Before opening the chassis, disconnect the telephone-network cables (from the
card) to avoid contact with the telephone-network voltages.
Do not work on the system or connect or disconnect cables during periods of
lightning activity.
Do not connect a WAN, telephone, or fax cable to the card until you have
completed the installation procedure.
Follow these steps to remove or insert a card in the router:
Make sure that the router is turned off and is disconnected from power.
Power must be disconnected from the system before installing or removing WICs
or VICs to avoid damaging them. When WICs or VICs are pushed into or pulled
out of a router that is powered up, there is a very good chance that they could be
damaged electrically and will no longer function.
Loosen the thumbscrews on the WIC or VIC slot cover, as shown in

You should be able to loosen the screws using your fingers; however, if the screws
