Working with Memory Modules

Working with Memory	Modules
Adding		system memory to		your	server is an easy way		to make programs
You	can increase		the	amount	of	system memory by installing options calle
memory modules. The server uses a						noninterleaved memory	configuration, with
error		correcting	code	(ECC)	data	protection.

Notes:

1.Your server comes with one or more dual-inline memory modules (DIMM)s installed.

2. The server supports 100 MHz, 64 MB, 128 MB, and 256 MB DIMMs.

3. Install only registered SDRAM ECC DIMMs.

4.When you are installing memory modules, you might find it more effi install them in adjacent connectors, with no vacant memory connectors i between. For example, if your server only has one DIMM installed in connector J15, install additional memory in the J16 memory connector;

continue with connectors J17 and J22.

5. If you are installing DIMMs of	different sizes, you	might	find it
install DIMMs with the greater	memory capacity starting	with	connector
For example, when installing two 256 MB DIMMs, install the		DIMMs	in memor
connectors J15 and J16.

6.After installing or removing a DIMM, you must save the new configurati information using the Configuration/Setup Utility program. See “Using the Configuration/Setup Utility” on page 22.

Installing or Removing		Memory		Modules
	This section gives the procedure for installing							memory	modules. If you
	remove		a	memory	module, reverse	the following	steps.
		Before	you	begin
	Ÿ
		Read		“Electrical Safety” on		page 41 and	“Handling		Static-Sensitive De
		on	page 42.
	Ÿ	Read		the	documentation that	comes with	the	option.

1.If you have not done so, remove the server cover. See “Preparing Options” on page 43.

2.Locate the memory-module connectors on the system board (see “Syste Board Connectors” on page 169).

Notes:
a. Each	connector slot	contains	two keys	(dividers),	which are used
that	a memory-module	can be	installed	only in the	correct position

b. A retaining clip at each end of the connector locks the memory place.

3.Press the retaining clips at the ends of the connector downward to position.
