Router Ports

The types of ports found on HP routers include one or more of the following:

Ethernet/802.3 LAN Port with either an AUI-only or AUI/BNC interface:

AUI interface: For connecting through a transceiver to twisted-pair cable, thick or thin coaxial cable, or fiber-optic cable. All models have at least one AUI interface.

BNC interface: For direct ThinLAN connection to a network. BNC interfaces are included on some models, and can be used instead of the corresponding AUI interface on the same port.

Token ring/802.5 LAN Port (either 4 or 16 Mbit/s): For connecting to a Trunk Coupling Unit (TCU) through shielded, twisted-pair cable.

Synchronous WAN Port: For HP Point-to-Point, PPP, SMDS, frame relay, V.25 bis, and LAPB (X.25) connections to other routers. WAN ports support RS-232/V.24/V.28, V.35, X.21, and RS-422/RS-449/V.36 interfaces.

FDDI LAN Port: For connecting to an FDDI network, either directly or through an optical bypass switch.

Console Port: Present on every HP router; allows access to the router by a terminal or a terminal emulator on a personal computer. Through this interface, you can configure, monitor, and troubleshoot the router. This RS-232 console interface can be accessed either locally or remotely through a modem. The baud rate is automatically detected. Also, router firmware enhancements can be downloaded to the routers through this port.
