Preparing to Install the
Cisco Optical Regenerator
This chapter describes the tasks you must perform before you begin to install the Cisco Optical Regenerator and includes the following sections:
Before beginning any of the procedures in this document:
- Review electrical and telephonic safety and ESD-prevention guidelines to help you avoid injury to yourself or damage to the equipment.
- Ensure that your equipment configuration meets the minimum requirements for the installation you will perform, and that you have all the parts and tools you need.
The following guidelines will help to ensure your safety and protect the equipment. This list does not include all potentially hazardous situations, so be alert.
- Install your Cisco Optical Regenerator in compliance with national and local electrical codes: in the United States, National Fire Protection Association (NFPA) 70, United States National Electrical Code; in Canada, Canadian Electrical Code, part I, CSA C22.1; in other countries, International Electrotechnical Commission (IEC) 364, part 1 through part 7.
- 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 regenerator has adequate air circulation.
- Review the safety warnings listed in the Regulatory Compliance and Safety Information for the Cisco Optical Regenerator publication before installing, configuring, or maintaining the regenerator.
- Never attempt to lift an object that might be too heavy for you to lift by yourself.
- Always disconnect the power source and unplug all power cables before working on the regenerator.
- Keep the work area clear and dust free during and after installation.
- Keep tools and the regenerator away from walk areas.
- Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught in the regenerator. Tuck your tie or scarf and fasten your sleeves.
- Use the Cisco Optical Regenerator in accordance with its marked electrical ratings and product usage instructions to ensure safe operation.
- Do not work alone if potentially hazardous conditions exist.
- The regenerator is shipped with a three-wire electrical grounding-type plug that will only fit into a grounding-type power outlet. This is a safety feature. Ground the equipment in accordance with local and national electrical codes.
- A Cisco Optical Regenerator configured with a DC-input requires an external DC circuit breaker for each input DC power source. This circuit breaker should protect against short-circuit and overcurrent faults in accordance with United States National electrical Code NFPA 70 (United States), Canadian electrical code, part I, CSA C22.1 (Canada) and IEC 364 (other countries).
- Only a DC power source that complies with the safety extra-low voltage (SELV) requirements in UL 1950, CSA-C22.2 No. 950, EN60950, ACA TS001, AS/NZS 3260, IEC60950 can be connected to the Cisco Optical Regenerator with a DC-input.
- A Cisco Optical Regenerator configured with a DC-input will have a readily accessible disconnect device incorporated for fixed wiring.
Follow these basic guidelines when working with any electrical equipment:
- Before beginning any procedures on the Cisco Optical Regenerator, locate the emergency power-off switch for the room in which you are working.
- If an electrical accident occurs, proceed as follows:
- Use caution; do not become a victim yourself. Disconnect power to the system.
- If possible, send another person to get medical aid; otherwise, assess the condition of the victim, then call for help.
- Determine if the person needs rescue breathing or external cardiac compressions, then take appropriate action.
- Disconnect all power and external cables before installing or removing a regenerator.
- Always check to see that power has been disconnected from a circuit.
- Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
- Never install equipment that appears damaged.
- Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
In addition, use the following guidelines when working with any equipment that is disconnected from a power source, but still connected to telephone or network wiring:
Electrostatic discharge damage, which can occur when electronic boards or components are handled improperly, can result in complete or intermittent failures.
Following are guidelines for preventing ESD damage:
- Always use an ESD-preventive wrist strap or ankle strap and ensure that it makes good skin contact.
- When removing or installing a component, connect the equipment end of a ground strap to one of the two ESD ground sockets located on the front sides of the upper card cage or to a bare metal surface on the frame.
- The wrist strap only protects the component from ESD voltages on the body; ESD voltages on clothing can still cause damage.
- Always follow the ESD-prevention procedures described in the section "Installation Checklist" earlier in this chapter to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.
 | Caution
Be sure to check the resistance value of the antistatic strap periodically. The measurement should be between 1 and 10 megohms. |
This section describes the requirements your site must meet for safe installation and operation of your regenerator. Ensure that your site is properly prepared before beginning installation.
The location and the layout of your equipment rack are extremely important for proper system operation when you mount the regenerator in the rack. Equipment placed too close together can cause inadequate ventilation, and can cause system malfunctions and shutdowns.
Be sure to plan your site layout and equipment locations 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 may help you isolate the cause of failures and prevent future problems.
The following tips will help you plan a well-ventilated equipment rack configuration:
Figure 2-1 shows the location of intake or exhaust ports, and fans on the regenerator.

| Caution
Do not place anything on top of the Cisco Optical Regenerator that weighs more than 10 pounds (4.5 kilograms (kg)). More weight on top could damage the regenerator. |
Keep a site log to record of all actions related to the Cisco Optical Regenerator near the chassis where anyone who installs or configures the regenerator can access it. Use the installation checklist (see the following section, "Inspecting the System") to verify installation. Site log entries might include the following:
- Background information---Include the IP addresses of all devices on the network.
- Installation progress---Make a copy of the installation checklist and insert it into the site log. Make entries on the checklist as you complete each procedure.
- Maintenance procedures---Use the site log as a record of ongoing system configuration and expansion. Each time a procedure is performed on the regenerator, update the site log to reflect the following:
- Configuration changes
- Changes and updates to Cisco IOS software
- Maintenance schedules and requirements
- Intermittent problems
- Related comments and notes
Do not unpack the Cisco Optical Regenerator until you are ready to install it. If the final installation site will not be ready for some time, keep the regenerator in its shipping container to prevent accidental damage. Unpack the regenerator when you have determined where you want to install it.
The Cisco Optical Regenerator, cables, Cisco Connection Documentation CD-ROM or printed publications, 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:
Inspect all items for shipping damage. If anything appears to be damaged, or if you encounter problems when installing or configuring your system, contact a customer service representative.
You will need the following are the tools to install the Cisco Optical Regenerator:
- Phillips screwdriver or 3/16 flat blade screwdriver
- Wire cutters
- Wire strippers
- Cable accessory kit, which includes the following items:
- Single-mode long-reach simplex cables with SC connectors (not in the kit)
Note Single-mode long-reach simplex cables with SC connectors are available from the following cable vendors: AMP, Anixter, AT&T, Red-Hawk, and Siemens. These cables are not available from Cisco Systems.
The installation checklist lists the procedures for initial hardware installation of a new Cisco Optical Regenerator. Mark the entries as you complete each procedure. Make a copy of this checklist for each regenerator in your site log.
