LED remains red. If the other common
equipment is already installed and opera-
tional, the status LED is red at first, but turns
green within 20 seconds.
9.3.2 Software Settings
There are no software settings necessary to set up
a FOCUS Power Supply Module.
9.4 Specifications
The FOCUS Power Supply Module’s technical
specifications are shown in Table 9-1.
9.4.1 Status Indicators
This module has three status indicators, as shown
in Figure 9-2. The red/green status LED is green if
the module is functional and the rest of the
chassis/ common equipment is also functional.
The red major alarm LED, controlled by the
Maintenance Module, is lit for any of the
following conditions:
• Complete power supply failure
• Loss of synchronization
• System alarms (e.g., nonvolatile RAM
failure/lithium battery failure, digital cross-
point switch IC failure, T1 IC framer
failure, or maintenance module failure)
•Failure of certain voltage regulator supplies
