LED Readout Displays “HP” (the default) or the unit identification number
during normal operation, displays status information during
a self-test or warns of an error condition.
Chassis Keylock The front bezel is locked to the chassis with the key lock
near the top of the bezel. When the bezel is in place, it
effectively locks the chassis door.
SCSI Device
Shelves Standard SCSI devices, such as a DAT tape drive or an
independent hard disk drive, can be installed in the SCSI
device shelves.
Drive Activity
(LED) Light The LED lights while the drive spins up. It goes off when
the drive has spun up and is idle and flashes when the drive
in the module is reading or writing data. If, after the drive
has spun up, the light remains on, the drive may be hung. If
you suspect the drive is hung, refer to the “Troubleshooting”
chapter in this manual.
Drive Power
(LED) Light Indicates the status of drive power and warns of an over
temperature condition. The LED lights green when the disk
module has been fully inserted into the shelf and power is
good.
If a single drive is flashing yellow, it indicates a faulty
power condition. If all the drives in a cage are flashing
yellow, it indicates a possible over temperature condition. If
all the drives in a cage are flashing red, it indicates the
temperature has exceeded the operational range.
Immediately begin shut-down procedures and refer to the
“Troubleshooting” chapter in this manual.
Hot-Swap Disk
Module Keylock When locked, the key is required to remove a hot-swap disk.
Only one key is needed to remove or install any disk
module. The key also matches the chassis keylock.
