ATM Modules
1-Port OC-12 ATM Module (WS-X6101-OC12-MMF)
The 1-port ATM module (WS-X6101-OC12-MMF) provides one direct 
connection and one standby connection between the ATM network and the switch 
using two multimode, SC, fiber-optic connectors. (See Figure 1-37.)
The CONSOLE PORT allows you to access the switch either locally (with a 
console terminal) or remotely (with a modem). The CONSOLE PORT is an 
EIA/TIA-232 asynchronous, serial connection with hardware flow control and an 
RJ-45 connector. 
The CONSOLE PORT mode switch allows you to attach either a terminal or a 
modem to the CONSOLE PORT. 
Note Use a ballpoint pen tip or other small, pointed object to access the CONSOLE 
PORT MODE switch. 
Use the CONSOLE PORT MODE switch as follows:
• Mode 1—Switch in the in position (factory default). Use this mode to connect 
a terminal to the console port using a console cable and a DTE adapter. You 
can also use this mode to connect a modem to the console port. 
• Mode 2—Switch in the out position. Use this mode to connect a terminal to 
the console port using the Catalyst 5000 family Supervisor Engine III console 
cable (not provided).
