Installing a Network Module
• When you insert several pluggable transceiver modules in multiple switch ports, wait for 5 seconds
between inserting each module. This will prevent the ports from going into error disabled mode. Similarly,
when you remove a pluggable transceiver module from a port, wait for 5 seconds before reinserting it.
Procedure
Step 1
Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.
Step 2 Find the send (TX) and receive (RX) markings that identify the top of the transceiver module.
On some modules, the send and receive (TX and RX) markings might be shown by arrows that show the
direction of the connection.
Step 3 If the pluggable transceiver module has a bale-clasp latch, move it to the open, unlocked position.
Step 4
Align the module in front of the slot opening, and push until you feel the connector snap into place.

Step 5 If the module has a bale-clasp latch, close it to lock the module in place.
Step 6
Remove the dust plugs and save.
Step 7 Connect the transceiver cables.
