If a tester is available, test the wristband.
•
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 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.
•
Before touching any unit, touch a bare (unpainted) metal surface of the cabinet/rack or enclosure.
•
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.
•
When you remove a unit from the antistatic bag, avoid touching any electronic components and
circuits on it.
•
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.
