Network-related card requirements
Circuit card removal and replacement procedures can be stand-alone
procedures or they can become part of a larger procedure. As a stand-alone
procedure, you insert a spare circuit into a unit to make sure that the card
functions correctly. You can also use card replacement steps as a part of a
larger procedure, for example, alarm clearing.
Refer to Card Replacement Procedures for descriptions of card replacement
procedures for the double shelf network equipment (DSNE) and the
enhanced network (ENET).
