Chapter 5. Installing options 51
Note: You do not have to turn off the server to install hot-swap hard disk drives
in these bays.
3. Remove the filler panel from one of the empty hot-swap bays by inserting your
finger into the depression at the left side of the filler panel and pulling it away
from the server.
4. Install the hard disk drive in the hot-swap bay:
a. Ensure that the tray handle is open (that is, perpendicular to the drive).
b. Align the drive tray assembly with the guide rails in the bay.
c. Gently push the drive tray assembly into the bay until the drive stops.
d. Push the tray handle to the closed (locked) position.
e. Check the hard disk drive status light to verify that the hard disk drive is
operating properly.
If the amber hard disk drive status light for a drive is lit continuously, that
individual drive is faulty and needs to be replaced. If the green hard disk
drive activity light is flashing, the drive is being accessed.
Note: If your server has a ServeRAID controller, you might need to reconfigure
your disk arrays after installing hard disk drives. Refer to the information
that comes with your ServeRAID controller.
5. If you have other options to install or remove, do so now.
Installing memory modules
Adding memory to your server is an easy way to make programs run faster. You can
increase the amount of memory in your server by installing options called memory-
module kits. Each kit contains one industry-standard, dual in-line memory module
(DIMM). Your server uses a noninterleaved memory configuration.
Your server comes with a DIMM that is installed on the system board in DIMM
connector 1 (labeled DIMM 1).
Notes:
1. When installing additional memory modules, install the second memory module
in the connector labeled DIMM 2, the third in connector DIMM 3, and the fourth
in connector DIMM 4. (See the following illustration for memory-connector
locations.)
2. Your xSeries 220 server supports 128 MB, 256 MB, 512 MB, and 1 GB DIMMs.
These DIMMs can be installed in any memory slot. Your server supports a
minimum of 128 MB and a maximum of 4GB of system memory. See the
ServerProven list at http://www.ibm.com/pc/compat/ for a list of memory
modules for use with your server.
3. Installing or removing DIMMs changes the configuration information in the
server. Therefore, after installing or removing a DIMM, you must save the new
configuration information by using the Configuration/Setup Utility program.
When you restart the server, the system displays a message indicating that the
memory configuration has changed. Start the Configuration/Setup Utility
program and select Save Settings. See “Chapter 3. Configuring your server,” on
page 11 for more information.
