5. Check for any obvious non-IBM alterations. Use good judgment as to the safetyof any non-IBM alterations.6. Check inside the unit for any obvious unsafe conditions, such as metal filings,contamination, water or other liquids, or signs of fire or smoke damage.7. Check for worn, frayed, or pinched cables.8. Check that the power-supply cover fasteners (screws or rivets) have not beenremoved or tampered with.Handling static-sensitive devicesAny server part containing transistors or integrated circuits (ICs) should beconsidered sensitive to electrostatic discharge (ESD), or static-sensitive. ESDdamage can occur when there is a difference in charge between objects. Protectagainst ESD damage by equalizing the charge so that the server, the part, the workmat, and the person handling the part are all at the same charge.Notes:1. Use product-specific ESD procedures when they exceed the requirements notedhere.2. Make sure that the ESD-protective devices you use have been certified (ISO9000) as fully effective.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 grounded wrist strap against your skin to eliminate static on your body.v Prevent the part from touching your clothing. Most clothing is insulative andretains a charge even when you are wearing a wrist strap.v Use the black side of a grounded work mat to provide a static-free work surface.The mat is especially useful when handling static-sensitive devices.v Select a grounding system, such as those in the following list, to provideprotection that meets the specific service requirement.Note: The use of a grounding system is desirable but not required to protectagainst electrostatic discharge damage.– Attach the ESD ground clip to any frame ground, ground braid, or green-wireground.– Use an ESD common ground or reference point when working on adouble-insulated or battery-operated system. You can use coax orconnector-outside shells on these systems.– Use the round ground-prong of the ac plug on ac-operated servers.Grounding requirementsElectrical grounding of the server is required for operator safety and correct systemfunction. Proper grounding of the electrical outlet can be verified by a certifiedelectrician.148 Hardware Maintenance Manual: xSeries 360 Type 8686
