Chapter 2 Installing Cisco Network Modules in Cisco Access Routers
Installing Cisco Interface Cards in 1- or 2-Slot Network Modules
Warning
To avoid electric shock, do not insert a WAN or voice interface card into a 2-slot module while power
is on or network cables are connected.
Statement 68
Caution
Do not perform OIR on interface cards in 1- or 2-slot network modules. To avoid damage to the interface
card and to the network module, turn off electrical power and disconnect network cables before inserting
an interface card into a network module slot.
Step 2
Remove all network cables, including telephone cables, from the rear panel of the router.
Timesaver
To make it easier to work with network cables, label the cables or prepare a network cabling diagram
before removing network interface cables from the network module.
Step 3
Using a number 1 Phillips or flat-blade screwdriver, loosen the screws on the blank interface card
faceplate. (See
Figure 2-16
.) Remove the blank faceplate.
Figure 2-16 Blank Interface Card Faceplate
Tip
Save blank interface card faceplates for future use.
Step 4
Align the interface card with the guides in the slot on the network module and slide it gently into place
until the edge connector is seated into the connector on the module. (See
Figure 2-17
.)
