Adding 6-Port MICA Modules to a Digital Modem Network Module
Cisco Network Modules Hardware Installation Guide 10-8
Removing the Digital Modem Network Module
Follow this procedure to remove a digital modem network module:
Step 1
Turn OFF electrical power to the router. However, to channel ESD voltages to
ground, do not unplug the power cable. Remove all network interface cables,
including telephone cables, from the rear panel.
The following warning applies to routers that use a DC power supply:
Step 2
Loosen the module’s captive mounting screws, using a Phillips or flat-blade
screwdriver.
Step 3
Hold the captive screws between two fingers, and pull the network module
toward you until it slides free of the chassis. (See Figure 10-4.)
Step 4
Set the network module on an ESD-preventive mat.
Caution
Network modules do not support online insertion and removal (hot swap). To
avoid damaging the module, before you remove a network module from a chassis slot, you
must turn OFF electrical power and disconnect network cables.
Warning
Before performing any of the following procedures, ensure that power is
removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker
on the panel board that services the DC circuit, switch the circuit breaker to the OFF
position, and tape the switch handle of the circuit breaker in the OFF position.
