PRELIMINARY
Handling Field-Replaceable
Units (FRU)
This section describes the precautions that you must take and the general procedures you
must follow when removing, installing, and storing disk modules, fans, memory cards,
battery-backed cache cards, the storage processor assembly, or any other field replaceable
unit (FRU).
Power issues and FRUs
SSR212PP-Series storage systems are designed to be powered up continually. Disks and
power supplies are hot repairable; that is, you can replace faulty units while the system is
running. Front bezels 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:
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.
Do not remove replacement or upgrade FRUs from their antistatic packaging until you
are ready to install them.
Before you service a storage 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.
An ESD wristband is supplied with your storage system. To use it, attach the clip of
the ESD wristband (strap) to any bare (unpainted) metal on the storage system; then
put the wristband around your wrist with the metal button against your skin.
Use the ESD kit when handling any FRU. If an ESD kit is not available, follow the
procedures in the "Without an ESD Kit" section.
