Installing Hardware Options, Hot-Pluggable To upgrade memory, replace existing DIMMs with new ones in bank pairs across all five of the memory cartridges, one cartridge at a time. You must add memory and bring the cartridge back online before taking the next cartridge offline. IMPORTANT: Hot-upgrading memory results in the system switching into a safe memory timing mode from the time the first cartridge is installed with upgraded memory until all five cartridges have upgraded memory and the memory is made available to the operating system. During this time some applications may show a decrease in performance, but the system continues to operate. 1. Begin with memory cartridge 1: a. Unlock the cartridge and slide it out of the server following the procedure in "Removing the Memory Cartridge" section of this chapter. b. Lift the memory cartridge cover and remove the DIMMs you are upgrading. c. Install the new memory in the same sockets from which the DIMMs have been removed in accordance with the following guidelines: - Similar DIMMs must be installed in bank pairs and in bank pair order (1+2, then 3+4, then 5+6, then 7+8). - DIMMs must be of the same speed, type, and size. They should have the same part number (for example 123456-12x, where x is not required to match). - More than one bank pair can be installed during a single hot-upgrade operation. CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module. NOTE: Be sure memory modules are installed in proper orientation. The modules are keyed to ensure that they are installed correctly in the memory socket. d. Be sure that all of the DIMM socket levers are rotated inward before closing the cartridge cover and then close the memory cartridge cover. e. Insert the memory cartridge in the server and secure it in place by closing the cartridge ejector lever. HP ProLiant DL760 Generation 2 Server User Guide 5-21
