Backplane Connectors

B.1 Control Shelf Connectors
This section describes the Control shelf backplanes and their connectors. The control shelf
backplane provides connectors for the system circuit cards. These connectors are four
column High Density Interconnect (HDI) male headers with shrouds of varying pin quantities,
depending on card position.
The control shelf backplane provides –48VDC power and ground to all card positions. The
power is distributed into two parts, A and B. Power is brought to the shelf from the Fuse and
Alarm Panel (FAP) using two cables. The connectors on the control shelf backplane are
DB-26 high density connectors. The power is distributed over two separate pins per power
connection to handle the current load.
