Safety Recommendations

Follow these guidelines to ensure general safety:

Keep the chassis area clear and dust-free during and after installation.

Put the removed chassis cover in a safe place.

Keep tools away from walk areas where you and others could fall over them.

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 if you are working under any conditions that might be hazardous to your eyes.

Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.


Warning   

Ultimate disposal of this product should be handled according to all national laws and regulations. (To see translated versions of this warning, refer to the appendix ".")


Maintaining Safety with Electricity

Follow these guidelines when working on equipment powered by electricity:


Warning   

Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or can weld the metal object to the terminals. (To see translated versions of this warning, refer to the appendix ".")


Locate the emergency power-OFF switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn OFF the power.

Power OFF the Director and unplug the power cord before doing the following:

Installing or removing a chassis

Working near power supplies


Warning    

Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. (To see translated versions of this warning, refer to the appendix ".")



Warning     

Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is OFF and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. (To see translated versions of this warning, refer to the appendix ".")



Warning    

When installing the unit, the ground connection must always be made first and disconnected last. (To see translated versions of this warning, refer to the appendix ".")


Do not work alone if potentially hazardous conditions exist.

Never assume that power is disconnected from a circuit. Always check.


Warning   

Read the installation instructions before you connect the system to its power source. (To see translated versions of this warning, refer to the appendix ".")


Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.

Turn OFF power to the system.

If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs when electronic components are improperly handled and can result in complete or intermittent failures.

Always follow ESD-prevention procedures when removing and replacing components. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to safely ground unwanted ESD voltages. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.


Caution   
For safety, periodically check the resistance value of the antistatic strap, which should be from 1 to 10 megohms (Mohms).

General Site Requirements

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

Site Environment

The Director can be placed on a desktop or mounted in a rack or on a wall. The location of the Director and the layout of your equipment rack or wiring room are extremely important for proper system operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause system malfunctions and shutdowns, and can make Director maintenance difficult.

When planning your site layout and equipment locations, keep in mind the precautions described in the next section, "Preventive Site Configuration," to help avoid equipment failures and reduce the possibility of environmentally caused shutdowns. If you are experiencing shutdowns or unusually high errors with your existing equipment, these precautions may help you isolate the cause of failures and prevent future problems.

Preventive Site Configuration

The following precautions will help you plan an acceptable operating environment for your Director and will help you avoid environmentally caused equipment failures:

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

Always follow the ESD-prevention procedures described in the section "Safety Recommendations" earlier in this chapter to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.

Ensure 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 may interrupt and redirect the flow of cooling air from internal components.

Configuring Equipment Racks

The following tips will help you plan an acceptable equipment rack configuration:

Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air.

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 all the way into the rack.

In an enclosed rack with a ventilation fan in the top, excessive heat generated by equipment near the bottom of the rack can be drawn upward and into the intake ports of the equipment above it in the rack. Ensure that you provide adequate ventilation for equipment at the bottom of 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 are found by experimenting with different arrangements.

Power Supply Considerations

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.


Warning   

The device is designed to work with TN power systems. (To see translated versions of this warning, refer to the appendix ".")


The Director's AC power supply includes the following features:

Autoselects either 110V or 220V operation.

All units include a 6-foot (1.8-meter) electrical power cord. (A label near the power cord indicates the correct voltage, frequency, current draw, and power dissipation for the unit.)


Warning   

This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. (To see translated versions of this warning, refer to the appendix ".")



Warning   

This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). (To see translated versions of this warning, refer to the appendix ".")


Installation Checklist

The Installation Checklist lists the procedures for initial hardware installation of a new Director. Make a copy of this checklist and mark the entries as you complete each procedure. Include a copy of the checklist for each system in your Site Log. (See the next section, "Creating a Site Log.")

Preparing to Connect to a Network

When setting up your Director, consider distance limitations and potential electromagnetic interference (EMI) as defined by the EIA.


Warning   

The Ethernet, console, and auxiliary ports contain safety extra-low voltage (SELV) circuits. (To see translated versions of this warning, refer to the appendix ".")


