The SRP I/O module provides two management ports. You can connect a
console directly to the RS-232 serial port using a shielded straight-through
cable with a female DB-9 connector on one end and a male DB-25 with a
crossover adapter on the DB-25 end. This port is called the serial port, the
RS-232 port, or the console serial port. Figure 55 shows the location of the
serial port and the sequence of the pins in the RS-232 connector.
The console port is considered a data terminal equipment interface
(DTE). Direct connection to a terminal or PC (which also have DTE
interfaces) requires a crossover cable.
