HP ProLiant DL740 Server - Manual (Page 115)

Installing Hardware Options, Hot-Plug
To install additional DIMMs in the server, you must add them 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.
1. Begin with memory cartridge 1 and:
a. Unlock the cartridge and lift it out of the server by following the procedure in
the “Removing the Memory Cartridge” section of this chapter.
CAUTION: Do not remove a memory cartridge if the cartridge power LED is
blinking or is solid green. The system will halt.
If the cartridge power LED has not turned off after unlocking the
cartridge, then one of the following conditions exists:
• Another cartridge is either powered down or removed.
• Another cartridge in the system has errors.
b. Add the additional memory 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 HP 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-add
operation.
CAUTION: When handling a DIMM, be careful not to touch any of the contacts.
Doing so may damage the DIMM.
NOTE: Be sure DIMMs are installed in the proper orientation. The DIMMs are keyed to
ensure they are installed correctly in the memory socket.
c. Be sure that all of the DIMM socket levers are rotated inward.
d. Insert the memory cartridge in the server with the cartridge lock in the
unlocked position, and then secure it in place by rotating the cartridge lever
down.
