HP ProLiant DL740 Server - Manual (Page 114)

Installing Hardware Options, Hot-Plug
Hot-Adding Memory
For the hot-add feature to work on the ProLiant DL740 server, the operating system
must have driver support. Refer to “Installing HP Drivers and Utilities” in Chapter 8
for details on installing HP software. HP recommends having all DIMMs that will be
added available before beginning this procedure.
CAUTION: A redundant memory configuration is required when performing Hot Plug
RAID Memory functions.
• If all five memory cartridges are online and error free, any memory cartridge can
be removed.
• If one of the five memory cartridges requires attention, only that memory
cartridge can be removed.
• If two or more memory cartridges require attention and are online (cartridge
power LED is illuminated), then no cartridge can be removed. An audible alarm
will sound if any cartridge is unlocked.
IMPORTANT: You cannot perform a hot-add of memory if only four memory cartridges are
installed. The system must have a redundant memory configuration (five memory cartridges
online and error-free) before you can remove any memory cartridge.
