Using an MDI-to-MDI Crossover Cable
The 10BASE-T port is configured as an MDI or host port. To connect the
Management Module to an MDI crossover (MDI-X) or switch port, use a
standard RJ-45 jumper cable. To connect the Management Module
directly to a host or another MDI port, use a crossover cable.
Table 7 lists the MDI-to-MDI crossover cable pinouts.
Connecting to an
RS-232 Console Port
Connect the Management Module to a terminal or modem using the
RS-232 Console Port or RS-232 Auxiliary Port connectors. 9-pin
connectors are used for the RS-232 ports.
Table 8 and Table 9 list the console port and auxiliary port pinouts.
