Terminal Server Ports
The four Terminal Server port RS-232 interfaces located on the front panel are used to
remotely connect to RS-232 managed devices.
CAUTION
The 8-pin modular Terminal Server Port 1-4 jacks should never be
connected to a telecommunications network and are intended for
connection to RS-232 data interfaces only.
The Terminal Server ports are accessed by establishing a Telnet session to the MX410/MX412
with the TCP Port Number of the particular port. The pin assignments for each of the RS-232
interfaces are listed in Table 4-5.
