SF300-24P console and factory reset problem

Question

My company just bought a SF300-24P, got it configured without much issue.  Today I try to get into it and I can't.  Tried via HTTP and console and nothing happens.  Decided to try to reset it using the button on the front.  Using the documentation, I held down the button for over 10 seconds.  Didn't reset to factory defaults, tried again and rebooted it, still nothing.  What I am I doing wrong.
Also nothing comes up on console window and I'm using the setting for Hyper Terminal that the documentation says I should use.

Answer 1

I know It's late but I believe it is importante to make that register.
I just had the same problem and the solution was aroung the cable. When I used a straight serial cable, It worked well. Check the pinout/wiring:
1 --> 1
2 --> 2
3 --> 3
4 --> 4
5 --> 5
6 --> 6
7 --> 7
8 --> 8
9 can be left open
When I was trying to figure the problem out, I found Cisco 300 CLI Reference Guide (ver 1.3.7) wich tells we could use a null-modem or crossover serial cable. But it's not true.
Of course I must consider I was using an USB to serial adapter (my notebook doesn't have serial port). Perhaps it has created the straight cable issue. I don't know if it will occurs when using a native serial port.
Thanks for the Cisco online support wich helps me.
And I believe it will be interesting to Cisco check the cable pinout and add it on the manuals or website. I just can't find information about db9 f-f cable on any Cisco documentation (about 300 series, of course).
I hope it helps some people.
Kind Regards.
