I cannot console in my Catalyst 3560X 48 POE ports switch. I tried the USB 5-pin and the cat5e cable and nothing worked. I installed the USB driver downloaded from the Cisco website. Any help will be greatly appreciated. Thx

What do you mean with "cat5e" cable? For the built-in serial port, you need to use the rollover-cable usually supplied with the switch (in most cases nowadays it's a 9pin Sub-D with RJ45 cable, mostly blue, but sometimes yellow). As for the USB, are you sure you used the right COM-Port after it's connected? Check your system properties (Windows, or dmsg on Linux) to find the right com port ...

 I am aware of the standard roll-over console cable and I have been using that all my life. But the USB and the straight cat5e is something that Cisco has on the X-series. The USB console is ion the front and the 10/100 fastEthernet console is in the back. None of them works for me. Not sure if I am missing something.

Assuming you use Windows on the computer you try to use as console, does it correctly identify the Cisco serial USB device and load the driver when you plug it in? Also assuming you installed the correct version of the driver (Win7 w/ 32 or 64 bit has different binaries in the download archive IIRC)
As for a 10/100 management device, of course that will not use the rollover cable. Is this switch new and unconfigured, or have you set up the management IP and network? I don't think it has a DHCP server active, so you may need to configure the IP of your PC manually to connect via telnet ...

Yes I was able to connect to the switch by setting a static IP address in the same subnet as the management interface. I'd like to be able to access the swithc using usb or the fastE console port. The driver is good and I can see it from Device manager of my Win 7 64bits. Do I need to configure anything in the console port?

how did you configure the management port? can you post an excerpt fronm the config?
The console port - if the driver shows up in the win7 system overview, you should see the com port assigned to it - what happens if you use e.g. putty to connect to  that port?

See attached to see how I setup my management IP address. I think I may have a driver issue with my Win 7 x64. I tried it on my Win XP Pro and it did not work either. The LED for the USB is not on on the switch.
I am not sure how to make the FastE console work. I assigned an IP address to the interface but the sh int fa0 shows that it is down down.

sh run
interface FastEthernet0
 ip address
 no ip route-cache cef
 no ip route-cache
 no ip mroute-cache
interface GigabitEthernet0/1
 switchport access vlan 200

Switch(config-if)#do sh int fa0

  Encapsulation ARPA, loopback not set

ah, of course... you mentioned earlier you used a straight cat5e to connect your PC to the management Interface ... if it's a FastEth, so no AutoMDX, and if it's not a switch port, but a pure management port, you may need a crossover cable to directly hook up the PC ...
Not sure what is causing your USB problem though... I know on other newer switches that have both USB and serial, during boot you need to be connected to the usb port early, otherwise the initial output will only go to serial  but that's only during boot...

Ok. The usb cable was bad. For the LAN cable, I needed to configured an IP address for the fa0 console interface. Everything is now working.

Well, I guess at least partial points would be nice, as the analysis support and steps helped in isolating the cause and solution ...
