Asynchronous Transfer Mode (ATM) Module Installation and User Guide 2-9
Making Network Interface Cable Connections
f Use a #1 Phillips-head screwdriver to tighten the captive screw on each end of
the module front panel to prevent the module from being dislodged from the
backplane connectors and to ensure satisfactory protection from EMI.
Repeat this procedure for additional modules, if applicable.
Making Network Interface Cable Connections
Use the appropriate type of optical-fiber cable—single-mode—to connect the ATM ports
of your BlackDiamond 6800 series switch to another switch or router.
Kinks and sharp bends can destroy or impair the cable’s ability to convey light
pulses accurately from one end of the cable to the other. Use care in dressing
the optical-fiber cables: provide satisfactory strain relief to support the cable and
maintain an adequate bend radius at all cable turns, particularly where the cable
connects to the I/O module.
Working carefully, one port at a time, follow these steps:
1 Verify that you have identified the correct optical-fiber cable for the ATM module
port.
2 Use an alcohol wipe or other appropriate cleaning agent to clean the fiber element
on the cable connectors to be sure they are free of dust, oil, and other contaminants.
3 Align the transmit (Tx) and receive (Rx) connectors on the optical-fiber cable with
the correct corresponding connectors on the ATM module.
On the ATM module, the transmit (Tx) connector on each port is the top connector.
4
Press the cable connectors into their mating connectors on the ATM module until the
cable connector is firmly seated.
5 Repeat steps 1 through 4 for the remaining cables on this or other ATM modules.
6 Dress and secure the cable bundle to provide appropriate strain relief and protection
against bends and kinks.
