7. If you removed the PCI riser-card assembly to install the adapter, press the PCI
riser-card assembly firmly into the connector so that the retention latch is
engaged.
Note: Make sure that the PCI riser-card assembly is properly seated on the
system-board connector and that the cables under the PCI riser-card
assembly are not pinched.
8. Connect any needed cables to the adapter.
Attention: When you route the cables, do not block the ventilated space
around any of the fans. In addition, route any cables that are plugged into the
PCI adapter under adjacent adapters so they are not pinched between the top
edge of the adapter and the server side wall.
9. If you have other options to install or remove, do so now; otherwise, go to
“Completing the installation” on page 17.
Installing memory modules
When you install memory, you must install a pair of matched double-data-rate
(DDR) dual-inline-memory modules (DIMMs). Before you install memory, review the
following:
v
The system board contains four DIMM connectors and supports two-way memory
interleaving.
v
The DIMM options available for your server are 256 MB, 512 MB, and 1 GB.
v
The amount of usable memory will be reduced, depending on the system
configuration. The BIOS will display the total amount of installed memory and the
amount of configured memory.
v
Your server supports a minimum of two 256 MB DIMMs (for a total of 512 MB)
installed in the DIMM 1 and DIMM 2 memory connectors (J1 and J2,
respectively). When you install additional DIMMs, install them in pairs, with the
next pair in DIMM connectors 3 and 4 (J3 and J4).
v
Both DIMMs in a pair must be the same size, speed, type, and technology. You
can mix compatible DIMMs from various manufacturers.
