Electrical Cards
This chapter describes Cisco ONS 15454 electrical card features and functions. For installation and card
turn-up procedures, refer to the Cisco ONS 15454 Procedure Guide. For information on the electrical
interface assemblies (EIAs), see the "Electrical Interface Assemblies" section on page 15.
Chapter topics include:

3.1 Electrical Card Overview

For software and cross-connect card compatibility information, see the "Card Compatibility" section on
page 2.
Each card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 shelf assembly.
The cards are then installed into slots displaying the same symbols. See the "Cards and Slots" section
on page 42 for a list of slots and symbols.
Table 3-1 lists the Cisco ONS 15454 electrical cards.
