DC-POWER (Single-Carrier Cabinet Environment)
S8700 MC
only
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.

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:

Port Power Supply provides +5, -5, and/or -48 Volts DC to the circuit packs on the carrier. The
following power supplies are used:
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.
