Installing The 10-Gigabit Ethernet X2 Transceiver - Cisco RFGW-10 Hardware Installation Manual

Cabling the Supervisor Engine
Cisco 1000BASE-LX/LH interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard.
However, their higher optical quality allows them to reach 10 km over SMF cable instead of the 5 km
specified in the standard.
If an LR X2 designed for operation on an SMF cable is directly coupled to an MMF cable, an effect
known as Differential Mode Delay (DMD) might occur.

Installing the 10-Gigabit Ethernet X2 Transceiver

Caution
The 10-Gigabit Ethernet X2 transceiver is a static-sensitive device. Always use an ESD wrist-strap or
similar individual grounding device when handling X2 transceivers or coming into contact with
modules.
To install a 10-Gigabit Ethernet X2 transceiver, follow these steps:
Step 1
Using a small flat-blade screwdriver, carefully pry the X2 transceiver port cover off the module
faceplate. Use the two arrows on the port cover as guides for inserting the screwdriver blade. Save the
port cover for future use.
Step 2
Remove the 10-Gigabit Ethernet X2 transceiver from its protective packaging.
Step 3
Check the label on the 10-Gigabit Ethernet X2 transceiver to verify that the 10-Gigabit Ethernet X2
transceiver is the correct model for your network.
Step 4
Grip the sides of the 10-Gigabit Ethernet X2 transceiver sleeve with your thumb and forefinger, and
insert the 10-Gigabit Ethernet X2 transceiver into the X2 socket on the module front panel. You will hear
a click when the X2 transceiver is approximately 90 percent installed. Continue sliding the X2
transceiver into the socket until you hear a second click. The X2 transceiver connector is now mated to
the socket connector. Verify that the X2 transceiver EMI gasket is in contact with the module faceplate.

Tip
With some X2 transceivers you might need to pull out the latching sleeve as you slide the X2 transceiver
into the socket. When the EMI gasket makes contact with the module faceplate, slide the latching sleeve
in to secure the X2 transceiver in the socket.
