Preparing to Install the FlexWAN or Enhanced FlexWAN
Module
Note
Before you can install the FlexWAN or Enhanced FlexWAN modules, you must install at least one
supervisor engine in the chassis. Throughout this publication, the term
supervisor engine
refers to
Supervisor 720 Engine.
The following tools adn equipment are required to install the FlexWAN and Enhanced FlexWAN
modules:
•
3/16-inch flat-blade screwdriver for the captive installation screws on the FlexWAN and Enhanced
FlexWAN modules.
•
Antistatic mat or antistatic foam.
•
Your own electrostatic discharge (ESD)-prevention equipment or the disposable grounding wrist
strap included with all upgrade kits, field-replaceable units (FRUs), and spares.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. Port adapters and processor
modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic
interference (EMI) shielding and connectors are integral components of the carrier. Although the
metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.
