4. Remove the cover.
5. Check for any obvious non-IBM alterations. Use good judgment as to the safety
6. Check inside the unit for any obvious unsafe conditions, such as metal filings,
7. Check for worn, frayed, or pinched cables.
8. Check that the power-supply cover fasteners (screws or rivets) have not been
Handling static-sensitive devices
Any server part containing transistors or integrated circuits (ICs) should be
considered sensitive to electrostatic discharge (ESD), or static-sensitive. ESD
damage can occur when there is a difference in charge between objects. Protect
against ESD damage by equalizing the charge so that the server, 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
2. Make sure that the ESD-protective devices you use have been certified (ISO
When handling static-sensitive parts:
v Keep the parts in protective packages until they are inserted into the product.
v Avoid contact with other people.
v Wear a properly grounded wrist strap against your skin to help eliminate static
v Prevent the part from touching your clothing. Most clothing is insulative and
v Use the black side of a grounded work mat to provide a static-free work surface.
v Select a grounding system, such as those in the following list, to provide
Grounding requirements
Electrical grounding of the server is required for operator safety and correct system
function. Proper grounding of the electrical outlet can be verified by a certified
electrician.

protection that meets the specific service requirement.
Note: The use of a grounding system is desirable but not required to protect
against electrostatic discharge 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 servers.
