Installing the virtual media key
To install a virtual media key, complete the following steps:
1. Align the alignment bracket on the rear of the key with the retention tab on the
system board; then, slide the key down into the virtual media key connector on
the system board until it is firmly seated in place.

2. Reinstall any adapters that you removed.
3. Close the rear adapter-retention bracket.
4. Install and lock the left-side cover (see “Installing the left-side cover” on page
181).
5. Lock the left-side cover.
6. Reconnect the external cables and power cords; then, turn on the attached
devices and turn on the server.
Installing memory
The following notes describe the types of dual inline memory modules (DIMMs) that
your server supports and other information that you must consider when you install
DIMMs.
Attention: Do not mix UDIMMs and RDIMMs in the same server.
v
The server supports industry-standard double-data-rate 3 (DDR3), 800, 1066, or
1333 MHz, PC3-10600R-999 (single- or dual-rank), registered, synchronous
dynamic random-access memory (SDRAM) dual inline memory modules (DIMMs)
with error correcting code (ECC). See http://www.ibm.com/servers/eserver/
serverproven/compat/us/ for a list of supported memory modules for the server.
v
At least one DIMM must be installed for each installed microprocessor for the
server to operate, but three DIMMs per microprocessor improves server
performance.
v When two microprocessors are installed in the server, distribute the DIMMs
between the two microprocessors to improve server performance.
v
The server supports a maximum of 16 single- or dual-rank DIMMs.
