AUX Port
The auxiliary (AUX) port is an RJ-45 serial port wired as data terminal equipment
(DTE) that can be connected to a modem to allow remote administration. We do not
recommend using this port for regular remote administration. The AUX port is
typically assigned to be the backup serial interface. The baud rate is adjustable from
9600 bps to 115200 bps and requires hardware flow control. Use a straight-through
cable when connecting to a modem and a crossover cable when connecting to
another DTE device.
See “Connectors” on page 60 for the RJ-45 connector pinouts.

Each mini physical interface module (PIM) supported on a device has the following
components:
One cable connector port—Accepts a network media connector. Figure5 shows
the available mini PIMs. You can install up to two mini PIMs in a device.
