SSG 20 Hardware Installation and Configuration Guide
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.
Mini Physical Interface Module Port Descriptions
Each mini physical interface module (PIM) supported on a device has the following components:
One cable connector port—Accepts a network media connector. Figure 5 shows the available mini PIMs. You can install up to two mini PIMs in a device.
