the right side of the baffle covers the lip on the side of the power-supply cage.

4. Press the DIMM air baffle into place.

5. Install the cover (see “Installing the cover” on page 91).

Attention: For proper cooling and airflow, replace the air baffle before turning on

the server. Operating the server with an air baffle removed might damage server

components.

Removing the riser-card assembly

The server comes with one riser-card assembly that contains two PCI Express x8

connectors. You can replace the riser-card assembly with one that contains two

PCI-X 64-bit 133 MHz connectors that support single-width IXA adapters. See the

list at http://www.ibm.com/servers/eserver/serverproven/compat/us/

for a list of riser-card assemblies that you can use with the server.
