If an emergency arises and the ESD kit is not available, follow the procedures in
Emergency Procedures (without an ESD kit).
Emergency procedures (without an ESD kit)
In an emergency when an ESD kit is not available, use the following precautions to
reduce the possibility of an electrostatic discharge by ensuring that your body and the
subassembly are at the same electrostatic potential.
NOTICE
These precautions are not a substitute for the use of an ESD kit. Follow them only in
the event of an emergency.
l
Before touching any unit, touch a bare (unpainted) metal surface of the cabinet/
rack or enclosure.
l
Before removing any unit from its antistatic bag, place one hand firmly on a bare
metal surface of the cabinet/rack or 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.
l
When you remove a unit from the antistatic bag, avoid touching any electronic
components and circuits on it.
l
If you must move around the room or touch other surfaces before installing a unit,
first place the unit back in the antistatic bag. When you are ready again to install
the unit, repeat these procedures.
Hardware acclimation times
Systems and components must acclimate to the operating environment before
applying power. This requires the unpackaged system or component to reside in the
operating environment for up to 16 hours in order to thermally stabilize and prevent
condensation.
Refer to the table, Table 1 on page 5, to determine the precise amount of
stabilization time required.
