Preparing for the Installation

---

Before you install the Cisco Remote-PHY solution, consider the following:

• Power and cabling requirements that must be in place at your installation sites
• Equipment required to install the Cisco Remote-PHY solution
• Environmental conditions your installation site must meet to maintain normal operation

Note	Do not unpack the equipment until you are ready to install it. Keep the equipment in the shipping container to prevent accidental damage until you determine an installation site.

This section provides information on:

General Safety Guidelines

When you install a component, observe all caution and warning statements mentioned in this section.

The following guidelines will help ensure your safety and protect the equipment. However, these guidelines may not cover all potentially hazardous situations you may encounter during system installation, so be alert.

• Install your product in compliance with the national and local electrical codes. In the United States, this means the National Fire Protection Association (NFPA) 70, United States National Electrical Code. In Canada, Canadian Electrical Code, part I, CC22.1. In other countries, International Electrotechnical Commission (IEC) 364, part 1 through part 7.
• Review the safety warnings listed in the regulatory compliance and safety documentation before installing, configuring, or performing maintenance on the product.
• Disconnect power at the source before you install or remove a chassis.
• Do not attempt to lift an object you might find too heavy to lift safely.
• Keep the equipment area clear and as dust free as possible during and after installation.
• Keep tools and equipment components away from walk areas.
• Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught in the equipment.
• Use the product in accordance with its marked electrical ratings and product usage instructions.

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030.

Electrical Equipment Guidelines

• Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.
• Disconnect all power and external cables before moving a chassis.
• Do not work alone in potentially hazardous conditions.
• Never assume that power has been disconnected from a circuit; always check.
• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
• Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage occurs when electronic cards or components are improperly handled, and can result in complete or intermittent failures. All line cards consist of a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the cards from ESD, use an antistatic strap each time you handle the modules. Handle the carriers by the edges only; never touch the cards or connector pins.

Caution

Always tighten the captive installation screws on all system components when you are installing them. These screws prevent accidental removal of the module, provide proper grounding for the system, and help to ensure that the line card connectors are properly seated in the backplane. Captive screws should be torqued to 6-8 in-lbs to ensure proper grounding and mechanical support. Never use cordless or corded drills to tighten screws; power screwdrivers and hand tools are acceptable.

Static electricity can harm delicate components inside your system. To prevent static damage, discharge static electricity from your body before you touch any of your system components. As you continue to work on your system, periodically touch an unpainted metal surface on the computer chassis.

The following guidelines can prevent ESD damage:

• Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Before removing a card from the chassis, connect the equipment end of the strap to the ESD plug at the bottom of the chassis below the power entry modules. Ensure that the chassis or rack or both have a grounding cable installed.
• Handle line cards by the faceplate and carrier edges only; avoid touching the card components or any connector pins.
• When removing a card, place the removed module component-side-up on an antistatic surface or in a static-shielding bag. If the module will be returned to the factory, immediately place it in a static-shielding bag.
• Avoid contact between the modules and clothing. The wrist-strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.
• When transporting a sensitive component, first place it an antistatic container or packaging.
• Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.

Caution

For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

Site Requirements

This section provides information about environmental, power, cabling, and mounting requirements. Ensure that you have met all of these requirements before you install your product.

Environmental Requirements for the Cisco CMC
