Connecting to a VT-Series Terminal
Follow these steps to connect a VT 320/420-series terminal to a Catalyst 1800 Token Ring switch
(see Figure 1):
Step 1 Plug either end of the EIA/TIA-232 cable into the RJ-45-to-DB-9 female adapter labelled
“Console port.”
Step 2 Connect the console port female adapter to the male DB-9 console port on the front of the
Catalyst 1800 chassis.
Step 3 Plug the RJ-45 connector at the other end of the EIA/TIA-232 cable into the
RJ-45-to-DB-25 female adapter labelled “VT series.”
Step 4 Connect the VT-series DB-25 female adapter to the DB-25 male adapter on the cable
extending from the VT terminal’s COMM port.
Step 5 Turn on the terminal and access the setup directory. Set the following parameters on your
terminal:
After these parameters are set, you can access out-of-band management. Refer to the Catalyst 1800
Token Ring Switch User Guide for instructions on using the console interface.
