Removing a RAID adapter remote battery holder
Use this information to remove a RAID adapter remote battery holder.
When you install any RAID adapter that comes with batteries, it is sometimes necessary to install the
batteries in another location in the server to prevent the batteries from overheating.
To install a RAID adapter remote battery in the server, complete the following steps:
1. Read the safety information that begins in "Safety" on page v and "Installation guidelines" on page 169.
2. Turn off the server (see "Turning off the server" on page 24) and all attached peripheral devices.
Disconnect all power cords; then, disconnect all external cables from the server.
3. Carefully turn the server on its side so that it is lying flat, with the cover facing up.
Attention: Do not allow the server to fall over.
4. Unlock and remove the left-side cover (see "Removing the left-side cover" on page 193).
5. See the documentation that comes with the adapter for any cabling instructions and information about
jumper or switch settings. It might be easier for you to route cables before you install the adapter.
6. Remove the remotely installed RAID adapter battery (see "Installing a RAID adapter remote battery or
flash power module in the server" on page 68 ).
