Installing memory modules

Adding memory to your server is an easy way to make programs run faster. You
can increase the amount of memory in your server by installing memory-module
options. When you install memory, you must install a pair of matched double data
rate (DDR) dual inline memory modules (DIMMs).
Attention:
synchronous dynamic random-access memory (SDRAM) with error correcting code
(ECC) DIMMs. These DIMMs must be compatible with the latest PC2100 (CL2.5)
specification, and downward compatible with PC1600 (CL2) SDRAM Registered
DIMM specification, which is available from http://www.jedec.org/ on the World Wide
Web. For a list of supported options for your server, go to
http://www.ibm.com/us/compat/ on the World Wide Web.
Notes:
1. The system board contains four DIMM connectors and supports two-way
2. The DIMM options available for your server are 256 MB, 512 MB, and 1 GB.

finger into the depression at the left side of the filler panel and pulling it away
from the server.
a. Ensure that the tray handle is open (that is, perpendicular to the drive).
b. Align the drive assembly with the guide rails in the bay.
c. Gently push the drive assembly into the bay until the drive stops.
d. Push the tray handle to the closed (locked) position.
e. Check the hard disk drive status LED to verify that the hard disk drive is
operating properly.
If the amber hard disk drive status LED for a drive is lit continuously, that
individual drive is faulty and needs to be replaced. If the green hard disk
drive activity LED is flashing, the drive is being accessed.
Note: If you have a RAID configuration on your server using the integrated
SCSI controller with RAID capabilities, or if your server has a RAID
adapter installed, you might need to reconfigure your disk arrays after
installing hard disk drives. See the RAID documentation on the IBM
xSeries Documentation CD for information about RAID adapters.
Install only 2.5 V, 184-pin, double-data-rate (DDR), registered
memory interleaving.
Your server supports a minimum of 512 MB and a maximum of 4 GB of
system memory.
