General Precautions

•

Keep all system components away from radiators and heat sources, and do not block cooling vents.

•

Do not spill food or liquids on your system components, and never operate the product in a wet environment. If the computer gets wet, see the appropriate chapter in your troubleshooting guide or contact the Cisco Technical Assistance Center. For instructions on contacting the Technical Assistance Center, see Obtaining Technical Assistance.

•

Do not push any objects into the openings of your system components. Doing so can cause fire or electric shock by shorting out interior components.

•

Position system cables and power cables carefully; Be sure to route the system cables and the power cable and plug so that they cannot be stepped on or tripped over. Be sure that nothing rests on your system component cables or power cable.

•

Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications. Always follow your local/national wiring rules.

•

To help avoid possible damage to the system board, wait 5 seconds after turning off the system before removing a component from the system board or before disconnecting a peripheral device from the computer.

Maintaining Safety with Electricity

•

If any of the following conditions occur contact the Cisco Technical Assistance Center:

–

The appliance does not operate correctly when you follow the operating instructions.

•

Use the correct external power source. Operate the appliance 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 power company.

•

Use only approved power cables. An approved power cable arrived with your appliance and is intended for use with your system (approved for use in your country, based on the shipping location). If you must purchase an additional power cable, ensure that it is rated for the appliance and for the voltage and the specific current that are marked on the appliance's electrical ratings label. The voltage and current rating for the cable should be greater than the ratings that are marked on the appliance.

•

To prevent electric shock, plug the appliance components and peripheral power cables into properly grounded electrical outlets. These cables are equipped with three-prong plugs to ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable.

•

To protect your system and components from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptable power supply (UPS).

•

Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications. Always follow your local and national wiring rules.

Protecting Against Electrostatic Discharge

Static electricity can harm the delicate components inside of your computer. To prevent static damage, discharge static electricity from your body before you touch any electronic components on your computer, such as the microprocessor. You can do so by touching an unpainted metal surface on the computer chassis.

As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have accumulated.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

•

When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component in your computer. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.

•

When transporting a sensitive component, first place it in an antistatic container or packaging.

•

Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.

Preventing EMI

When you run wires for any significant distance in an electromagnetic field, electromagnetic interference (EMI) can occur between the field and the signals on the wires.

Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the system and can create an electrical hazard by conducting power surges through lines and into the system.

Be aware that improper plant wiring can result in radio frequency interference (RFI).

Preparing Your Site for Installation

This section describes the site requirements for safe installation and operation of your appliance. Ensure that your site is properly prepared before beginning installation.

Environmental

When planning your site layout and equipment locations, follow the precautions described in this section to help avoid equipment failures and reduce the possibility of environmentally caused shutdowns. If you experience shutdowns or unusually high errors with your existing equipment, these precautions will help you to isolate the cause of the failures and prevent future problems.

Use the following precautions when planning the operating environment for your appliance:

•

Always follow the ESD-prevention procedures described in Preventing EMI, to avoid damage to the appliance. Damage from static discharge can cause immediate or intermittent equipment failure.

•

Make sure that the chassis cover is secure. An open chassis allows air leaks, which could interrupt and redirect the flow of cooling air from internal components.

•

Electrical equipment generates heat. Ambient air temperature might not be adequate to cool equipment to acceptable operating temperatures without adequate circulation. Make sure that the room in which you operate has adequate air circulation.

•

Install the appliance in a restricted access area, where access can be gained only by service personnel through the use of a special tool, lock and key, or other means of security.

•

Choose a site that maintains an ambient temperature of 10� to 35�C (50� to 95�F).

•

Keep tools and chassis components off of the floor and away from foot traffic.

•

Clear the area of possible hazards, such as moist floors, ungrounded power extension cables, and missing safety grounds.

•

Keep the area around the chassis free from dust and foreign conductive material (such as metal flakes from nearby construction activity).

AC Power

Ensure that the plug-socket combination is accessible at all times because it serves as the main disconnecting device. For the Guard and the Detector power requirements, see Connecting the Appliance.

Cabling

Use the cables in the accessory kit to connect the appliance console port to a console or computer that is running a console program. In addition to using the console cable, use the provided standard Ethernet cable to connect the appliance to your network.

Precautions for Rack-Mounting

Observe the following precautions for rack stability and safety. Also, for specific warning and caution statements and procedures, refer to the rack installation documentation that accompanied the rack.

Note The term "component" refers to any server, storage system, or appliance, and to various peripherals or supporting hardware.

•

Do not move large racks by yourself. Due to the height and weight of the rack, a minimum of two people are needed to accomplish this task.

•

Ensure that the rack is level and stable before extending a component from the rack.

•

Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80 percent of the branch circuit rating.

•

Do not step on or stand on any system or component when servicing other systems and components in a rack.

•

This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

•

When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

•

If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.
