Grounding
After the Injector is mounted and connected, the back panel grounding
screw can be used for grounding. Grounding and wire routing help limit the
effects of noise due to electromagnetic interference (EMI).
Note: Run the ground connection from the ground screw to the grounding
surface before connecting devices.
Caution: Avoid Improper Grounding
Required:
Isolated DC Supply
Connect chassis to earth ground
Do not connect earth ground to:
Negative input terminal
Positive input terminal
DIP Switch
The front panel DIP Switch is used to configure the SFP operating speed. The default position is
Mode 2, 1000M.
DIP Switch Definition
Status Description
Mode 1 100M
Mode 2 1000M
The SFPs are hot-swappable. However, you must cycle device power
whenever the DIP switch is changed (i.e., whenever changing SFP mode/speed).

Ports
RJ45 ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for 10Base-T, 100Base-TX or
1000Base-T device connections. Auto MDI/MDIX means that you can connect to another switch or
workstation without changing straight through or crossover cabling. See information below for
straight through and crossover cable PIN assignments.

Note: The “+” and “-” signs represent the polarity of the wires that make up each wire
pair.
All ports on this Hardened PoE injector support automatic MDI/MDI-X operation, so you can use
straight-through cables (see below) for all network connections to PCs, servers, or to other switches
or hubs. In straight-through cables, pins 1, 2, 3, and 6, at one end of the cable, are connected
straight through to pins 1, 2, 3 and 6 at the other end of the cable. The table below shows the
10BASE-T/ 100BASE-TX /1000Base-T MDI and MDI-X port pin outs.

Cabling
A twisted-pair segment can use unshielded twisted pair (UTP) or shielded twisted pair (STP)
cabling. The cable between the powered device and the injector must be less than 100 meters
(328 ft.) long and comply with the IEEE 802.3ab 1000Base-T standard for Category 5e or above.
The Fiber segment using a single-mode connector type must use 9/125μm single-mode fiber
cable. You can connect two devices at a distance of 10 km. Fiber segment using multi-mode
connector type must use 50/125 or 62.5/125μm multi-mode fiber cable. You can connect two
devices at a distance of 550m.
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical
communications for both telecommunication and data communication applications.
See the Lantronix SFP web page for more small form factor pluggable (SFP) transceivers
information.
Refer to the SFP manual for important safety information.

Wiring the Power Inputs
Follow the steps below to insert the power wire.
1. Locate the labeling on the device indicating the location of V+ and V- power input connections
on the device.
2. Insert the positive and negative wires into the V+ and V- contacts on the terminal block
connector.
3. Tighten the wire-clamp screws on the terminal block, highlighted in red above, to secure the
wire connections.
Note: The wire gauge for the terminal block should be 12~ 24 AWG.
Note: Adjust the power supply as required. These devices accept 48~57VDC; higher voltage
(50~57VDC) may be required for some high powered PD loads.

4 Troubleshooting
□Select the proper UTP cable to construct your network. Use unshielded twisted-pair (UTP) or
shielded twisted-pair (STP) cable for RJ45 connections: 100Ω Category 3, 4 or 5 cable for
10Mbps connections, 100Ω Category 5 cable for 100Mbps, or 100Ω Category 5e/above
cable for 1000Mbps connections. Also be sure that the length of any twisted-pair connection
does not exceed 100 meters (328 feet).
□Diagnosing LED Indicators:To help identify problems, monitor the SI-IES-1x1D-LRT front
panel LED indicators that provide the device’s current status. These LEDs can help diagnose
common problems you may encounter during installation.
□Verify that you are using the right power cord and power adapter.
□If the SI-IES-1x1D-LRT is not producing full PoE+ output, ensure the power supply is
adjusted to provide the required input power. The converters accept 48~57VDC; higher
voltage (53~57VDC) required for some high powered PD loads. See Wiring the Power Inputs
on page 13.
□If the power LED does not light when the power cord is plugged in, you may have a problem
with the power cord or power source. Check for loose power connections, power losses and
power at the power outlet. If you still cannot resolve the problem, contact Lantronix technical
support for assistance.
□If the Injector/Converter LEDs are normal, the connected cables are correct, and the device
fails to transmit data, check your system’s Ethernet devices’ configuration or status.
□Check the DIP switch setting. The devices ship defaulted to 1000Base-T on the DIP switch.
When changing the speed from 1000Base-T to 100Base-T, the unit must be power cycled
after installing the 100Base-T SFP and setting the DIP switch to 100 Mbps. Then it will link at
100Base-T. See DIP Switch on page 8.
