◆If an emergency arises and the ESD kit is not available, follow the procedures in
Emergency procedures (without an ESD kit) on page 4
◆Use the ESD wristband that is supplied with the server.

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 enclosure.
◆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
◆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.
Removing, installing, or storing CRUs
Use the following precautions when removing, handling, or storing CRUs:
◆Do not remove a faulty CRU from the cabinet until you have the replacement available.
◆Handle a CRU only when wearing an ESD wristband (strap).
•Attach the clip of the ESD wristband to the ESD bracket or bare metal on a cabinet
enclosure.
•Wrap the ESD wristband around your wrist with the metal button against your skin.
◆Handle a CRU gently. A sudden jar, drop, or vibration can permanently damage some
CRUs.
◆Never use excessive force to remove or install a CRU. Take time to read the instructions
carefully.
