Power
The power status LED on the front panel indicates whether the unit has full power (green) or is
in standby mode (amber). A flashing amber light indicates a temperature event that causes the
unit to shut down for approximately 15 seconds. An unlit LED generally indicates that the unit
does not have power.
Critical System
The critical system status LED on the front panel indicates the condition of both the memory
modules (DIMMs) and processors. The memory module (DIMM)
and processor diagnostic
LEDs are located on the system board, as shown in Figure 4-6.
NOTE: The blue status LED indicates that power is supplied to the system board.
