Dell PowerEdge 2650 - Manual (Page 19)

Power Indicator
The system has indicators on the front panel and the power supplies that denote system power status (see Figure 1 -2 ).
Power Indicator Codes
The power button controls the AC power input to the system's power supplies. The power button indicator can provide information on power status.
Table 1 -4 lists the power-button indicator codes.
SCSI Hard-Drive Indicators
Each SCSI hard-drive carrier has two indicators: a busy indicator and a status indicator (see Figure 1 -3 ). The indicators provide information on the status of
the respective hard drive. Table 1 -5 lists the drive indicator codes.
Figure 1-3. SCSI Hard-Drive Indicators
Table 1 -5 lists the drive indicator codes. Different codes display as drive events occur in the system. For example, in the event of a hard-drive failure, the "drive
fail" code appears. After the drive is selected for removal, the "prepared for removal" code appears. After the replacement drive is installed, the "prepared for
operation, drive online" code appears.
Status LCD
The system's bezel indicator (see Figure 1 -2 ) shows when the system is operating correctly, when the system needs attention, or when the system is being
identified (see " System Identification Indicators "). When the bezel indicator signals an error condition, open the bezel to see further information provided be
the LCD.
The LCD can display two lines of alphanumeric characters. The display codes are presented in two color combinations:
Table 1-4. Power Indicator Codes

system documentation.
