3. Check the hard disk drive status indicators to verify that the hard disk drives are
operating correctly. The Hard Disk Drive Status LED is immediately to the right
of the hard disk drive.

When the green LED flashes rapidly (three flashes per second), the controller
is identifying the hard disk drive.
v
When the green LED flashes slowly (one flash per second), the hard disk
drive is being rebuilt.
v
When the amber LED is on continuously, the hard disk drive has failed.
Installing memory modules
Your appliance comes with two or more dual inline memory modules (DIMM)
installed on the system board in the DIMM connectors. You can install an additional
1 GB of memory in both models.
Notes:
1. Memory modules must be installed or replaced in matched pairs.
2. The Models 110 and 210 are shipped with two DIMMs installed in DIMM slots 1
and 4. These slots must be filled for correct operation. You can install additional
DIMMs as a matched pair in DIMM slots 2 and 3.
To install a memory module:
1. Prepare to install the memory module (see “Preparing to install a memory
module”).
2. Remove the cover (see “Removing the cover” on page 13).
3. Install the memory module (see “Installing and replacing a memory module” on
page 14).
4. Replace the cover (see “Replacing the cover” on page 17).
Preparing to install a memory module
Before installing a memory module:
v
Become familiar with the safety and handling guidelines specified under
“Handling electrostatic discharge-sensitive devices” on page 54.
v
The blue color on components and labels inside your Models 110 and 210
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 correctly grounded electrical
outlets for the engines and any other options that you intend to install.
v
Before you begin installing components, read the safety information found in
“Appendix C. Safety notices” on page 47.
Memory modules must be added, installed, or replaced two modules at a time.
System reliability considerations: To help ensure correct cooling and system
reliability, make sure that:
v
Each of the drive bays has either a hard disk drive or a filler panel installed.
v
You replace a removed hot-swap drive within 2 minutes of removal.
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 110) can be removed permanently without affecting
system reliability.
