Console Port

The console port is an RJ-45 receptacle. Data terminal ready (DTR) and data set ready (DSR) handshake signals are supported. The Request To Send (RTS) signal tracks the state of the Clear To Send (CTS) signal. Table A-2 lists the console port pinouts.

Auxiliary Port

The Auxiliary port is an RJ-45 receptacle that supports remote console interfaces. Table A-3 lists the auxiliary port pinouts.

Gigabit Ethernet Ports

Table A-4 provides cabling specifications for the Gigabit Interface Converters (GBICs) that you install into the Gigabit Ethernet port modules. Note that all GBIC ports have SC-type connectors, and the minimum cable distance for all GBICs listed is 6.5 feet (2 meters).
