Replacing the capacitor pack
1. Connect the replacement capacitor pack to the cache module.
2. Install the cache module in the cache module slot.
3. Install the cache module on the controller, and then close the ejector latches on the cache
module slot.
4. Install the capacitor pack bracket and insert the replacement capacitor pack on the chassis
wall.
5. Install the access panel.
6. Install the server blade in the enclosure.
IMPORTANT: After installing a capacitor pack, you might see a POST message during reboot
indicating that the array accelerator (cache) is disabled temporarily. This behavior is normal
because the new capacitor pack is likely to have a low charge.
The controller operates properly while the capacitor pack is recharging, although the performance
advantage of the array accelerator is absent. You do not need to take any action because the
recharge process begins automatically when you install the capacitor pack. When the capacitor
pack has been charged to a predetermined level, the array accelerator is enabled automatically.
