1. UU is the universal cabinet number indicated in the PORT field of the alarm log.
The S8700 Sever in a Multi-Connect configuration supports two different cabinet
types: 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.

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

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.
