Preparing For Service; Removing And Replacing Components - Sun Microsystems StorEdge T3 Installation, Operation And Service Manual

5.1

Preparing for Service

Follow these procedures to help prevent damaging FRUs:
Before handling a FRU, discharge any static electric charge by touching a ground
surface.
Wear a grounding wrist strip.
Do not remove a FRU from its antistatic protective bag until it is ready for
installation.
When removing a FRU from the disk tray, immediately place it in an antistatic
bag and packaging.
Handle a FRU only by its edges and avoid touching the circuitry.
Do not slide a FRU over any surface.
Avoid having plastic, vinyl, and foam in the work area.
Limit body movement (which builds up static electricity) during FRU installation.
Caution – Although the disk tray will remain operational for up to 30 minutes with
a FRU removed, replace a failed FRU as soon as you have removed it from the disk
tray.
