assignments.

Online Spare Memory Configuration

In the online spare configuration, the ROM automatically configures the last
populated bank as the spare memory. If only banks A and B are populated,
bank B is the spare bank. If banks A, B, and C are populated, bank C is the spare
bank. If DIMMs in a non-spare bank exceed the limit for the single-bit
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:
•
•
After installing DIMMs, use RBSU to configure the system for online spare
memory support.

DIMM Installation Guidelines

You must observe the following guidelines when installing additional memory:
•
•
•
•
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.
Always install memory in pairs of two identical DIMMs.
Install only PC2100 Registered DDR SDRAM DIMMs, 2.5 volts, 72 bits
wide, and ECC.
Install DIMMs with the same speed.
Install DIMMs into both slots within a single bank. Install DIMMs in order.
