M120 FPC Terminology

This section explains how to avoid damaging the FPCs that you install into routing platforms. Many components on the FPC are fragile.

Caution: Failure to handle FPCs as specified in this document can cause irreparable damage.

This section discusses how to hold FPCs in both the vertical and horizontal positions. Regardless of orientation, this section uses the same terms for all four edges of the FPC (see Figure 1):

• Faceplate—Edge of the FPC that has slots into which you insert the PICs
• Connector edge—Edge opposite the faceplate; this edge has the connectors that attach to the midplane
• Top edge—Edge at the top of the FPC when it is vertical
• Bottom edge—Edge at the bottom of the FPC when it is vertical

Note: The instructions in this section apply to all FPCs.
