Verifying the Installation
You can verify the probe’s installation by looking at the status LEDs on the front
or back of the probe. LEDs on the back of the probe show the status of each port
and the LEDs on the front of the probe indicate the status of the 10Base-T/
100Base-TX telemetry interface. After the probe restarts (boots), it runs a power-
on self-test (POST) and then starts normal operations.
The Fault LED is briefly turned on (about three seconds) during the POST. After
the probe passes the POST, the Fault LED turns off. The Activity LED flashes
during network activity. The ~Line On or Power LED should be on to indicate that
power is applied to the probe.
After the probe has passed its self-tests, look at the status LEDs to verify your
installation. The status LEDs should be in the following states:
LED State
Activity Flashing, if connected to a network with traffic, or may
appear to stay on solid during periods of steady traffic.
~ Line On or Power On solid
Fault Off
You can use NetMetrix to verify that the probe can be reached (refer to your
NetMetrix documentation).
