This document describes site requirements and equipment needed to install your Cisco IAD2801. It includes the following sections:
•Required Tools and Equipment for Installation and Maintenance
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Follow these guidelines to ensure general safety:
•Keep the chassis area clear and dust-free during and after installation.
•If you remove the chassis cover, put it in a safe place.
•Keep tools and chassis components away from walk areas.
•Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll up your sleeves.
•Wear safety glasses when working under conditions that might be hazardous to your eyes.
•Do not perform any action that creates a hazard to people or makes the equipment unsafe.
Note For safety information you must know before working on your Cisco router, see the Cisco 2800 and Cisco 3800 Series Integrated Services Routers Regulatory Compliance and Safety Information document.
Warning Read the installation instructions before connecting the system to the power source. Statement 1004
Follow these guidelines when working on equipment powered by electricity:
•Locate the emergency power-off switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly turn off the power.
•Disconnect all power before doing the following:
–Installing or removing a chassis
–Working near power supplies
•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.
•Do not work alone if hazardous conditions exist.
•Never assume that power is disconnected from a circuit. Always check.
•Never open the enclosure of the router's internal power supply.
•If an electrical accident occurs, proceed as follows:
–Use caution; do not become a victim yourself.
–Turn off power to the device.
–If possible, send another person to get medical aid. Otherwise, assess the victim's condition and then call for help.
–Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.
In addition, use the following guidelines when working with any equipment that is disconnected from a power source, but still connected to telephone wiring or other network cabling:
•Never install telephone wiring during a lightning storm.
•Never install telephone jacks in wet locations unless the jack is specifically designed for it.
•Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It can occur if electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing modules:
•Ensure that the router chassis is electrically connected to earth ground.
•Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
•If no wrist strap is available, ground yourself by touching a metal part of the chassis.
This section describes the requirements your site must meet for safe installation and operation of your router. Ensure that the site is properly prepared before beginning installation. If you are experiencing shutdowns or unusually high errors with your existing equipment, this section can also help you isolate the cause of failures and prevent future problems.
Check the power at your site to ensure that you are receiving "clean" power (free of spikes and noise). Install a power conditioner if necessary.
The AC power supply includes the following features:
•Autoselects either 110 V or 220 V operation.
•All units include a 6-foot (1.8-meter) electrical power cord. (A label near the power inlet indicates the correct voltage frequency, current draw, and power dissipation for the unit.)
Cisco IAD2801 series integrated access devices can be placed on a desktop or installed in a rack. The location of your router and the layout of your equipment rack or wiring room are extremely important considerations for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. Plan for access to both front and rear panels of the router.
When planning your site layout and equipment locations, remember the precautions described in the next section "Site Configuration," to help avoid equipment failures and reduce the possibility of environmentally caused shutdowns. If you are currently experiencing shutdowns or an unusually high number of errors with your existing equipment, these precautions may help you isolate the cause of the failures and prevent future problems.
The following precautions will help you plan an acceptable operating environment for your router and will help you avoid environmentally caused equipment failures:
•Ensure that the room where your router operates has adequate air circulation. Electrical equipment generates heat. Without adequate air circulation, ambient air temperature may not cool equipment to acceptable operating temperatures.
•Always follow ESD-prevention procedures described in the "Preventing Electrostatic Discharge Damage" section to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.
•Ensure that the chassis cover and module rear panels are secure. All empty network module slots, interface card slots, and power supply bays must have filler panels installed. The chassis is designed to allow cooling air to flow within it, through specially designed cooling slots. A chassis with uncovered openings permits air leaks, which may interrupt and reduce the flow of air across internal components.
Cisco IAD2801 series integrated access devices include brackets for use with a 19-inch rack.
Note Brackets for a 23-inch rack are not available for Cisco IAD2801 series integrated access devices.
The following information will help you plan your equipment rack configuration:
•Allow clearance around the rack for maintenance.
•Allow at least one rack unit of vertical space between routers.
•Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.
•When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated into the rack.
•Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can be found by experimenting with different configurations.
•When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the equipment by itself, if possible. Power off other equipment in the rack (and in adjacent racks) to allow the router under test a maximum of cooling air and clean power.
The sample installation checklist lists items and procedures for installing a new router. Make a copy of this checklist and mark the entries when completed. Include a copy of the checklist for each router in your Site Log (described in the next section, "Creating a Site Log").
The Site Log provides a record of all actions related to the router. Keep it in an accessible place near the chassis where anyone who performs tasks has access to it. Use the Installation Checklist to verify steps in the installation and maintenance of the router. Site Log entries might include the following information:
•Installation progress—Make a copy of the Installation Checklist and insert it into the Site Log. Make entries as each procedure is completed.
•Upgrade and maintenance procedures—Use the Site Log as a record of ongoing router maintenance and expansion history. A Site Log might include the following events:
–Installation of network modules
–Removal or replacement of network modules and other upgrades
–Configuration changes
–Maintenance schedules and requirements
–Maintenance procedures performed
–Intermittent problems
–Comments and notes
Do not unpack the router until you are ready to install it. If the final installation site will not be ready for some time, keep the chassis in its shipping container to prevent accidental damage. When you are ready to install the router, proceed with unpacking it.
The router, cables, publications, and any optional equipment you ordered may be shipped in more than one container. When you unpack the containers, check the packing list to ensure that you received all the following items:
