Holding an MX960 FPC

Caution: Many components on the FPC are fragile. Failure to handle FPCs as specified in this document can cause irreparable damage.

Note: An FPC configured with PICs installed can weigh as much as 18 lb (8.2 kg). Be prepared to accept the full weight of the FPC as you lift it.

Caution: To prevent damage when handling or carrying FPCs:

As you carry the FPC, do not bump it against anything. FPC components are fragile.
Do not grasp the FPC anywhere except places that this document indicates. In particular, never grasp the connector edge, especially at the power connector in the corner where the connector and bottom edges meet (see Figure 1).
Figure 1: Do Not Grasp the Connector Edge
Do not carry the FPC by the faceplate with only one hand (see Figure 2).
Figure 2: Do Not Carry an FPC with Only One Hand
Do not rest any edge of an FPC directly against a hard surface (see Figure 3). If you must rest the FPC temporarily on an edge while changing its orientation between vertical and horizontal, use your hand as a cushion between the edge and the surface.

You hold an FPC vertically when installing it into the chassis or an equipment rack. To hold an FPC vertically (see Figure 4):

Orient the FPC so that the faceplate faces you.
Place one hand around the FPC faceplate about a quarter of the way down from the 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. If the FPC has heat sinks about midway between the faceplate and connector edge, place your other hand against the heat sinks.
