Follow these guidelines when working on equipment powered by electricity:
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. 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 an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.
 |
Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohm (Mohm). |
Power supply kits include the following:
To remove or install the power supplies, you will also need the following tools and equipment (which are not included):
This section describes how to remove the chassis cover from the router. To gain access to the power supply, you must open the router chassis.
|
Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. |
|
Warning Before working on a system that has an on/off switch, turn off the power and unplug the power cord. |
|
Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. |
