Removing the capacitor pack
CAUTION: Wear gloves or use care when removing the capacitor pack to avoid physical injury.
CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly
grounded before performing this procedure.
To remove the capacitor pack:
1. Back up all data.
2. Close all applications.
3. Power off the server blade.
4. Remove the server blade from the enclosure by pushing the button to release the handle (1),
pulling the handle toward you (2), and then removing the server blade from the enclosure (3).
5. Press the release button on the access panel and slide the access panel to the left to remove
it.
6. Since the original capacitor pack is connected to a cache module, observe the cache module
LEDs.
• If the amber cache LED is solid, data transfer to the flash device on the cache is in progress.
Do not remove the cache until the amber LED is off, and then continue with the next step.
• If the amber cache LED is not lit, proceed to the next step.
