Connecting the Console Terminal and Modem
Use a console terminal for local administrative access to the router. You can
connect only a terminal to the console port. Use the auxiliary port with a
terminal or a modem for remote access to the router.
Connecting to the Console Port
Take the following steps to connect a terminal (an ASCII terminal or a PC
running terminal emulation software) to the console port on the router.
1. Use an RJ-45 roll-over cable and an RJ-45-to-DB-25 or RJ-45-to-DB-9
adapter to connect a console terminal to the console port. The adapters
provided by HP are labeled “Terminal”.
Additional information on roll-over cable pinouts is provided in the
appendix A “Cable Specifications”.
