The following describes the indicators on the PDX 218 front panel (see Figure 1-2).
Figure 1-2. PDX218 Indicators
Power indicator; green LED lighted when the power switch on the rear panel is
On.
Disk Activity indicators; two banks of four green LEDs show disk activity. Each
bank corresponds to a SCSI bus with four disk drives. Mapped to the physical
location of each hard disk drive in the chassis, the LEDs flash when activity
occurs on the associated disk. A LED that never flashes on or remains on may
indicate a problem with the associated disk.
System Fault indicator; red LED off during normal operation. Lights to indicate
either a terminal power failure or (with 4 below lighted) a fan failure.
Fan Fault indicator (behind the front panel bezel and only visible with the bezel
removed); red LED off during normal operation. Lights (along with 3 above) to
indicate a fan failure.
