Handling field replaceable units (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).
Power issues and FRUs
Your storage system is designed to be powered on continuously. Most
components are hot repairable; that is, you can replace these components
while the storage 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 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
thecabinetorstoragesystem.
Before removing any FRU from its antistatic bag, place one hand
firmly on a bare metal surface of the storage system, and at the
same time, pick up the FRU while it is still sealed in the antistatic
bag.Onceyouhavedonethis,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.

Unlocking and removing the front bezel
To remove the front bezel, do the following:
1. Unlock the front bezel by turning the key at the front of the
enclosure counterclockwise (Figure 1).
2. Press the buttons on the front of the bezel and pull the bezel toward
you.

Removing a failed power supply module
Make sure the second power supply is working properly before
removing the faulty power supply module. Verify that its power LED
is green with no amber fault light.

Installing a power supply module
To install a power supply module from the front of the cabinet, do the
following:
1. Align the power supplymodulewiththeenclosureslot(Figure3).
2. Make sure the locking latch bar is fully open before installing the
power supply.
3. Carefully push the power supply module into the slot, fully seating
it (Figure 3).
4. Make sure the latch locks into place to secure the power supply in
the enclosure.
5. Secure the locking latch bar to the enclosure and tighten the captive
screw.

Installing and locking the front bezel
1. While holding the front bezel by its edges, engage it with the two
brackets on the front of the enclosure (Figure 4).
2. Push the bezel in until you feel it latch in place. Pull back on the
bezel slightly tomakesureitissecured(Figure4).

Verifying the operation of a new or replaced part using Navisphere
Manager
1. Start Navisphere® Manager for the storage system by entering the
IP address in a browser window.
2. IntheNavisphereManagerStorage tree, locate the icon for the
storage system in which you installed or replaced the part, expand
the storage-system icon, and select the Physical icon.
3. Expand the enclosure in which you installed or replaced the part,
and navigate to the part.
4. Verify that the part is in the enclosure and that it is not faulted.

Returning the failed part
Ship the failed part to your service provider. To do this, follow the
instructions in the return kit that was sent with the replacement part.
