2.3.4 Control Module
2.3.4.1 Overview
In a standard configuration, the control module consists of two ECMs, one dry contact card,
and one monitoring interface card (from left to right). The four cards are hot swappable. One
subrack is reserved above the dry contact card. A backfeed protection card or dry contact
extended card can be inserted into this subrack.
