Chapter 7. Gaining Access to System Components
This chapter describes how to gain access to major internal components so you can upgrade and service your system.
 | Warning: This is a user-serviceable system. Service and upgrade tasks should be performed by users who can follow instructions in a manual to service equipment, and can do so without harm to themselves or damage to the equipment.
|
| Warning: The system is always on when connected to AC power and the power supplies are switched on. Before opening the system, switch off both power suppliesInternal components may be at high temperatures. Allow time for them to cool before handling them.
|
| Warning: Internal components can be damaged by static electricity. Use an antistatic wrist strap connected to the bare metal of the system's chassis to protect against electrostatic discharge.
|
 | Note: “Right side” and “left side” are as seen from the front of the system.
|
Avoiding Electrostatic Discharge
Sensitive components inside the base unit can be damaged by static electricity. To protect against electrostatic discharge, take the following precautions:
Disconnect the base unit from AC power before opening the base unit.
Touch the bare metal of the base unit chassis before touching any internal components.
Handle all printed circuit boards as little as possible and only by the edges. Do not touch any gold contacts on a circuit board.
Leave new parts in their protective packaging until you install them.
Use a disposable or reusable antistatic wrist strap when servicing or upgrading the system. Once you use a disposable wrist strap, you cannot use it again.
Attach an antistatic wrist strap to any bare metal part of the base unit chassis. The metal conductor in the elastic sleeve of a reusable antistatic strap must contact bare skin.
Removing and Replacing the Top Cover
| Warning: The system is always on when connected to AC power and the power supplies are switched on. Before opening the system, switch off both power supplies.
|
| Warning: Replace the top cover/side panel before operating the system. This ensures proper airflow for cooling and reduces electromagnetic interference (EMI) emissions.
|
 | Caution: Ensure the stabilizers for the equipment rack are fully extended.
|
The top cover (rackmount system) or side panel (deskside system) allows access to most of the internal components.
To remove the top cover/side panel:
On a deskside system, lay the base unit on its right side.
On a rackmount system, disconnect all cables from the back of the unit.
On a rackmount system, at the front of the base unit, remove the screws that secure the handle brackets to the equipment rack mounting rails.
On a rackmount system, slide the base unit out of the equipment rack until it locks in the extended position.
At the back of the base unit, remove the screws that secure the top cover/side panel to the base unit.
Slide the top cover/side panel back and lift it off the base unit.
To replace the top cover/side panel:
Replace the top cover/side panel on the base unit and slide it forward until it is firmly seated.
On a rackmount system, slide the base unit into the equipment rack until it locks in the retracted position.
On a rackmount system, secure the handle brackets to the equipment rack mounting rails with the screws removed previously.
Secure the top cover to the base unit with the screws removed previously.
On a rackmount system, reconnect all cables to the back of the system.
On a deskside system, return the base unit to its upright position.
Removing and Replacing the Front Panel
| Warning: The system is always on when connected to AC power and the power supplies are switched on. Before opening the system, switch off both power supplies.
|
| Warning: Replace the front panel before operating the system. This ensures proper airflow for cooling.
|
To remove the front panel:
On a rackmount system, disconnect all cables from the back of the unit.
On a rackmount system, at the front of the base unit, remove the screws that secure the handle brackets to the equipment rack mounting rails.
On a rackmount system, pull the base unit out of the equipment rack until it locks in the extended position.
Open the disk drive cage door.
Remove the screws that secure the handle brackets (on a rackmount system) and the front panel to the sides of the base unit, and then remove the handle brackets.
Pull the front panel away from the base unit.
| Caution: Make sure you have slack in the wires connected to the Power keyswitch before pulling the front panel away from the base unit.
|
To replace the front panel:
With the disk drive cage door open, push the front panel onto the base unit.
| Caution: Make sure you do not catch or crimp the wires connected to the Power switch and the LEDs when pushing the front panel onto the base unit.
|
Close the disk drive cage door.
On a rackmount system, holding the handle brackets in place, secure the brackets and the front panel to the sides of the base unit with the screws removed previously.
On a deskside system, secure the front panel to the sides of the base unit with the screws removed previously.
On a rackmount system, push the base unit into the equipment rack until it locks in the retracted position.
On a rackmount system, secure the base unit handle brackets to the equipment rack mounting rails with the screws removed previously.
On a rackmount system, reconnect all cables to the back of the system.
