What typical cables can I use for a connection to the router console port?
HP Routers, with the exception of the HP Router 650 and HP Router 210, have a 25-pin female connector as the console port. The HP Router 650 and the HP Router 210 have 9-pin male connectors as console ports. You need to use a RS-232 “Null Modem” cable to connect to the console port of HP routers except the HP Router 650 and HP Router 210. From a terminal or PC with a 9-pin male serial port to all HP routers except the HP Router 650 and HP Router 210 use the HP 24542G (9-pin female to 25-pin male) cable.
