Follow these steps to install the card in a Cisco 1721 router:
Make sure that the power switch is set to the STANDBY position (
the power cable is not connected to the power socket on the rear panel.
Power must be removed from the system prior to installing or removing WICs
to avoid damaging them. When WICs 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 slot cover on the rear panel, as shown in
Figure 2-2, and then remove the slot cover. You should be able to loosen the
screws using your fingers; however, if the screws are very tight, you might need
to use a Phillips screwdriver.