Ethernet Connections

The IEEE has established Ethernet as standard 802.3. The most common Ethernet implementations are as follows:

10Base2—Ethernet on thin coaxial cable, also known as thick Ethernet. The maximum segment distance is 607 feet (185 meters).

10Base5—Ethernet on thick coaxial cable, also known as thick Ethernet. The maximum segment distance is 1,640 feet (500 meters).

10BaseT—Ethernet on unshielded twisted-pair (UTP) cable. The maximum segment distance is 328 feet (100 meters). UTP cables looks like the wiring used for ordinary telephones; however, UTP cables meet certain electrical standards that telephone cables do not.

The Ethernet interface on your Director operates at speeds up to 10 Mbps.

Use the following equipment (not included) to connect to the Ethernet AUI port (DB-15):

Ethernet AUI cable connected to a transceiver.

Ethernet transceiver connected directly to the Director's AUI port.

The connection to the AUI port can be attached using either a slide-latch or jackscrew connector.

The cables and transceivers required to connect the Director to an Ethernet network are not included. To order cables and transceivers, refer to the Cisco Product Catalog or contact Cisco customer service.

Token Ring Connections

The IEEE has established Token Ring as standard 802.5. The distance limitations for the IEEE 802.5 specification indicate a maximum segment distance of 328 feet (100 meters) for UTP cabling. The distance limitation is 1,640 feet (500 meters) for shielded twisted-pair (STP) cabling.

Token Ring can operate at two different ring speeds: 4 and 16 Mbps. All devices on the ring must agree on the operating speed.

Use a Token Ring lobe cable to connect the Director to a media attachment unit (MAU). The lobe cable and MAU are not included with the Director. Refer to the section "Token Ring Port Pinouts" in the appendix "Cable Specifications" for the Token Ring port pinouts.

Console and Auxiliary Port Considerations

All Director models include an asynchronous serial console and auxiliary port. The console and auxiliary ports provide access to the Director either locally (with a console terminal) or remotely (with a modem). This section discusses important cabling information to consider before connecting a console terminal (an ASCII terminal or PC running terminal emulation software) to the console port or modem to the auxiliary port.

The main difference between the console and auxiliary ports is that the auxiliary port supports hardware flow control and the console port does not. Flow control paces the transmission of data between a sending device and a receiving device. Flow control ensures that the receiving device can absorb the data sent to it before the sending device sends more. When the buffers on the receiving device are full, a message is sent to the sending device to suspend transmission until the data in the buffers has been processed. Because the auxiliary port supports flow control, it is ideally suited for use with the high-speed transmissions of a modem. Console terminals transmit at slower speeds than modems; therefore, the console port is ideally suited for use with console terminals.

Console Port Connections

The Director includes an EIA/TIA-232 asynchronous serial console port (RJ-45). Depending on the cable and the adapter used, this port will appear as a DTE or DCE device at the end of the cable. Your Director comes with cables and adapters to connect a console terminal (an ASCII terminal or PC running terminal emulation software) to the console port. To connect an ASCII terminal to the console port, use the RJ-45 roll-over cable with the female RJ-45-to-DB-25 adapter (labeled Terminal). To connect a PC running terminal emulation software to the console port, use the RJ-45 roll-over cable with the female RJ-45-to-DB-9 adapter (labeled Terminal). The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 2 stop bits. The console port does not support hardware flow control. For detailed information about installing a console terminal, see the section "Connecting the Console Terminal and Modem" in the chapter "." See the appendix "" for cable and port pinouts.

Auxiliary Port Connections

The Director includes an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow control. Depending on the cable and the adapter used, this port will appear as a DTE or DCE device at the end of the cable. Your Director includes a cable and an adapter to connect a modem to the auxiliary port. To connect a modem to the auxiliary port, use the RJ-45 roll-over cable with the male RJ-45-to-DB-25 adapter (labeled Modem). For detailed information about connecting devices to the auxiliary port, see the section "Connecting the Console Terminal and Modem" in the chapter "." See the appendix "" for cable and port pinouts.

Inspecting the System

Do not unpack the Director 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 have determined where you want the Director installed, proceed with unpacking it.

The Director and any optional equipment you ordered might be shipped in more than one container. When you unpack each shipping container, check the packing list to ensure that you received all of the following items:
