NOTE:
During the power-on process, the ATTEN LED will light up steadily.
Once the subsystem successfully boots up with no faults, the ATTEN LED
is turned off.
4.4.3 Drive Tray LEDs
Two (2) LED indicators are located on the right side of each drive tray. (See
Figure 4-4 ) Refer to Table 4-3 for the LED definitions. When notified by a
drive failure message, you should check the drive tray indicators to find the
correct location of the failed drive. Replacing the wrong drive can fatally
fail a logical array.
