We are about to get our first managed switch at work (Procurve 2520G-24-PoE), and this lowly programmer gets to put on his admin hat and try to configure it. The switch has an RJ45 serial port for console access. My laptop has USB ports but no serial port. In fact, there isn't a single computer in the office with a serial port.

I've seen USB-to-DB9 adapters, but I need to go from USB to RJ45 (serial). How would I go about accomplishing this? Do I need two adapters? Will USB-to-DB9 and then DB9-to-RJ45 work?

Thanks in advance.
