– For 14 DIMMs: A1, A2, A4, A5,
A7, A8, A9, A10, B1, B2, B3, B4,
B5, B6
Mirroring population order A{1, 2, 3, 4, 5, 6}, B{1, 2, 3, 4, 5,
6}
Mirroring is supported with 6 DIMM
slots per processor.
Single rank sparing population order A{1}, B{1}, A{2}, B{2}, A{3},
B{3}...
Populate in this order, odd amount per
processor allowed. Requires two ranks
or more per channel.
Multi rank sparing population order A{1}, B{1}, A{2}, B{2}, A{3},
B{3}...
Populate in this order, odd amount per
processor allowed. Requires three
ranks or more per channel.
Removing a memory module
Prerequisites
1 Follow the safety guidelines listed in Safety instructions.
2 Power o the system and all attached peripherals.
3 Disconnect the system from the electrical outlet, and disconnect the peripherals.
4 Open the drive bays, remove all drives, and then close the drive bays.
5 Remove the power supply units.
6 Remove the system from the rack and place it on an ESD work bench. For more information, see the Rail Installation Guide available at
www.dell.com/poweredgemanuals.
7 Remove the system cover.
8 Remove the air shroud.
Locate the appropriate memory module socket.
WARNING
: Allow the memory modules to cool after you power o the system. Handle the memory modules by the card edges
and avoid touching the components or metallic contacts on the memory module.
Steps
1 Push the ejectors outward on both ends of the memory module socket to release the memory module from the socket.
2 Lift and remove the memory module from the system.
CAUTION
: Handle memory modules only by the card edges, ensuring not to touch the middle of the memory module or
metallic contacts.
NOTE: If you are removing the memory module permanently, install a memory module blank. The procedure to install a
memory module blank is similar to that of the memory module.
