FPC Description  FPC Description   The FPCs on a router house the Physical Interface Cards (PICs), which connect the router to  network media. The I/O Manager ASIC or ASICs on the FPC accepts incoming data packets  from the PICs on the FPC and divides each packet into 64-byte cells. The cells cross the  midplane to the SFM, where another ASIC decides how to distribute them among the  memory buffers located on and shared by all installed FPCs. After the SFM decides how to  forward a

FPC Description  M20 FPC Description   In an M20 router, up to four FPCs install horizontally into the midplane from the front of the  chassis, below the System and Switch Board (SSB). Each FPC is referenced by the number of  the slot in which it is installed. The slot numbers range from FPC0 through FPC3, from top to  bottom in the chassis. Each FPC accommodates up to four PICs. Figure 1 shows a chassis  with FPCs—each housing four PICs—installed in all four slots.   Figure 1: M20

FPC Description  M40 FPC Description   In an M40 router, up to eight FPCs install vertically into the backplane from the front of the  chassis, four on either side of the System Control Board (SCB). Each FPC is referenced by the  number of the slot in which it is installed. The slot numbers range from FPC0 through FPC7,  from left to right in the chassis. Each FPC can accommodate up to four PICs. Figure 2 shows  an FPC housing four PICs installed in slot FPC7.   Figure 2: M40 Route

Replace an FPC in an M20 Router  Replace an FPC in an M20 Router   On an M20 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:   !

Place one hand underneath the FPC to support it, and slide it completely out of the  chassis. Set the FPC on the antistatic foam mat prepared in Step 1, component-side  down and with the PIC faceplates facing you.    To avoid damaging any components, use extra care when  laying the FPC on the antistatic mat, particularly if the mat  is not made of foa

Slide the FPC straight into the card cage until it contacts the midplane.    When about 1 in. (2.5 cm) of the FPC remains outside the  slot, adjust the insertion speed so that it takes between 1  and 15 seconds for the FPC to contact the midplane.  Completing the insertion too quickly or too slowly can  cause the router

Replace an FPC in an M40 Router 4. Take the FPC offline by pressing and holding its offline button for 5 seconds or until the  green OK LED next to the button goes out. The offline button for each FPC is located on  the craft interface just below 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 sy

Replace an FPC in an M40e or M160 Router  Do not leave a transceiver uncovered. The safety cap keeps  the port clean and prevents accidental exposure to laser  light.   Avoid bending fiber-optic cable beyond its minimum bend  radius. An arc smaller than a few inches in diameter can  damage the cable and cause problems that are difficult to  diagnose.    6.
