Installing a redundant power supply and fans
You can install a second 920-watt hot-swap power supply. This upgrade option
includes a hot-swap power supply and three hot-swap fans. You must also
purchase a second power cord to connect the power supply to a power source.
To install the redundant power and cooling option, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 28.
2. Remove the left-side cover (see “Removing the left-side cover” on page 48 for
more information).
Attention: To ensure proper system cooling, do not leave the cover off the
server for more than 2 minutes.
3. Carefully lay the server on its side so that it is lying flat and facing up.
Note: Do not allow the server to fall over.
4. Remove the three fan air baffles from the fan bays of the fan cage assembly
with your finger. Slide the orange release tab in the direction indicated by the
arrow on top of the fan to unlock the fan handle. Grasp the fan handle and pull
the fan out of the fan cage assembly.
Hot-swap fan
5. If you are instructed to return the hot-swap fan, follow all packaging
instructions, and use any packaging materials for shipping that are supplied to
you.
6. Touch the static-protective package that contains the hot-swap fan to any
unpainted metal surface on the server; then, remove the fan from the package
and place it on a static-protective surface.
7. Align the fan over the fan slot and lower the fan into the slot in the fan cage.
8. Press down on the fan until it locks into place; then close the handle to the
locked position.
