• To use an ESD wristband , attach the clip of the ESD wristband (strap) to any bare
(unpainted) metal on the PFC500/E chassis; 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.
IMPORTANT: 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 CRU, touch a bare (unpainted) metal surface of the cabinet or
chassis.
• Before removing any CRU from its antistatic bag, place one hand firmly on a bare
metal surface of the chassis, and at the same time, pick up the CRU while it is still
sealed in the antistatic bag. Once you have done this, do not move around the room
or contact other furnishings, personnel, or surfaces until you have installed the
CRU.
• When you remove a CRU 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 CRU,
first place the CRU back in the antistatic bag. When you are ready again to install
the CRU, repeat these procedures.
Precautions when removing, installing, or storing CRUs
Use the precautions listed below when you remove, handle, or store CRUs.
• Do not remove a faulty CRU until you have a replacement available.
• Handle a CRU only when using an ESD wristband as follows: attach the clip of the
ESD wristband to the ESD bracket or bare metal on the PFC 500/E chassis, and put
the wristband around your wrist with the metal button against your skin.
• Handle CRUs gently. A sudden jar, drop, or vibration can permanently damage a
CRU.
• Never use excessive force to remove or install a CRU.
• Store a CRU in the anti-static bag and specially designed shipping container in
which you received it. Use that container if you need to return the CRU for repair.
• Maintain the location where you store CRUs within the limits specified in
Appendix A.
