This chapter describes the procedures for replacing the controller, cache module,
external cache battery (ECB), gigabit link module (GLM), power verification and
addressing (PVA) module, I/O module, PCMCIA card, DIMMs, fibre cable or hub,
and a failed storageset member. Additionally, there are procedures for shutting

Electrostatic Discharge
Electrostatic discharge (ESD) is a common problem and may cause data loss,
system down time, and other problems. The most common source of static
electricity is the movement of people in contact with carpets and clothing. Low
humidity also increases the amount of static electricity. You must discharge all
static electricity prior to touching electronic equipment. Follow the precautions in
Electrostatic Discharge Precautions given in the Preface whenever you are
replacing any component.
