General information for removing and installing CRUs
This section describes precautions you must take and general procedures you must
follow when removing, installing, or storing CRUs. The procedures in this section apply to
CRU handling during general replacement.
Avoiding Electrostatic Discharge (ESD) damage
When replacing or installing CRUs, you can inadvertently damage the sensitive electronic
circuits in the equipment by simply touching them. Electrostatic charge that has
accumulated on your body discharges through the circuits. If the air in the work area is
very dry, running a humidifier in the work area helps decrease the risk of ESD damage.
You must use the following procedures to prevent damage to the equipment, so read the
following instructions carefully.
l
Provide enough room to work on the equipment. Clear the work site of any
unnecessary materials or materials that naturally build up electrostatic charge, such
as foam packaging, foam cups, cellophane wrappers, and similar items.
l
Do not remove replacement or upgrade CRUs from their antistatic packaging until you
are ready to install them.
l
Gather the ESD kit and all other materials you will need before you service a
component. Once servicing begins, you should avoid moving away from the work
site; otherwise, you may build up an electrostatic charge.
l
Use the ESD kit when handling any CRU.
If an emergency arises and the ESD kit is not available, follow the procedures in the
section
Emergency procedures (without an ESD kit) on page 14 .
l
Use the ESD wristband that is supplied with your system.
To use it, attach the clip of the ESD wristband (strap) to any bare (unpainted) metal
on the cabinet enclosure; then secure the wristband around your wrist with the metal
button against your skin.
