NOTE:  The wire gauge for the terminal block  should be in the range between 12 ~ 24 
AWG. 
For the GE-DSH-82-PoE, A 48VDC, 3A power in put is required for full PoE load on the 
PoE. Please connect an external power sour ce to the terminal block that can supply 
steady power at 48VDC.  
Wiring the Fault Alarm Contact 
The fault alarm contacts are in the middl e of the terminal block connector as the 
picture shows below. Inserting the wires, th e Industrial Switch will detect the fault 
status of the power failure, or port link fa ilure (available for managed model) and then

Wiring the Digital Inputs / Outputs (GE-DSH-73) 
There is another terminal block comprising  two sets of digital input/output contacts 
on the topside of GE-DSH-73. Please refer  to the Digital Input/Output section for how 
to configure Digital Input/Output. The followi ng illustration shows the pin assignment 
of the DIDO connector. Please  note do not connect DO0/DO1 to the external device 
using power higher than 40V/200mA.

Installing the SFP transceiver 
The section describes how to insert an  SFP transceiver into an SFP slot. 
The SFP transceivers are hot pluggable  and hot swappable. You can plug-in and out 
the transceiver to/from any SFP port withou t having to power down the Industrial 
Switch. Shown in Figure 2-19.

Approved GE Security SFP Transceivers 
GE Security Industrial Switch supports both Single mode and Multi-mode SFP 
transceiver. The following list of approved  GE Security SFP transceivers is correct at 
the time of publication: 
o SFP1000SX-220 SFP (1000Base-SX SFP transceiver / Multi-mode / 850nm / 
220m~550m)  
o  SFP1000LX-10Km SFP (1000Base-LX SFP transceiver / Single mode / 1310nm / 
10km) 
o  SFP100FX1310-TSC-2Km SFP (100Base-FX SFP transceiver / Multi-mode / 
1310nm / 2km) 
o  SFP100FX1310-TSC-20Km SFP (100Base-FX SFP transceiver / Single mode / 
1310nm / 20km) 
NOTE:  We recommend using GE Security SFPs  on the Managed Industrial Switch. If 
you insert a SFP transceiver that is not su pported, the Managed Industrial Switch will 
not recognize it. 
Before connecting the other switches, workstation or Media Converter: 
1. Make sure both side of the SFP tran sceiver are with the same media type, for 
example: 1000Base-SX to 1000Base-SX, 1000Bas-LX to 1000Base-LX. 
2. Check the fiber-optic cable type match the SFP transceiver model. 
o To connect to 1000Base-SX SFP transceiver,  use the Multi-mode fiber cable- 
with one side must be male  duplex LC connector type. 
o  To connect to 1000Base-LX SFP transceive r, use the Single-mode fiber cable-
with one side must be male  duplex LC connector type. 
 
•  Connect the fiber cable 
1. Attach the duplex LC connector on the  network cable into the SFP transceiver. 
2. Connect the other end of the cable to a de vice - switches with SFP installed, fiber 
NIC on a workstation or  a Media Converter. 
3. Check the LNK/ACT LED of the SFP slot  on the front of the Managed Industrial 
Switch. Ensure that the SFP transceiver is operating correctly. 
4. Check the Link mode of the SFP port if th e link failed. Co works with some fiber-NICs 
or Media Converters, set the Link mode to 1000 Force is needed.

•  Remove the transceiver module 
1. Make sure there is no network activity  by consulting or checking with the network 
administrator or through the management  interface of the switch/converter (if 
available) to disable the port in advance. 
2. Remove the Fiber Optic Cable gently.

3. Turn the handle of the MGB module horizontally. 
4. Pull out the module gently through the handle.

NOTE:  Never pull out the module without pull th e handle or the push bolts on the 
module. Pulling out the module with too much force could damage the module and 
SFP module slot of the Managed Industrial Switch.

X-Ring Application 
The industrial Switch supports the Rapid Ri ng (X-Ring) protocol that can help the 
network system to recovery from network co nnection failure within 20ms or less, and 
make the network system more reliable. The  X-Ring algorithm is similar to spanning 
tree protocol (STP) algorithm but its recovery  time is faster than STP. The following 
figure is a sample X-Ring application.

Coupling Ring Application 
In the network, it may have more than one X-Ring group. By using the coupling ring 
function, it can connect each X-Ring fo r the redundant backup. It can ensure the 
transmissions between two ring groups not to  fail. The following figure is a sample of 
coupling ring application. 
 
Dual Homing Application 
Dual Homing function is to prevent the  connection lose from between X-Ring group 
and upper level/core switch. Assign two port s to be the Dual Homing port that is 
backup port in the X-Ring group. The Dual  Homing function only works when the X-
Ring function is active. Each X-Ring  group only has one Dual Homing port. 
 
NOTE: In Dual Homing application architectu re, the upper level switches need to 
enable the Rapid Spanning Tree protocol.
