or XFP transceivers
■ Connector edge—Edge opposite the faceplate; this edge has the connectors that
attach to the midplane
■ Top edge—Edge at the top of the DPC when it is vertical
■ Bottom edge—Edge at the bottom of the DPC when it is vertical
NOTE: The instructions in this section apply to all DPC types.
