SRP I/O Module

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 C-1 shows the location of the serial port and the sequence of the pins in the RS-232 connector.

Table C-2 lists the pinout for the serial cable's RS-232 connector.

Once you have configured an IP address on the system, you can connect a console running Telnet to the 10/100Base-T Ethernet port on the SRP I/O module. The system ships with a straight-through cable having a male RJ-45 Ethernet connector on each end. Figure C-2 shows the location of the Ethernet port and the sequence of the pins in the RJ-45 connector.
