DC-POWER (Single-Carrier Cabinet Environment)<br />

Each power unit has one amber LED. A lit LED signifies normal operation. An unlit LED signifies<br />

a loss of external power to the cabinet, or a fault in the power unit. When hardware detects a<br />

problem with any of these components, it reports the information to the system software through<br />

a single lead. System software does not differentiate between different environmental failures.<br />

Since several environmental elements of single-carrier cabinets are logged against the<br />

DC-POWER MO, it is possible to have a DC-POWER alarm while there is still power to the<br />

system.<br />

If a Carrier Port Power Supply is physically removed from a carrier in a single-carrier cabinet,<br />

there will not be a DC-POWER alarm. DC-POWER maintenance cot distinguish between<br />

removal of the power supply <strong>and</strong> the physical absence of the cabinet.<br />

There is a nominal power holdover of .25 second in an PN single-carrier cabinet.<br />
