Unable to console into a new Cisco switch - Putty or SecureCRT

Hello Cisco Experts,

I have a brand new Cisco switch (I just opened the box about an hour ago).  I plugged my trusty console cable (with a Keyspan usb to serial adapter) into my laptop and into the switch and powered the switch up.  Everything was going as planned and I could see the switch booting up (in SecureCRT and Putty).  However, when the switch got to the stage where it asked me if I wanted to do the initial setup, I typed in “no”, but terminal emulation software didn’t recognize the input.  For whatever reason, my input is not being recognized by either terminal emulation program.  My settings for both are as follows:

Port = Com5 – I know this is right because I can see the switch booting
Baud rate = 9600
Data bits = 8
Parity = None
Stop bits = 1
Flow control = None

I thought my issue may be the driver for my Keyspan adapter, so I checked for the latest driver.  I had the latest driver.

I though the issue may be my console cable, I plugged into a different switch and it worked fine.

Any ideas?

Thanks,
Nick

If Keyspan adapter works with different switch should be working in that switch also, there's no reason not to.
Also if you can see switch boot up it mean that COM port and BAUD are OK.
I guess that you can try with Flow control XON/XOFF but I don't expect to change anything (I set my putty that way).
It could be faulty switch. What model is that?
The only thing that I would try to do (just in case) before I would contact support is find some computer with integrated serial port and try that way (but, again, I don't expect that will solve anything, but I always like to try eliminate whatever I can before contacting support).

Sounds like your Hardware flow control (not XON/XOFF) is configured wrong ... switch it and see what it does ...
Also, you didn't mention what Switch you got, but many of the newer models have a USB console port ... if it does, download the driver from the Cisco website and try to connect via that port ... works pretty reliably for me ...

Thanks for the input, sorry it took so long to get back to this.  I have two new 3650s.  My configuration works on one of the 3650s, but not the other.

Did you try the Mini-USB console port on the switch?

I don't have a mini-usb cord.  I'm going to have to pick one up.

... it's just a standard Mini USB as was and is used for many smart phones, card readers, cameras etc. ... nothing special there ...

It looks like the console port on the switch is bad after talking with TAC.

If it is bad console port and you just bought it, replace it right away.
