Ports and Connectors
The GSS supports the following port connectors on the rear of the chassis:
• Console Port
• Ethernet Connectors
Warning
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits
to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits,
and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45
connectors. Use caution when connecting cables.
Console Port
The GSS has one standard RS-232 serial port located on the rear panel that
operates as the console port. The integrated serial port uses a 9-pin male D-shell
connector. Figure 1-4 shows the pin number assignments for the 9-pin port.
Refer to Table 1-3 for the console port connector pinouts.
