Generic 1 offers two basic cabinet type configurations: (1) the multicarrier
cabinet system and (2) the single-carrier cabinet system. Both cabinet system
configurations may be powered by either an external AC or DC power source.

NOTE:
For environment maintenance, the PPN or EPN cabinet configuration
aspects for a High or Critical Reliability system are irrelevant.
For environment maintenance, the PPN or EPN cabinet configuration
aspects for a High or Critical Reliability system are irrelevant.
The environment maintenance strategy to be used depends on both the cabinet
configuration and the type of powering. Therefore, refer to the following list to find
the appropriate MO section(s).

Every carrier in the system must be supplied with +5 volt, -48 volt, and -5 volt DC
power for the various circuit packs to operate properly. A multicarrier system can
be supplied by an external AC power source or an external DC power source.
power for the various circuit packs to operate properly. A multicarrier system can
be supplied by an external AC power source or an external DC power source.
In a DC-powered system, power is supplied to the carriers as follows: DC power
from an external device comes into Power Distribution Units (PDU J58890CF and
PDU J58890CF-1), which distribute the power via circuit breakers (CB1-CB12 for
PDU J58890CF, CB1-CB6 for J58890Cf-1) to the carrier power units. Each carrier
in the system is equipped with two power units, the 644A and the 645B, which
