LanProbe Operation

Restarting the Probe

3.Press 7 to execute a warm start and exit LanProbe’s Main Menu. The warm start occurs immediately. The Activity and Fault LEDs are turned on during a warm start. When the warm start completes, the Activity LED flashes to indicate traffic (if present), the Fault LED turns off, and the ~Line On (or Power) LED is on.

Cold Start

A cold start resets all of LanProbe’s measurement data as well as all alarm, event, filter, and user-defined statistics configuration to their default values. Basic communications configuration parameters (IP address, default gateway IP address, and subnet mask) are not reset.

You can cold start LanProbe by doing one of the following:

zPressing the CONFIG Button twice within one second.

Selecting the menu item Cold start and Exit from LanProbe’s Main Menu when you have a local terminal connected to the probe, as described on

zpage 75.

Using Agilent NetMetrix to execute a LanProbe cold start. Refer to your NetMetrix documentation for details.

Table 5-6 on page 72 shows which data and parameters are reset during a cold start or warm start of LanProbe.

Pressing the CONFIG Button Twice

Pressing the CONFIG button twice within one second causes the probe to cold start.
