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 107 and Table 17 on page 107 for the pinout of the console port.
See Figure 35 on page 107 and Table 18 on page 108 for the pinout of the auxiliary port.
See Table 19 on page 108 for the pinout of the Ethernet port.
