Battery Status
(continued)
Red Normally, this color indicates that the
battery is bad. However, there are times
when the battery LED turns red for a few
seconds due to other factors and NOT
because the battery is bad. See below.
Hard Disk Busy Green Indicates that at least one of the hard disks
is currently accessing.
Hard Disk
Failure
Green Indicates that all the hard disks installed on
the backplane board are in good condition.
Red Indicates that one of the hard disks installed
on the backplane board is bad.
In these instances, the battery LED may turn red for a few seconds
but DOES NOT necessarily indicate that the battery is bad.
• System Startup
At system power on, the battery LED shows red light when the
system performs initialization and self-tests. The red light should
remain for only a few seconds and eventually turn to green.
• Resumption of AC power supply while the system is running on
battery power.
When AC power is cut-off, the battery automatically supplies the
system power. The sudden return of AC power at this time when
the system is running on battery may cause the battery LED to
change to red. Simultaneously, the message “Battery Fails !”
may appear on the LCD screen. When this happens, allow the
battery to recover for a while. Wait for the battery LED to return
to green and the LCD message to disappear.
If the battery LED remains red for several
seconds and the message “Battery Fails !” still
shows on the LCD screen, change the battery
or call your dealer or a technician for
assistance.
