IBM TotalStorage DS4300 Turbo, Installation And User Manual

Page: 39 / 164

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.
Exception: Because a DS4300 single-controller storage server (Model
6LU/6LX) has only one power supply, this LED cannot light up when its
power supply fails.
Note: If the General-system-error LED is on continuously (not flashing),
there is a problem with the storage server. Use the Storage Manager
client to diagnose and repair the problem. For more information, see
“Checking the LEDs” on page 51.
Locator LED
When on, this blue light indicates the storage-management software is
locating the server.
Hot-swap drive CRU
You can install up to 14 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 installing new drives, you must remove the
filler panels and save them. Each of the 14 bays must always contain either
a filler panel or a drive CRU to ensure proper cooling, air ventilation, and
EMI compliance.
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 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 “Working with
hot-swap drives” on page 74. For more information about the LEDs, see “Checking
the LEDs” on page 51.
