After MISPs are installed, install SILCs, UILCs and BRSCs, as required. As
the cards are installed, keep a list of the card type (BRSC, SILC or UILC), the
module number, and the number of the card slot containing the card. Use the
CE/PE Module card location form or the IPE Module card location form at
the end of this chapter to document this information.

backplane connector.
