Servicing a DAE2P/DAE3P
◆ Use the ESD kit when handling any FRU. If an emergency arises
and the ESD kit is not available, follow the procedures in the
Emergency Procedures (Without an ESD Kit) section.
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 FRU, touch a bare (unpainted) metal surface
of the cabinet or enclosure.
◆ Before removing any FRU from its antistatic bag, place one hand
firmly on a bare metal surface of the enclosure, and at the same
time, pick up the FRU 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 FRU.
◆ When you remove a FRU 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 FRU, first place the FRU back in the antistatic bag.
When you are ready again to install the FRU, repeat these
procedures.
Precautions when
removing, installing,
or storing FRUs
Use the precautions listed below when you remove, handle, or store
FRUs:
◆ Do not remove a faulty FRU until you have a replacement
available.
◆ Handle a FRU only when using an ESD wristband. Attach the clip
of the ESD wristband to the ESD bracket or bare metal on the
enclosure, and put the wristband around your wrist with the
metal button against your skin.
◆ Handle FRUs gently. A sudden jar, drop, or vibration can
permanently damage a FRU and may not be immediately
evident. Never place a FRU on a hard surface such as an
unpadded cart, floor, or desktop, or stacked on top of another
FRU.
