Installing memory modules (DIMMs)
You can install additional memory modules to the Model 200, which includes one
256-MB DIMM.
This section describes how to replace a memory module. It consists of four steps:
1. Prepare to install the memory module (see “Preparing to install a memory
module”).
2. Remove the cover (see “Removing the cover” on page 15).
3. Install the memory module (see “Adding the memory module” on page 17).
4. Replace the cover (see “Replacing the cover” on page 19).
Preparing to install a memory module
Read these notes before installing a memory module.
Note:
v
Become familiar with the safety and handling guidelines specified under
“Handling electrostatic discharge-sensitive devices” on page 76.
v
The blue color on components and labels inside your Models 200 and 225
identifies touch points where a component can be gripped, a latch moved,
and so on. The only exception to this is the power supplies, which are
orange.
v
Make sure that you have an adequate number of properly grounded
electrical outlets for Models 200 and 225 and any other options that you
intend to install.
v
Have a small, flat-blade screwdriver available.
v
Before you begin installing components, read the safety information found
in “Translated safety notices” on page 77.
v
For translations of the safety notices that are included in this guide, refer
to
Safety Information .
System reliability considerations: To help ensure proper cooling and system
reliability, make sure that:
v
Each of the drive bays has either a drive or a filler panel installed.
v
The cover is in place during normal operations, or is removed for no longer than
30 minutes while the appliance is operating.
Note: The front door (Model 200) can be removed permanently without affecting
system reliability.
v
There is space around the appliance to allow the appliance cooling system to
work properly.
– For Model 200, leave about 127 mm (5 in.) of space around the front and rear
of the appliance.
– For Model 225, refer to the documentation that comes with the rack.
v
A removed hot-swap drive is replaced within 2 minutes of removal.
v
Cables for optional adapters are routed according to the instructions provided
with the adapters.
v
A failed fan is replaced within 48 hours.
