SRP IOA on page 109
The SRP IOA module provides three management ports (console, auxiliary,
10/100Base-T Ethernet). You can connect a console directly to the RS-232 serial
console port or debug auxiliary 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. These ports are called serial ports, RS-232 ports, or console ports.
These ports are considered a data terminal equipment interface (DTE). Direct
connection to a terminal or PC (which also have DTE interfaces) requires a crossover
cable.
See Figure 35 on page 109 and Table 17 on page 109 for the pinout of the console
port.
See Figure 35 on page 109 and Table 18 on page 110 for the pinout of the auxiliary
port.
See Table 19 on page 111 for the pinout of the Ethernet port.
