Removing the support bracket assembly
When working with some options such as hard disk drives and microprocessors,
you must first remove the support bracket assembly to access the location of the
option. The support bracket assembly consists of a support bracket, an air baffle,
and a fan.
Do the following to remove the support bracket assembly:
1. Review the information in “System reliability considerations” on page 56.
2.
Turn off the server and peripheral devices and disconnect all external cables
and power cords.
3. Remove the side cover (see “Removing the side cover” on page 57).
4. If the server is a non-hot-swap model, continue with step 7 on page 60.
5. If the server is a hot-swap model, press down on the latches on either side of
connector J42, and remove the voltage regulator module (VRM) from connector
J42. (See “System board options connectors” on page 53 for connector location.)
Note:
Remember to reinstall this VRM after you reinstall the support bracket
assembly.
6. Disconnect the fan cable (connector J10) from the system board. (See “System
board internal cable connectors” on page 53 for connector locations.)
Note: Remember to reconnect this cable after you reinstall the support bracket
assembly.
