Table 4-5 OK LED Status for AC-input and DC-input Power Supply Units
LED State Power Supply Unit Condition
On (green) The output voltage is in the required range (between 11.9 and 12.1 VDC).
Off The output voltage is not within the required range. (is greater than 12.1
VDC or less than 11.9 VDC)
Table 4-6 Power LED (on front panel) Status for AC-input and DC-input Power Supply
Units
LED State Power Supply Unit Condiiton
Continuous green Corresponding power supply unit is present and functioning normally
Red Corresponding power supply unit present, but malfunctioning
Unlit Corresponding power supply unit is either not present or has failed.
Note
Simple Network Management Protocol (SNMP) monitors the activity of the power supplies. In most
cases when a power supply problem occurs, an SNMP trap is sent in SNMP and the appropriate
message is posted on the SCE 2000 CLI.
