Handling FRUs
Handling FRUs
This section describes the precautions that you must take and the
general procedures you must follow when removing, installing, and
storing any field replaceable unit (FRU).
Front bezels or EMI shields should always be attached and each
compartment should contain a FRU or filler panel to ensure EMI
compliance and proper air flow over the FRUs.
You should not remove a faulty FRU until you have a replacement
available.
When you replace or install FRUs, you can inadvertently damage the
sensitive electronic circuits in the equipment by simply touching
them. Electrostatic charge that has accumulated on your body
discharges through the circuits. If the air in the work area is very dry,
running a humidifier in the work area will help decrease the risk of
ESD damage. Follow the procedures below to prevent damage to the
equipment.
Read and understand the following instructions:
1. Provide enough room to work on the equipment. Clear the work
site of any unnecessary materials or materials that naturally build
up electrostatic charge, such as foam packaging, foam cups,
cellophane wrappers, and similar items.
2. Do not remove replacement or upgrade FRUs from their antistatic
packaging until you are ready to install them.
3. Before you service a system, gather together the ESD kit and all
other materials you will need. Once servicing begins, avoid
moving away from the work site; otherwise, you may build up an
electrostatic charge.
4. To use and ESD wristband, attach the clip to any bare (unpainted)
metal on the storage system; then put the wristband around your
wrist with the metal button against your skin.
5. 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.
