WarningThere is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.
General Precautions
Observe the following general precautions when using and working with your system:
Keep your 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 (TAC). For instructions on contacting TAC, see the "Obtaining Technical Assistance" section.
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; route 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 and 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 disconnecting a peripheral device from the computer.
Maintaining Safety with Electricity
Follow these guidelines when working on equipment powered by electricity:
If any of the following conditions occur, contact the Cisco Technical Assistance Center (TAC):
The power cable, extension cable, or plug is damaged.
An object has fallen into the product.
The product has been exposed to water.
The product has been dropped or damaged.
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 TAC or a local power company.
Use only approved power cables. If you have not been provided with a power cable for your computer or storage system or for any AC-powered option intended for your system, purchase a power cable that is approved for use in your country. The power cable must be 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 cable should be greater than the ratings marked on the product.
To help prevent electric shock, plug the VLAN Policy Server, components, and peripheral power cables into properly grounded electrical outlets. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a three-wire cable with properly grounded plugs.
Observe extension cable and power strip ratings. Make sure that the total ampere rating of all products plugged into the extension cable or power strip does not exceed 80% of the extension cable with the properly grounded plugs.
To help 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 delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer's electronic components, such as the microprocessor. You can discharge static electricity 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.
Note that:
Bad plant wiring can result in radio frequency interference (RFI).
Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the system, and can even create an electrical hazard by conducting power surges through lines and into the system.
To predict and remedy strong EMI, consult RFI experts.
Preparing Your Site for Installation
This section describes the requirements your site must meet for safe installation and operation of your VLAN Policy Server. Ensure that your site is properly prepared before beginning installation.
Environmental
When planning your site layout and equipment locations, keep in mind the precautions described in this section to help avoid equipment failures and reduce the possibility of environmentally caused shutdowns. If you are currently experiencing shutdowns or unusually high errors with your existing equipment, these precautions will help you isolate the cause of failures and prevent future problems.
Use the following precautions when planning the operating environment for your VLAN Policy Server.
Always follow the ESD-prevention procedures described in the "Preventing EMI" section to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.
Make sure that the chassis cover is secure. The chassis is designed to allow cooling air to flow effectively within it. 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.
Choosing a Site for Installation
WarningThis unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location.
Choose a site with a dry, clean, well-ventilated and air-conditioned area.
Choose a site that maintains an ambient temperature of 10° to 35°C (50° to 95°F).
Grounding the System
Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.
Creating a Safe Environment
Follow these guidelines to create a safe operating environment:
Keep tools and chassis components off 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 VLAN Policy Server power requirements, see "Technical Specifications."
Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Make sure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. and 240 VAC, 10A international are used on the phase conductors (all current-carrying conductors).
Cabling
Use the cables in the accessory kit to connect the VLAN Policy Server console port to a console or computer that is running a console program. In addition to the console cable, you must supply your own standard Ethernet cable to connect the VLAN Policy Server to your network. For information detailing cable requirements, see the "Network Cable Requirements" section.
A structured wiring system provides a standardized way to wire a building for all types of networks for the VLAN Policy Server to be installed. The main distribution frame links all the building's interior wiring and provides an interface connection to circuits coming from outside sources such as the local telephone company. Wiring hubs (peripherals for cabling installations) provide the connection logic unique to Fast Ethernet cables that the VLAN Policy Server uses. Unshielded twisted pair (UTP) copper wire is used to connect the VLAN Policy Server and distributes the network connections to wall jacks near each piece of network equipment.
Precautions for Rack Mounting
Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation accompanying the rack for specific warning and/or caution statements and procedures.
Servers, storage systems, and appliances are considered to be components in a rack. Thus, component refers to any server, storage system, or appliance, as well as 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.
Ensure that proper airflow is provided to components in the rack.
