Removing And Replacing The Supervisor Engine - Cisco Catalyst 5000 Series Installation And Configuration Note

•
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.
•
Examine your work area carefully for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Warning
lightning activity.
Preventing ESD Damage
ESD damage occurs when electronic modules or components are improperly handled and can result
in complete or intermittent failures. To prevent ESD damage, follow these guidelines:
•
Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
•
When handling modules or coming into contact with any internal components, always use a wrist
strap connected to one of the following:
— Captive installation screws on an installed module or power supply
— ESD wrist strap connector
— Any unpainted surface on the chassis
•
Handle modules by the edges only.
•
Avoid contact between the modules and clothing. The wrist strap protects only the module from
ESD voltages on the body; ESD voltages on clothing can still cause damage.
•
After removing a supervisor engine, place it on an antistatic surface or in a static-shielding bag.
If you plan to return the module to the factory, immediately place it in a static-shielding bag.
Caution
between 1 and 10 megohms (Mohms).

Avoiding Problems When Inserting and Removing Modules
The ejector levers on the supervisor engine align and seat the supervisor engine connectors in the
backplane. (See Figure 3.) If you fail to use the ejector levers to insert the supervisor engine, you can
disrupt the order in which the pins make contact with the backplane. When removing a supervisor
