Many components on the FPC are fragile. Follow these procedures and guidelines to
avoid damaging the FPCs.
CAUTION: Failure to handle FPCs as specified can cause irreparable damage.
When carrying an FPC, you can hold it either vertically or horizontally.
NOTE: An FPC configured with four PICs weighs 12.3 lb (5.6 kg). Be prepared
to accept the full weight of the FPC as you lift it.
You hold an FPC vertically when installing it into the chassis or an equipment rack. If the
FPC is vertical before you grasp it (for example, if it is installed in a router), you can place
either hand around the faceplate and your other hand under the bottom edge.
To hold an FPC vertically (see Figure 51 on page 108):
Orient the FPC so that the faceplate faces you. To verify orientation, confirm that the
1.
text on the FPC is right-side up and that the EMI strips are facing up.
Place one hand around the FPC faceplate about a quarter of the way down from the
2.
top edge. To avoid deforming the electromagnetic interference (EMI) shielding strip,
do not press hard on it.
Place your other hand at the bottom edge of the FPC.
