Preventing Esd - Cisco Catalyst 8500 Series Regulatory Compliance And Safety Information Manual

Using Redundant Power
If your system includes an optional redundant (second) power supply, connect each of the two power
supplies to different input power sources. Failure to do so makes the system susceptible to total power
failure in the event that one of the power supplies fails.

Preventing ESD

Electrostatic discharge (ESD) damage occurs when electronic cards or components are mishandled and
can result in complete or intermittent failures. Note the following guidelines before you install or service
the system:
•
•
•
•
For safety, periodically check the resistance value of the antistatic strap. The measurement should be
Note
between 1 and 10 megohms (Mohms).
Installing and Servicing the System
Follow these guidelines when installing and servicing the system:

78-14229-02
Always wear an ESD-preventive wrist or ankle strap when handling electronic components. Connect
one end of the strap to an ESD jack or an unpainted metal component on the system (such as a
captive installation screw).
Handle cards by the faceplates and edges only; avoid touching the printed circuit board and
connector pins.
Place any removed component on an antistatic surface or in a static shielding bag.
Avoid contact between the cards and clothing. The wrist strap only protects the card from ESD
voltages on the body; ESD voltages on clothing can still cause damage.
Disconnect all power and external cables before installing the system.
Install the system in compliance with your local and national electrical codes:
– United States: National Fire Protection Association (NFPA) 70; United States National
Electrical Code.
– Canada: Canadian Electrical Code, Part I, CSA C22.1.
– Other countries: If local and national electrical codes are not available, refer to IEC 364, Part 1
through Part 7.
Do not work alone under potentially hazardous conditions.
Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
Do not touch the backplane or midplane with your hand or metal tools.
Remove all jewelry (including rings and chains) or other items that could get caught in the system
or heat up and cause serious burns.
