HP Controller Enclosure Battery Replacement Instructions (5697-1348, June 2012)

• Port-colored (purple) handles on components like
the battery module means the component is
hot-swappable and can be replaced without
having to power the system down.
• There are two battery modules under the bezel
on the front of the controller enclosure. See
Figure 1 (page 2) for the locations. Each battery
provides power to the controller directly across
from it in the enclosure. Battery 1 (B1) provides
power to controller 2 (C2) and battery 2 (B2)
provides power to controller 1 (C1).
• Your controller enclosure model may vary slightly
from what is illustrated in this document.

Verifying component failure
Use the following methods to verify component failure:
• Analyze any failure messages received. HP Insight
Remote Support Software provides a
recommended fault monitoring solution.
• Verify the battery status using HP P6000
Command View:
1. In the navigation pane, select Storage
system→Hardware→Controller enclosure.
2. In the contents pane, select the Power tab.
The status is displayed in the Cache Battery
fields. An operational state of (Failed)
indicates a fault that can require a battery
replacement.
3. To help identify the correct enclosure in the
rack, select Locate→Locate On in the
Controller Enclosure Properties window. This
causes the blue Unit ID indicator to blink on
the controller enclosure (not the individual
controller in the enclosure).
• Observe the battery module status LEDs.
Solid green—Power turned on and functioning
properly
◦
◦ Blinking green—Maintenance activity in
progress, such as testing or charging
◦ Solid amber—Fault condition that cannot
support cache activity. LUNs have failed over
to the other controller.
◦ Blinking amber—Degraded condition, and
should be replaced soon. Depending on the
charge state of the battery, LUNs may or may
not have failed over to the other controller.
◦ Off—Module not fully connected or powered
down
Removing a battery module
1. Remove the enclosure front bezel by grasping
both ends and pulling it off the enclosure.
Figure 2 Enclosure bezel removal
2. Verify the correct battery module to replace.
Battery 1 powers controller 2 and battery 2
powers controller 1.
NOTE: If the battery amber LED is lit solid,
the LUNs owned by the controller with the
faulted battery have already failed over to
the other controller. If the battery amber
LED is blinking, the LUNs may or may not
have failed over to the other controller, and
if not, will fail over when the degraded
battery is removed.
3. Grasp the handle on the battery module and pull
it out a short distance.
