Chapter 3 Installing the Cisco VG224 Voice Gateway

Site Log

•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, 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 occurs when electronic components are improperly handled; it 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 clip to the ESD-strap connection jack (to the left of the power switch on the rear of the chassis) or to an unpainted chassis frame surface.

Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohm (Mohm).

We recommend that you maintain a Site Log to record all actions relevant to the system. Site Log entries might include the following:

•Installation—Print a copy of the Installation Checklist and insert it into the Site Log.

•Upgrades and maintenance—Use the Site Log to record ongoing maintenance and expansion history. Update the Site Log to reflect the following:

–Configuration changes

–Maintenance schedules, requirements, and procedures performed

–Comments, notes, and problems

–Changes and updates to Cisco IOS software
