General Safety

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 ONS 15104 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 Cisco ONS 15104 has adequate air circulation.

• Review the safety warnings listed in the Regulatory Compliance and Safety Information for the Cisco ONS 15104 publication before installing, configuring, or maintaining the
  Cisco ONS 15104.

• 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
  Cisco ONS 15104.

• Keep the work area clear and dust free during and after installation.

• Keep tools and the Cisco ONS 15104 away from walk areas.

• Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught in the Cisco ONS 15104. Tuck your tie or scarf and fasten your sleeves.

• Use the Cisco ONS 15104 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 Cisco ONS 15104 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 ONS 15104 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, IEC 60950 can be connected to the Cisco ONS 15104 with a DC-input.

• A Cisco ONS 15104 configured with a DC-input will have a readily accessible disconnect device incorporated for fixed wiring.

Safety with Electricity

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures on the Cisco ONS 15104, 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 Cisco ONS 15104.

• 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:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

• Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

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" 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.

General Site Requirements

This section describes the requirements your site must meet for safe installation and operation of your Cisco ONS 15104. 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 Cisco ONS 15104 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.

Configuring Equipment Racks

The following tips will help you plan a well-ventilated equipment rack configuration:

• Remember that each unit generates heat. To ensure that enclosed racks have adequate ventilation, each enclosed rack must have louvered sides and a fan to provide cooling air.

• 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.

• When mounting a Cisco ONS 15104 in an open rack, ensure that the rack frame does not block the intake or exhaust ports.

Figure 2-1 shows the location of intake or exhaust ports, and fans on the Cisco ONS 15104.

• You can install baffles to help isolate exhaust air from intake air. This also helps to draw cooling air through the rack. The best placement of the baffles depends on the air flow patterns in the rack, which you can find by experimenting with different arrangements.

• When you mount the Cisco ONS 15104 in a rack, be sure to allow clearance space between the rack and the wall for air flow generated by the six fans along the back.

Caution Do not place anything on top of the Cisco ONS 15104 that weighs more than 10 pounds (4.5 kilograms [kg]). More weight on top could damage the Cisco ONS 15104.

Creating a Site Log

Keep a site log to record of all actions related to the Cisco ONS 15104 near the chassis where anyone who installs or configures the Cisco ONS 15104 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 Cisco ONS 15104, 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
