Server Options - 9306 Handling Electrostatic-Sensitive Devices
Applicable to: World-Wide
Handling Electrostatic Discharge-Sensitive Devices:
Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge.
Notes:
1. Use product-specific ESD procedures when they exceed the requirements noted here.
2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.
When handling ESD-sensitive parts:
Keep the parts in protective packages until they are inserted into the product.
Avoid contact with other people.
Wear a grounded wrist strap against your skin to eliminate static on your body.
Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap.
Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices.
Select a grounding system, such as those listed below, to provide protection that meets the specific service requirement.
Note:
The use of a grounding system is desirable but not required to protect against ESD damage.
- Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.
- Use an ESD common ground or reference point when working on a double-insulated or battery-operated system. You can use coax or connector-outside shells on these systems.
- Use the round ground-prong of the AC plug on AC-operated computers.
Grounding Requirements:
Electrical grounding of the PC Server Rack and computers is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
Powering Off The Rack:
Before performing service on the rack, follow this procedure to prevent personal injury and to avoid damaging the rack and the installed servers.
To power-off the PC Server Rack:
1. Shut down and power-off all installed servers.
2. Open the rear door of the PC Server Rack cabinet.
3. Power-off the server selector unit. The power switch for the server selector unit is located in the upper right corner of the rear of the server selector unit.
4. Disconnect power from the PC Server Rack.
- If the rack is plugged into a wall-mounted power supply, disconnect the power cord plug from the wall socket.
- If the power cord is wired directly into the installed location's power supply, open the rear door of the rack cabinet and disconnect the power plug from the base of the power distribution unit.
