Before you begin
Before you begin this maintenance activity, refer to the component handling instructions.
You should also review the entire procedure prior to beginning any maintenance activity
on the system.
Handling replaceable units
This section describes the precautions that you must take and the general procedures
that you must follow when removing, installing, and storing any replaceable unit. The
procedures in this section apply to replaceable unit handling during hardware upgrades
as well as during general replacement.
Avoiding electrostatic discharge (ESD) damage
When replacing or installing hardware units, 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.
Read and understand the following instructions:
u
Provide enough room to work on the equipment.
u
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.
u
Do not remove replacement or upgrade units from their antistatic packaging until you
are ready to install them.
u
Gather the ESD kit and all other materials before servicing any units.
u
After servicing begins, avoid moving away from the work site; otherwise, you might
build up an electrostatic charge.
u
Use the ESD kit when handling any units.
u
If an emergency arises and the ESD kit is not available, follow the procedures in
Emergency procedures (without an ESD kit) on page 3
u
Use the ESD wristband that is supplied with the server.
u
To use it, attach the clip of the ESD wristband (strap) to any bare (unpainted) metal
on the cabinet or enclosure, and then put the wristband around your wrist with the
metal button against your skin.
Emergency procedures (without an ESD kit)
In an emergency when an ESD kit is not available, use the following procedures to reduce
the possibility of an electrostatic discharge by ensuring that your body and the
subassembly are at the same electrostatic potential.
These procedures are not a substitute for the use of an ESD kit. Follow them only in the
event of an emergency.
u
Before touching any unit, touch a bare (unpainted) metal surface of the enclosure.
u
Before removing any unit from its antistatic bag, place one hand firmly on a bare
metal surface of the enclosure, and at the same time, pick up the unit while it is still
sealed in the antistatic bag. Once you have done this, do not move around the room
or touch other furnishings, personnel, or surfaces until you have installed the unit
u
When you remove a unit from the antistatic bag, avoid touching any electronic
components and circuits on it.
