
2. Power ON/OFF the switch; the feature will be applied after reboot.
3. Link up SFP port.
4. Plug in PD device, the switch will deliver power to boot up the PD.
5. Remove SFP link; the Link fail event from the SFP port will pass through to remove power to the PD.
6. Link up SFP port again; PoE power is delivered to PD again.
Off: Disable Power Cutoff function.
1. Switch the DIP switch to ON
2. Cycle power to the switch; the PSE LPT function will be disabled after reboot.

Alarm Relay Connection
The alarm relay output contacts (ALM) are located in the middle of the
DC terminal block connector as shown right and below.
By inserting the wires and setting the DIP switch of the respective Port
Alarm to “ON”, the relay output alarm will detect any port failures and
form a short circuit.
The alarm relay is “Normal Open” and it will be “Closed” when any power
failure is detected. The alarm relay output contacts have a current carrying capacity of 24VDC, 1Amp, via the
2-pin ALM terminal block.

Lantronix SISTP1040-551-LRT Install Guide
33841 Rev. A 16
Power Connection
The switch can be powered from one or two power supplies. Switch power input ranges are:
•48V-57V for PoE
•50V-57V for PoE+
•52V-57V for PoE++
1. Insert the terminal block into the switch top panel receptacle.
2. Insert the positive and negative wires (AWG 14-26) into the PWR + and PWR - contacts on the terminal block
and tighten the wire-clamp screws to prevent the wires from being loosened.
3. Caution: DC power must be connected to an isolated power supply. See chapter 3 Power Supply
Information” on page 17 below.
4. Verify proper LED status; see chapter 4 Troubleshooting LED Status Indicators on page 20 below.
