Single-Carrier Cabinet
Environment
Two different cabinet types are supported: multicarrier and single-carrier. Single-carrier cabinets
are used only for PNs. Both cabinet types may be powered by either AC or DC external power
source. Environmental maintenance differs according to cabinet type and external power
supply. Refer to the following table to determine which MO documentation to use for
environmental maintenance.

AC or DC DC-POWER (all environmental maintenance)
Multicarrier AC AC-POWER for AC-powered systems (external power source)

CABINET (temperature and fan sensors)
The DC-POWER MO represents all environmental maintenance for single-carrier cabinets,
whether the external power supply is AC or DC. This includes the external power supply and
every Carrier Port Power Supply in an PN composed of a single-carrier cabinet stack. A Carrier
Port Power Supply provides +5, -5, and/or -48 Volts DC to the circuit packs on the carrier. The
following power supplies are used:
WP-91153 Accepts AC power input
676B Accepts DC power input
Each power unit has one amber LED. A lit LED signifies normal operation. An unlit LED signifies
a loss of external power to the cabinet, or a fault in the power unit. When hardware detects a
problem with any of these components, it reports the information to the system software through
a single lead. System software does not differentiate between different environmental failures.
Since several environmental elements of single-carrier cabinets are logged against the
DC-POWER MO, it is possible to have a DC-POWER alarm while there is still power to the
system.
