correctable errors threshold as defined by the Pre-Failure Warranty, the system copies the memory
contents of the failing bank to the spare bank. The system then deactivates the failing bank and
automatically switches over to the spare bank.
For online spare memory support, you must observe the following guidelines:
• Dual-rank DIMMs can not be installed in any DIMM socket with online spare memory enabled.
• The ROM must be up to date.
• DIMMs installed in a spare bank must be of equal or greater capacity than the DIMMs installed in
other banks.
For example, if bank A is populated with two 256-MB DIMMs and bank B is populated with two
512-MB DIMMs, bank C must be populated with two 512-MB or greater DIMMs in order for online
spare memory support to function properly.
After installing DIMMs, use RBSU to configure the system for online spare memory support (" Configuring
online spare memory " on page 81 ).
Installing DIMMs
1. Power down the server (on page 27 ).
2. Extend the server from the rack, if applicable (" Extend the server from the rack " on page 28 ).
3. Remove the access panel (" Removing the access panel " on page 29 ).
4. Open the DIMM slot latches.
5. Install the DIMM.
6. Install the access panel (" Installing the access panel " on page 29 ).
7. If you are installing DIMMs in an online spare configuration, use RBSU to configure this feature
("
Configuring online spare memory " on page 81 ).
Hot-plug SCSI hard drive options
When adding SCSI hard drives to the server, observe the following general guidelines:
• A maximum of 14 SCSI devices per channel can be added.
• Each SCSI drive must have a unique ID. The system automatically sets all SCSI IDs.
