3.1 Overview
The cards for the ONS 15454 SDH include front mount electrical connection cards (FMECs), common
control cards, electrical cards, optical cards, and Ethernet cards. Each card is marked with a symbol that
corresponds to a slot (or slots) on the ONS 15454 SDH shelf assembly. The cards are then installed into
slots displaying the same symbols (refer to the Cisco ONS 15454 SDH Installation and Operations
Guide, R3.3 for a list of slots/symbols). The overview in this section provides a summary of the cards.
