General Information
Before You Begin
Before proceeding with the disassembly procedure, make sure that you do the following:
1. Turn off the power to the system and all peripherals.
2. Unplug the AC adapter and all power and signal cables from the system.
3. Open the system according to the instruction.
4. Follow the ESD precautions described in this section when handling a server component.
5. Remove any expansion board(s) or peripheral(s) that block access to the DIMM socket or other
components connector.
ESD Precautions
Electrostatic discharge (ESD) can damage the processors, motherboard, disk drives, expansion boards,
or other components. Always observe the following precautions before you exchange a server component:
1. Do not remove a component from its protective packaging until you are ready to install it.
2. Wear a wrist grounding strap and attach it to a metal part of the server before handling components.
If a wrist strap is not available, maintain contact with the server throughout any procedure requiring
ESD protection.
Post-installation instructions
Observe the following after installing a server component:
1. See to it that all components are installed according to the describled step-by-step instructions.
2. Reinstall any expansion board(s) or periphera(s) that you have previously removed.
3. Reinstall the air baffle.
4. Reinstall the chassis panels.
5. Connect the necessary cables.
6. Turn on the system.
CAUTION: After completing the component upgrade/replacement procedures, do not forget to reinstall the
air baffle before replacing the chassis panels. Failure to do so will reduce the system’s cooling
efficiency which can adversely affect performance or cause damage due to overheating.
