I've got a couple 1400 Procurves that I need to clear the configuration on. I can't find any documentation on how to do this.
I found a document for the 1800 series that said to loop a cable from port 1 to port 2 for about 40 seconds to restore the default configuration. I tried that method but it didn't seem to do much. Anybody know how to do this or where I can find the procedure documentation?
Those are unmanaged switches.
They have no configuration you could change and thus no way to reset them.
The HP Procurve 1400-24G (or V1400-24G) is an unmanaged switch, so simply removing the power and turning it back on will reset any counters and timers.
See the 1400-24G manual for more information. (PDF)
