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.
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).
For a single-carrier cabinet system, refer to the "DC-POWER
(Single-Carrier Cabinet Power)" Maintenance documentation for
environment maintenance strategy.
For a multicarrier cabinet system using an external AC power source, refer
to one or more of the following Maintenance documentation sections:
"AC-POWER (AC Power) for AC-Powered Systems", "CUST-ALM
(Customer-Provided Alarming Device)", or "POWER (Battery & Battery
Charger) for AC-Powered Systems".
For a multicarrier cabinet system using an external DC power source, refer
to one or more of the following Maintenance documentation sections:
"AC-POWER (AC Power) for DC-Powered Systems", "CUST-ALM
(Customer-Provided Alarming Device)", or "POWER (Battery & Battery
Charger) for DC-Powered Systems".
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.
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
together supply the required voltages to the carrier. Figure 10-17 illustrates the
position of the carrier power units and PDU J58890CF and shows which power
unit each circuit breaker controls (Figure 10-17 also shows other Environment
