Hardware Maintenance Manual: xSeries 200
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, open and close the clips gently.
c. Insert the DIMM into the connector by aligning the DIMM edges with the
slots at each end of the DIMM connector. Firmly press the DIMM straight
down into the connector by applying pressure on both ends of the DIMM
simultaneously. Be sure that the retaining clips snap into the locked position
when the DIMM is firmly seated in the connector.
d. If a gap exists between the DIMM and the retaining clips, the DIMM has not
been properly installed. In this case, open the retaining clips and remove the
DIMM; then, reinsert the DIMM.
e. If you removed the AGP adapter, reinstall it now, see “Installing an adapter”
on page 45.
6. If you have other options to install or remove, do so now.
7. Replace the support bracket assembly and reconnect the fan cable to the
connector (SYSFA3) on the system board. See “Removing the support bracket
assembly” on page 42 and “System board internal cable connectors” on page 36
for the location of the fan cable connector.
8. Replace the side cover, see “Installing the cover” on page 59.
9. Reconnect the external cables and power cords, and turn on the peripheral
devices and the server.
If you want to remove a DIMM, reverse the previous steps.
Removing and installing a microprocessor
The server only supports one microprocessor, which is installed on the system board
in the microprocessor connector (U5).
Notes:
1. Before you install a new microprocessor, review the documentation that comes
with the microprocessor, so that you can determine whether you need to update
the server BIOS. The latest level of the BIOS for your server is available through
the World Wide Web.
2. For a list of supported operating systems, see
http://www.ibm.com/pc/us/compat/ on the World Wide Web.
Note: The illustrations in this document might differ slightly from your hardware
Attention: To avoid damage and ensure correct server operation when you install a
new microprocessor, use a microprocessor that has the same cache size and type, and
the same clock speed. Microprocessor internal clock frequencies and external clock
frequencies must be identical. See the ServerProven list at
http://www.ibm.com/pc/compat for a list of microprocessors for use with your
server.
