To use it, attach the clip of the ESD wristband (strap) to any bare (unpainted) metal on the cabinet
enclosure; then secure 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. You should follow them
only in the event of an emergency.
Before touching any FRU, touch a bare (unpainted) metal surface of the 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 contact 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.
Removing, installing, or storing FRUs
Use the following precautions when you remove, handle, or store FRUs:
Do not remove a FRU from the cabinet until you have the replacement available.
Handle a FRU only when wearing a properly attached ESD wristband:
Attach the clip of the ESD wristband to the ESD bracket or to a bare metal portion of the FRU’
s
enclosure.
Secure the wristband around your wrist with the metal button against your skin.
Handle a FRU gently. A sudden jar, drop, or vibration can permanently damage some FRUs.
The weight of some FRUs is not evenly distributed. To prevent personal injury or equipment damage
when removing, installing, or handling theses FRUs, use both hands and provide extra support at the
heavy end of the FRU.
Never use excessive force to remove or install a FRU.
Store a FRU in the antistatic bag and the specially designed shipping container in which you received it.
Use this special shipping container when you need to return the FRU.
If you need to store a FRU for a short time, make sure the temperature of the location where you store
FRU is within the limits specified by the FRU’
s Technical Specifications.
Disk modules are sensitive to the extreme temperatures sometimes encountered during shipping. We
recommend that you leave a new disk modules in its shipping container and allow it to acclimate to the
installation site’
s ambient temperature for at least four hours before operating the new module in the
system.
When removing a disk module, pull the module part way out of the slot, then wait 30 seconds for the
drive to spin down before removing it.
