16 FPC Installation Instructions
On an M40e or M160 router, the FPCs are hot-insertable and hot-removable, so you can
remove and replace them without powering down the router. When you remove an FPC, the
router continues to function, but the PICs installed on the FPC do not receive or transmit
data.
For instructions, see the following sections:
! Remove an FPC from an M40e or M160 Router on page 16
! Install an FPC in an M40e or M160 Router on page 18
The FPCs on an M40e or M160 router are located on the front of the chassis below the craft
interface. Each FPC weighs up to 15 lb (6.8 kg).
To remove an FPC, follow this procedure:
1. Place an antistatic mat on a flat, stable surface to receive the FPC. If removing an
M40e-FPC from an M40e router, use a foam mat; if one is not available, substitute a
standard flat antistatic mat but use extra care when laying the M40e-FPC on it to avoid
damaging the electrical components. If any of the PICs on the FPC use fiber-optic cable,
also have ready a rubber safety cap for each transceiver and cable.
2. Attach an ESD strap to your bare wrist and connect the strap to one of the ESD points on
the chassis.
3. Label the cables connected to each PIC on the FPC so that you can later reconnect the
cables to the correct PICs.
4. Take the FPC offline by pressing and holding down its offline button for about 5 seconds
or until the red FAIL LED next to the button lights. The offline button for each FPC is
located on the craft interface directly above the FPC slot.
5. Disconnect the cables from the PICs on the FPC. If a PIC uses fiber-optic cable,
immediately cover each transceiver and the end of each cable with a rubber safety cap.
Arrange the disconnected cables in the cable management system directly below the
FPC card cage, to prevent the cables from developing stress points.
Do not look directly into the ends of fiber-optic cables or
into the transceivers on the PIC faceplate. Single-mode
fiber-optic cable and the PICs that use it (such as ATM and
SONET/SDH interfaces) emit laser light that can damage
your eyes.
