Step 1 Remove the SMB card from the packaging. Line up the connectors on the card with the mating
connectors on the backplane. Gently push the card until both sets of connectors fit together snugly.
Step 2 Place the EIA panel over the card.
Step 3 Insert and tighten the nine perimeter screws (P/N 48-0358) at 8 to 10 lb. (3.6 to 4.5 kg) to secure the
cover panel to the backplane.
Step 4 Insert and tighten the twelve inner screws (P/N 48-0004) at 8 to 10 lb. (3.6 to 4.5 kg) to secure the cover
panel to the card and backplane.
If you are using SMB EIAs to make DS-1 connections, you need the DS-1 electrical interface adapter,
commonly referred to as a balun (P/N 15454-WW-14=).
Figure 1-7 on page 1-20 shows an SMB EIA installation.
