RE: Cat 6509 auto reload

2001-03-20 Thread hmalmgren

I've seen this with other Cisco switches and Dell laptops.  Basically, the
laptop is sending out weird signals out the serial port during the reboot.
These weird voltages somehow screw up the catalyst, and cause it to reboot.
The only solution I've found is to disconnect the serial cable during laptop
reboots, and don't connect it to the switch until after HyperTerminal is
happily running.

Subject: Cat 6509 auto reload


Hi guys
I encountered a bizarre situation whereby the Cat 6509
is automatically reloaded after I rebooted my IBM
Thinkpad.  The connection is via Thinkpad serial port
to the switch's console.  At that moment, there is no
hyperterm session and the notebook is running NT4
workstation.  Anyone has input on this?

Cheers
Kevin

Its actually a problem with Windows 2000 and the way the Serial port outputs
the signal

SGP... are you seeing it on W2K on that Thinkpad??
