EMC Avamar Data Store Gen4T Customer Service Guide

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.
Note
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 CRU, touch a bare (unpainted) metal surface of the enclosure.
l
Before removing any CRU from its antistatic bag, place one hand firmly on a bare
l
metal surface of the enclosure, 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
l
components and circuits on it.
If you must move around the room or touch other surfaces before installing a CRU,
l
first place the CRU back in the antistatic bag. When you are ready again to install the
CRU, repeat these procedures.
Use the following precautions when you remove, handle, or store CRUs:
Do not remove a CRU from the cabinet until you have the replacement available.
l
Handle a CRU only when wearing a properly attached ESD wristband:
l
Attach the clip of the ESD wristband to the ESD bracket or to a bare metal portion of
the CRU's enclosure.
Secure the 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
l
CRUs.
The weight of some CRUs is not evenly distributed. To prevent personal injury or
l
equipment damage when removing, installing, or handling theses CRUs, use both
hands and provide extra support at the heavy end of the CRU.
Never use excessive force to remove or install a CRU.
l
Store a CRU in the antistatic bag and the specially designed shipping container in
l
which you received it. Use this special shipping container when you need to return
the CRU.
If you need to store a CRU for a short time, make sure the temperature of the location
l
where you store CRU is within the limits specified by the CRU's Technical
Specifications.
