Just configured my first set of POE switches. Funny how hard it was to find a working COM port, I wish HP would just enable some sort of USB connection to configure their switches. Ah well, I hooked up a ProCurve 2600-24-PWR to an old system I had, connected the RJ-45 to Serial adapter to the system, fired up Putty-Portable, and got connected via SERIAL connection. Once you assign an IP address to the device you can connect to it via Telnet, again through Putty-Portable.
Obviously I am not going to get into the setup of the device but I wanted to point out one crucial command that must be entered. Its called “Power Pre-Std-Detect”. This allows the detection of pre-standard PoE devices, then provides power to them; see list of supported devices in the product FAQ at www.procurve.com If this isnt enabled, its a good chance that your PoE devices will start to reboot spontaneously. Note that after updating the firmware on a 8-Port PoE switch the “power pre-std-detect” was enabled by default.
If this helps just one person then my job is done
