Chapter 3 Removing and Replacing FRUs 69

1. Remove the PCI Express card.

See “ToRemove the Optional PCI Express Card” on page 58.

2. Remove the fan tray assembly and cable.

See “ToRemove the Fan Tray Assembly” on page 60.

3. Remove the power supply and cable.

“ToRemove the Power Supply” on page 61

4. Remove the hard drive and cable.

See “ToRemove the Hard Drive” on page 63.

5. Remove the memory DIMMs.

See“ToRemove DIMMs” on page 65.

6. Remove the socketed system configuration SEEPROM from the motherboard and

place it on an antistatic mat.

The system configuration SEPROM contains the persistent storage for the host ID

and Ethernet MAC addresses of the system, as well as the ALOM configuration

including the IP addressesand ALOM user accounts, if configured. This information

will be lost unless the system configuration SEEPROM is removed and installed in

the replacement motherboard.The PROM does not hold the fault data, and this data

will no longer be accessible when the motherboard a nd chassis assembly is

replaced.

The location of this SEEPROM is shown in Appendix A,“Field-Replaceable Units

(FRUs)” on page 75.
