Installing the Second Power Supply (8270-800 Only)
If you have the optional redundant (second) power supply it should be installed at
this time. If the 8270-800 is to be rack-mounted, you should not attempt to install
the power supply before the 8270-800 chassis is mounted in the rack since the
weight of the supply can make the rack-mounting procedure difficult.
Step
1. Remove the power supply and all accompanying documentation from the
shipping container.
Step
2. Read all of the documentation provided with the power supply before
installing the power supply in the 8270-800.
Note: The second power supply can be hot-plugged. If you are
installing this power supply in an existing installation, do not disconnect
power from the 8270-800 or remove the existing power supply.
Step
3. Remove the blank cover from the power supply slot in which the power
supply is to be installed from the front of the 8270-800 by removing the
two thumbscrews holding it in place. Retain the plate and the
thumbscrews for use in the event that the power supply is ever removed.
Step
4. Insert the power supply module into the open slot until the supply is firmly
seated in the connectors at the back of the slot. See Figure 2-11.
