Capturing output from a console
Some information, such as boot information is only outputted directly to the console. To capture
this information, you must connect directly to the switch through its management interface, either
a serial cable or an RJ-45 connector that is specifically used for Ethernet connection to the
management network.
1. Connect directly to the switch using hyperterminal.
2. Log in to the switch using an account with admin permissions.
3. Set the utility to capture output from the screen.
Some utilities require this step to be performed prior to opening up a session. Check with your
utility vendor for instructions.
4. Enter the command or start the process to capture the required data on the console.

Building a case for your switch support provider
The questions listed in “Basic information” should be printed out and answered in their entirety
and be ready to send to your switch support provider when you contact them. Having this
information immediately available expedites the information-gathering process that is necessary to
begin determining the problem and finding a solution.
