The Module can be easily damaged by electrostatic 
discharge. To prevent damage, observe the following:

„

Always wear an anti-static wristband connected to a 
suitable earth point.

„

Do not remove the Module from its packaging until 
you are ready to install it into a Switch.

„

Do not touch any of the pins, connections or 
components on the Module.

„

Handle the Module only by its edges and front panel.

„

Always store or transport the Module in anti-static 
packaging.

To install the Module:

1 Your Switch can be either powered-up or 

powered-down.

2 Ensure that you are wearing an anti-static wristband 

connected to a suitable earth point.

3 Undo the two captive thumbscrews securing the blank-

ing plate at the front of the Switch. Do not remove any 
other screws from the front of the Switch.

4 Remove the blanking plate.

5 Keep the blanking plate in a safe place. If you remove 

the Module at any time, you must replace the blanking 
plate to prevent dust and debris entering the Switch and 
to help the circulation of cooling air.

6 Hold the Module so that the text on the front panel is 

upright. Insert it into the Switch, pushing firmly to 
ensure the Module is seated correctly so that the front 
panel is flush with the front of the Switch. Tighten the 
two captive thumbscrews securing the Module with a 
suitable tool.

7 If necessary, power-up your Switch.

There is only one way in which a XENPAK transceiver 
can be installed correctly into the Module. It is not 
necessary to power down your Switch.

1 Insert one of the following XENPAK transceivers into the 

port on the Module:

„

Use this transceiver to connect the Module directly to 
an 8 pair twinaxial copper cable terminated in IEC 
61076-3-113 connectors (between 1m and 15m 
supported).

„

Use this transceiver to connect the Module directly to 
a single-mode fiber-optic cable (up to 40km).

„

Use this transceiver to connect the Module directly to 
a single-mode fiber-optic cable (up to 10km).

2 Hold the XENPAK transceiver so that the text on the 

transceiver is upside down and the module text is shown 
upright. Insert the transceiver, inverted, into the module.

3 Slide the XENPAK transceiver into the XENPAK port on 

the module, pushing firmly to ensure it is seated 
correctly.

4 Tighten the two captive thumbscrews securing the 

XENPAK transceiver with a suitable tool.

5 Remove the plastic protective cover if fitted.

6 Use an appropriate cable to connect the XENPAK 

transceiver to a suitable device.

7 Check the LEDs on the front of the Switch and the front 

of the Module to ensure that the Module is operating 
correctly. Refer to “LEDs” on page 1 for more 
information.

It is not necessary to power-down your Switch.

1 Disconnect the cable from the transceiver.

2 Pull the sleeve around connector towards you to release 

the catch mechanism; the transceiver will then easily 
slide out.

It is not necessary to power-down your Switch.

1 Ensure that you are wearing an anti-static wristband 

connected to a suitable earth point.

2 Undo the two captive thumbscrews securing the Module 

into the Switch using a suitable tool. Do not remove any 
other screws from the Switch.

3 Remove the Module.

4 If you are not fitting another Module immediately, 

replace the blanking plate to ensure that dust and debris 
do not enter the Switch and to help the circulation of 
cooling air.
