• The product does not operate correctly when you follow the operating instructions.
• Use the correct external power source. Operate the product only from the type of power source indicated
on the electrical ratings label. If you are not sure of the type of power source required, consult the Cisco
Technical Assistance Center or a local electrician.
• Use approved power cables only. You have been provided with one or more power cables with your
chassis power supply that are intended for use in your country, based on the shipping location. Should
you need to purchase additional power cables, ensure that they are rated for the product and for the
voltage and current marked on the product’s electrical ratings label. The voltage and current rating of
the power cable should be greater than the ratings marked on the label.
• To help prevent electrical shock, plug all the power cables into properly grounded electrical outlets.
These power cables are equipped with three-prong plugs to ensure proper grounding. Do not use adapter
plugs or remove the grounding prong from a power cable.
• Observe power strip ratings. Make sure that the total current rating of all products that are plugged into
the power strip does not exceed 80 percent of the power strip rating.
• Do not modify power cables or plugs yourself. Consult with a licensed electrician or your power company
for site modifications. Always follow your local and national wiring codes.
Preventing Electrostatic Discharge Damage
To prevent ESD damage, follow these guidelines:
• Always use an ESD wrist strap and ensure that it makes maximum contact with bare skin. ESD grounding
straps are available with banana plugs, metal spring clips, or alligator clips. All switch chassis are equipped
with a banana plug connector (identified by the ground symbol next to the USB port) somewhere on the
front panel. If you have an older chassis equipped with a plastic banana plug connector, it is recommend
that you use either the supplied ESD grounding wrist strap (with a metal clip) or an ESD grounding wrist
strap equipped with an alligator clip. If you have a newer chassis that has a bare metal hole as the banana
plug connector (also identified by the ground symbol next to the USB port), we recommend that you use
a personal ESD grounding strap equipped with a banana plug.
• If you choose to use the disposable ESD wrist strap supplied with most FRUs or an ESD wrist strap
equipped with an alligator clip, you must attach the system ground lug to the chassis in order to provide
a proper grounding point for the ESD wrist strap.
• If your chassis does not have the system ground attached, you must install the system ground. See
Establishing the System Ground, on page 45
for installation instructions and locations of the chassis
system ground pads.
Attaching the ESD Wrist Strap
After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:
Procedure
Step 1
Secure the ESD wrist strap equipped with an alligator clip to your bare skin.
