Chapter 1 Installing the FlexWAN and Enhanced FlexWAN Modules
Installing a FlexWAN or Enhanced FlexWAN Module Port Adapter
Warnings and Cautions
Observe the following warnings and cautions when installing or removing port adapters.
Caution
Do not slide a port adapter all the way into the slot until you have connected all the required cables.
Caution
To prevent jamming the carrier between the upper and the lower edges of the port adapter slot, and to
ensure that the edge connector at the rear of the port adapter mates with the connection at the rear of the
port adapter slot, make certain that the carrier is positioned correctly.
Warning
During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly
touch the backplane with your hand or any metal tool, or you could shock yourself.
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Warning
This equipment must be installed and maintained by service personnel as defined by AS/NZS 3260.
Incorrectly connecting this equipment to a general-purpose outlet could be hazardous. The
telecommunications lines must be disconnected 1) before unplugging the main power connector or
2) while the housing is open, or both.
