Removing and Installing an Alarm Card
Figure 8 Alarm Card Locations in the Upper and Lower Card Cages
Removing an Alarm Card from the Upper Card Cage
Note The router alarm card supports online insertion and removal (OIR). This allows you to remove and install
an alarm card while the router remains powered up.
To remove the alarm card from the upper card cage, use Figure 9 as a reference and follow these steps:
Step 1 Grasp the outside edges of the upper card cage front cover and pull it straight out to detach the front
cover from the ball stud sockets on the front of the card cage.
Step 2 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection
sockets on the front of the chassis or to a bare metal surface on the chassis (see Figure 3 on page 10).
