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 utilities 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 subsystem comes with sixteen (16) drive trays (see
Figure 1-4
)
designed to accommodate separately-purchased, standard 1-inch pitch, 3.5-
inch SATA disk drives. Two (2) LEDs on the drive tray’s front bezel
indicate drive status. A rotary 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.
The subsystems are housed in an enclosure that is 4 bays wide and 4 bays
high. When viewing from the front, drive bay IDs are numbered from Slot 1
to Slot 16 (see
Figure 1-5
), from left to right, and then from top to bottom.
