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.
