Installing a Cisco
Step 1 Attach an antistatic wrist strap to your wrist and to a bare metal, unpainted surface on the chassis or frame.
Step 2 Face the back of the Cisco uBR10012 chassis. Clear enough interface and power cables to allow sufficient space to work.
Step 3 If installing a new cable interface line card in a blank slot, remove the blank slot cover and discard it. Otherwise, disconnect all coaxial cables from the cable interface line card being replaced or removed.
Step 4 Unscrew the top and bottom captive screws on the cable interface line card (Figure 5).
