SRP I/O Module on page 131
CT1 and CE1 I/O Modules on page 134
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 54 on page 131 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.

Table 18 on page 132 lists the pinout for the serial cable's RS-232 connector.
