Power-on LED
When on, this green light indicates that the unit has adequate dc power.
General-system-error LED
When on, this amber LED indicates that the storage server has a fault, such
as in a power supply, fan unit, or hard disk drive.
Note:
If the General-system-error LED is on continuously (not flashing),
there is a problem with the storage server. Use the storage
management software to diagnose and repair the problem. For more
information, see “Checking the LEDs” on page 40.
Hot-swap drive CRU
You can install up to 10 hot-swap drive CRUs in the storage server. Each
drive CRU consists of a hard disk drive and tray.
Filler panel
The storage server comes without drives installed and contains filler panels
in the unused drive bays. Before you install new drives, you must remove
the filler panels and save them. Each of the 10 bays must always contain
either a filler panel or a drive CRU. Each filler panel contains a filler piece
for use with a slim drive.
Drive activity LED
Each drive CRU has a green Drive activity LED. When flashing, this green
LED indicates drive activity. When on continuously, this green LED
indicates that the drive is properly installed.
Drive fault LED
Each drive CRU has an amber Drive fault LED. When on, this amber LED
indicates a drive failure. When flashing, this amber LED indicates that a
drive identify or rebuild process is in progress.
Latch This multipurpose blue latch releases or locks the drive CRU in place.
Tray handle
You can use this multipurpose handle to insert and remove a drive CRU in
the bay.
For information on how to install and replace drive CRUs, see the appropriate IBM
TotalStorage DS4000 Product Installation Guide. For more information about the
LEDs, see “Checking the LEDs” on page 40.
