Installing Hardware Options • All DIMMs installed must be the same speed. Do not install DIMM modules supporting different speeds. NOTE: The server ships with DIMMs installed in DIMM slots 1A and 2A. • Install DIMMs into both slots within a single bank. DIMMs must be installed in order. Upgrade memory by installing DIMM pairs into banks in sequential bank order, starting with bank B. CAUTION: Use only HP or Compaq branded DIMMs. DIMMs from other sources are known to adversely affect data integrity. Online Spare DIMM Installation Guidelines For online spare memory support, you must observe the "Standard ECC DIMM Installation Guidelines" in this chapter and the following additional guidelines: • The system ROM must be up-to-date. NOTE: If you are installing optional DIMMs before powering up the server for the first time, it is not necessary to update the system ROM. • Online spare memory support must be enabled through RBSU. • The health driver must be installed and operating properly. • 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 for online spare memory support to function properly.
