Troubleshooting the Sensor

This section lists some common installation problems, the possible causes, and the corresponding
solutions.

Problem

Possible Cause

Solution

LED is off.

The control cable has been

disconnected.

Check the control cable and ensure it is

properly connected to both the Sensor and

the bypass switch.

LED is off.

The Sensor is powered off.

Restore Sensor power.

LED is off.

The Sensor port cable is

disconnected.

Check the Sensor cable connections.

Sensor is operational

but is not monitoring

traffic.

Network device cables have

been disconnected.

Check the cables and make sure they are

properly connected to both the network

devices and the bypass switch.

Sensor is operational

but is not monitoring

traffic.

The Sensor ports have not

been enabled in the

Manager.

The Sensor will not monitor traffic on the

ports unless the ports are enabled in the

Manager. Ports are disabled in case of Sensor

failure; you must re-enable them for Sensor

monitoring to resume.

Network or link

problems.

Improper cabling or port

configuration.

Make sure that the transmitting and receiving

cables are properly connected to the Bypass

Switch.

Runts or giants errors

on switch and routers.

Improper cabling or port

configuration.

Make sure that the transmitting and receiving

cables are properly connected to the bypass

switch.

The system fault "Switch

absent" appears in the

Manager Status page.

The control cable has been

disconnected.

Check the control cable and make sure it is

properly connected to both the Sensor and

the bypass switch.
