WF-500-B Appliance Hardware Reference
Description
of the equipment rack. Push the UID button again
to deactivate these LEDs.
Solid green indicates that the appliance is powered
on.
Solid red indicates that either a power supply failed
or that there is no power source connected to a
power supply.
Blinking yellow indicates IDE channel activity (SAS/
SATA drive) on the front log drives.
• Solid red—An overheat condition occurred.
• Blinking red at the rate of one blink per second
(1Hz)—A fan failure occurred.
• Blinking red at the rate of one blink every four
seconds (.25Hz)—One of the two power supplies
is not providing power to the appliance (possibly
because a power supply failed or because there
is no power source connected to the power
supply).
• Solid blue—The UID feature is activated (see the
UID button description for the
Panel.)
Disk drive bays and HDDs used for log storage.
By default, the WF-500-B ships with four HDDs
installed in drive bays A1/A2 and B1/B2. You can
install up to eight additional drives (four additional
RAID 1 pairs) in the remaining drive bays (C1/C2,
D1/D2, E1/E2, and F1-F2) to increase log storage
capacity.
Each pair of drives are in a RAID 1 configuration.
For example, A1-A2 is a RAID 1 pair and B1-B2 is a
RAID 1 pair.
Status LEDs—two for each log drive:
• Top LED—Flashing blue indicates drive activity.
• Bottom LED—Solid red indicates a log drive
failure.
