Installing The Rear Led/Serial Connector Assembly; Removing And Replacing The Midplane - IBM 8852 - BladeCenter H Rack-mountable Service Manual

Installing the rear LED/serial connector assembly

To install the rear LED/serial connector assembly, complete the following steps.
1. Insert the assembly into the opening in the shuttle bottom; then, carefully slide
it forward until the serial port is seated firmly in the opening on the back panel
of the shuttle.
2. Install the two studs that attach the serial connector to the rear panel of the
shuttle.
3. Install the two screws that connect the circuit board of the assembly to the
bottom of the shuttle.
4. Route the assembly cable and reconnect it to the midplane connector.
Attention: Make sure that the cable is properly routed within the structure of
the shuttle. An incorrectly routed cable can be pinched and damaged when the
shuttle is installed in the BladeCenter unit.
5. Install the shuttle into the BladeCenter unit (see "Installing the shuttle" on page
52).
6. Reconnect the power to the BladeCenter unit (see "Supplying power to the
BladeCenter unit" on page 9).
7. Restart any blade servers that were shut down in the BladeCenter unit. See the
documentation that comes with the blade server for detailed instructions.

Removing and replacing the midplane

Your BladeCenter is equipped with one of two different midplane FRUs,
depending on the media tray connector design. Before you replace a midplane
FRU, identify the part number of the midplane you are replacing either by reading
the FRU label on the midplane or by logging on to the Advanced Management
Module and checking the chassis hardware data. See the Advanced Management
Module User's Guide or the Advanced Management Module Command-Line Interface
Reference Guide for more information about viewing BladeCenter hardware data.
Notes:
1. If your BladeCenter H chassis hardware is version v6 or earlier, install
midplane FRU 25R5780.
