Installing memory modules in the 9183-22X system
To install memory modules, complete the steps in this procedure.
Before you begin
See "Memory module plugging rules in the 9183-22X system" on page 17 to ensure that you follow the
rules for memory module placement.
Power off the system and place it in the service position. For instructions, see "Preparing the 9183-22X
system to remove and replace internal parts" on page 97.
Procedure
1. Attach the electrostatic discharge (ESD) wrist strap.
The ESD wrist strap must be connected to an unpainted metal surface until the service procedure is
completed, and if applicable, until the service access cover is replaced.
Attention:
• Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD
jack, or to an unpainted metal surface of your hardware to prevent the electrostatic
discharge from damaging your hardware.
• When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap
is used for static control. It does not increase or decrease your risk of receiving electric
shock when using or working on electrical equipment.
• If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging
and installing or replacing hardware, touch an unpainted metal surface of the system for a
minimum of 5 seconds. If at any point in this service process you move away from the
system, it is important to again discharge yourself by touching an unpainted metal surface
for at least 5 seconds before you continue with the service process.
2. Lift the air baffle (A) straight up as shown in the following figure.
Place the air baffle on a clean area.
