design facilitates the ease of installation and maintenance procedures. Hot-
swap mechanisms are incorporated to eliminate power surges and signal
glitches that might occur while removing or installing these modules. Each
component is further described below:
1.3.1 LCD Keypad Panel
PN: GAL-9273CHandLLCD
The LCD keypad panel consists of a 2-rows x 16-characters LCD screen
with push buttons and LED status-indicators. The LCD keypad panel
provides full access to RAID configuration utility and monitoring functions.
After powering up the subsystem, the initial screen will display the
subsystem’s model name. A different name can be assigned to the
subsystem for ease of identification in a topology consisting numerous
arrays.
1.3.2 Drive
Tray
Figure 1-4: Drive Tray Front View
PN: GAL-9273CDTray
The RAID subsystem comes with sixteen (16) drive trays (see
Figure 1-4
)
designed to accommodate separately purchased standard 1-inch pitch, 3.5-
inch SAS/SATA disk drives. Two (2) LEDs on the drive tray’s front bezel
indicate drive status. A rotary bezel lock on each drive tray prevents
unintentional ejection, and a convenient release button releases the drive
tray from chassis.
WARNING!
Be careful not to warp, twist, or contort the drive tray in any way (e.g., by
dropping it or resting heavy objects on it). The drive tray has been
customized to fit into the drive bays in the subsystem. If the drive bay
superstructure is deformed or altered, the drive trays may not properly fit
into the drive bay.
