Installing Memory-Module Kits
The kits must be installed in pairs of the same size, type, and speed.
You can install up to 256 MB of EOS in your server. The
memory-module kit sizes available for your server are 16 MB and
32 MB. The available speed for these kits is 70 ns.
Notes:
Ÿ Parity memory-module kits are supported in the PC
Server 520 but must not be used in combination with EOS
memory-module kits.
Ÿ
The PC Server 520 does not support memory expansion
adapters.
Before you begin, be sure you have:
Ÿ Read “Electrical Safety” on page 179 and “Handling
Static-Sensitive Devices” on page 180.
Ÿ Removed the server side cover (see “Preparing to Install
Options” on page 181).
When you are instructed to install the kits (in step 3 on page 189),
install them in pairs of adjacent memory connectors, with no vacant
memory connectors in between. Each pair of connectors is a bank.
The memory riser card has four banks: 0, 1, 2, and 3. Your server
comes with at least two memory-module kits installed in bank 0,
the bank located nearest to the memory riser card connector. Install
additional memory-module kits in bank 1, and then continue with
banks 2 and 3, in that order. If you need to install kits of a different
size in bank 0, remove the preinstalled kits as described in
“Removing Memory-Module Kits” on page 192, and install two
other kits as described in this section.
