power supply 2
Attention: During normal operation, each power-supply bay must have either a
power supply or power-supply blank installed for proper cooling.
To install a power supply, complete the following steps:
1. Slide the power supply into the bay until the retention latch clicks into place.
2. Remove the server cover and install the five cooling fans that come with the
power supply option (see “Installing a hot-swap fan” on page 117); then, install
the cover.
Important: When power supply 1 is installed, the five fans for power supply 1
occupy the rear row only (fans 3, 4, 8, 9, and 10); when both power supplies
are installed, all 10 fans must be installed. See the fan numbers on the
microprocessor air baffle.
3. Connect the power cord for the new power supply to the power-cord connector
on the power supply.
The following illustration shows the power-supply connectors on the back of the
server.

4. Route the power cord through the power-supply handle and through any cable
clamps on the rear of the server, to prevent the power cord from being
accidentally pulled out when you slide the server in and out of the rack.
