Static Electricity Precautions; Identifying Controller Or Expansion Module Faults - R/Evolution 2000 Series Troubleshooting Manual

Static Electricity Precautions

To prevent damaging a FRU, make sure you follow these static electricity
precautions:
Remove plastic, vinyl, and foam from the work area.
■
Wear an antistatic wrist strap, attached to a ground.
■
Before handling a FRU, discharge any static electricity by touching a ground
■
surface.
Do not remove a FRU from its antistatic protective bag until you are ready to
■
install it.
When removing a FRU from a controller enclosure, immediately place the FRU
■
in an antistatic bag and in antistatic packaging.
Handle a FRU only by its edges and avoid touching the circuitry.
■
Do not slide a FRU over any surface.
■
Limit body movement (which builds up static electricity) during FRU
■
installation.

Identifying Controller or Expansion Module Faults

The controller and expansion modules contain subcomponents that require the
replacement of the entire FRU should they fail. Each controller and expansion
module contains LEDs that can be used to identify a fault. Additionally, you can use
RAIDar to locate and isolate controller and expansion module faults. (See
"Troubleshooting Using RAIDar" on page 35.)
Note –
The controller module is often the FRU reporting faults, but is not always the FRU
where the fault is occurring.
