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.
