Replace a P

Up to four regular PICs install into an M5 router and up to eight regular PICs install into an M10

router, as

shown in Figure 1 and Figure 2. Quad-wide PICs occupy all four slots in an FPC row.

Both regular and quad-wide PICs are hot-removable and hot-insertable. A removed PIC

no longer

receives or transmits data, and removing or inserting a PIC briefly interrupts

forwarding of traffic through the remaining PICs.

To replac

e a PIC, perform the following procedures:

• Remove a PIC on page 87

• Install a PIC on page 89

Remove a PIC

To remove a PIC, follow this procedure (see Figure 30):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the

PIC. If the PIC connects to fiber-optic cable, have ready a rubber safety cap for each

transceiver and cable.

2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect

the strap to one of the ESD points on the chassis. Fo r more information about ESD, see

“Prevent Electrostatic Discharge Damage” on page 134.

3. If the PIC has multiple cable connector ports, label the cable connected to each port, to

make it easier to reconnect the cables correctly.
