Cabling and Configuring the
25 Mbps Port Adaptor Modules
This chapter describes cabling and configuration procedures for the LightStream 1010
ATM switch 12-port, 25-Mbps PAMs. When your switch leaves the factory, it is configured
as specified in your order and is ready for installation and startup. As your communication
requirements change, you might want to upgrade your system, add components, or change
the initial configuration.
Software and upgrades require specific document part numbers and other frequently
updated information; therefore, only basic software configuration guidelines are included
in this publication. Detailed, up-to-date instructions are included in the LightStream 1010
ATM Switch Software Configuration Guide and command-line interface (CLI) command
descriptions are provided in the LightStream 1010 ATM Switch Command Reference.
This chapter contains the following information:
• Overview of the 25-Mbps Port Adapter Module
• Connecting the Interface Cables and Checking the LEDs
• Configuring the Interfaces
Overview of the 25-Mbps Port Adapter Module
The 25-Mbps Port Adapter Module has twelve 25.6 Mbps ATM ports. Each port is
compliant with the ATM Forum PHY standard for 25.6 Mbps over twisted pair cable and
is ideal for workgroup links (see Figure 9-1). Any of the twelve ports on the PAM can be
configured as redundant links using the switch's routing protocols. The PAM has a 96-pin
Molex connector and a multi-leg 12 RJ-45 cable assembly.
