SISTP1040-551-LRT
Unmanaged Hardened Gigabit Ethernet PoE++ Switch
Quick Start Guide
This switch is an unmanaged full Gigabit Ethernet hardened PoE++ switch that complies with IEEE
802.3bt, IEEE 802.3at and IEEE 802.3af. The switch has four 10/100/1000Base-T PoE++ ports, one
10/100/1000Base-T port and one 100/1000 dual speed SFP slot. It can deliver up to 90 Watts on
each PoE++ port simultaneously. The SISTP1040-551-LRT can be used to power PoE lighting, high
powered IP cameras and digital signage. It has redundant input power connections to ensure safe,
reliable operation in temperatures of -40°C to +75°C.
Note: If this equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired. Note: See the full Install Guide for important Safety Warnings and Cautions,

Package Checklist
Verify that the box contains one SISTP1040-551-LRT switch, two Wall-mount brackets, one
DIN-Rail Clip, four M4 Screws, one terminal block, this document, and a support postcard.
Note that a Power Supply is not included with the switch (sold separately). An optional
second Power Supply can be ordered separately to provide dual power capability.
DIN-Rail Mounting
1. Screw the DIN-Rail bracket onto the switch with the bracket and screws provided. 2. Hook the unit over the
DIN rail. 3. Push the bottom of the unit towards the DIN Rail until it snaps into place. See the Install Guide.
Wall Mounting
1. Mark and prep holes in the wall surface for mounting. 2. Screw the wall-mount brackets onto the switch with
the M4 screws provided. 3. Screw the switch and wall mount brackets onto the wall (screws not provided).
See the Install Guide.
Front Panel and Top Panel
The front panel provides the LEDs and Ethernet interface connections (RJ45, Fiber/SFP).
The top panel contains the Power and Alarm connections, Ground screw, and DIP switch.
Ground Connection
The switch must be properly grounded for best system performance. This equipment
must be grounded with screw and wire (18 AWG min, 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 crossover
Ethernet cable. 2. Connect the switch to an Ethernet device using UTP or STP Ethernet
cables. See the Install Guide for RJ-45 connector pin assignments and for PoE Deployment
in Environments A and B.

Ethernet Interface Connection (Fiber, SFP)
100/1000 Mbps fiber port: Insert an MSA compliant 100 Mbps or 1000 Mbps SFP in the SFP slot. Note: see the
Install Guide for important TX-RX connection and Safety warnings.
Alarm Relay Connection
The alarm relay output contacts (ALM) are located in the middle of the DC terminal block connector. 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”. See the Install Guide for more
information.
DIP Switch Settings
The 5-position DIP switch labeled SW is located beneath the terminal block connector.
The default is all Off. DIP # 1: Power alarm On/Off. 2: Broadcast storm limit ON/Off.
3: Jumbo Frame support On/Off. 4: On = PoH Mode, Off= 802.3bt Mode.
5: PSE LPT (Link Pass Thru) On/Off. See the Install Guide for more information.
Power Supply Options
Lantronix offers two compatible power supply options: PS-DC-DUAL-5624T and 25160. See the SISPM1040-551-
LRT Install Guide for 25160 information. See the PS-DC-DUAL-5624T Power Supply Install Guide for PS-DC-DUAL-
5624T information.
Power Connection
The switch can be powered by one or two power supplies (input range 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 12-26) into the PWR + and PWR - contacts on the terminal block.
3. Tighten the wire-clamp screws to prevent the wires from being loosened.
See the Install Guide for important information. Note: This equipment is only
to be connected to PoE networks without routing to outside plants.
LED Status Indicators
P1 and P2 (Power Status LEDs): Indication of power input status. ALM (Alarm) LED: On indicates Power failure
alarm. 1G: SFP port speed. 1, 2, 3, 4: Copper port Link/Act status. PoE 1-4: PoE power status of ports 1-5 to PDs.
L/A SFP Link/Act and Speed. See the Install Guide for more detail.
