Open Cable — Indicates that a cable is connected on only one side.
–
Short Cable — Indicates that a short has occurred in the cable.
•
Cable Fault Distance — Indicates the distance from the port where the cable error occurred.
•
Last Update — Indicates the last time the port was tested.
•
Approximate Cable Length — Indicates the estimated cable length. This test can only be
performed when the port is up and operating at 1 Gbps.
Performing Optical Tests
The Optical Test Page allows network managers to perform tests on Fiber Optic cables. Optical
transceiver diagnostics can be performed only when the link is present. During the port test, the port
moves to a down state.
The Optical Test Page contains the following fields:
•
Port — Displays the port number on which the cable is tested.
•
Temperature — Displays the temperature (C) at which the cable is operating.
•
Voltage — Displays the voltage at which the cable is operating.
•
Current — Displays the current at which the cable is operating.
•
Output Power — Indicates the rate at which the output power is transmitted.
•
Input Power — Indicates the rate at which the input power is transmitted.
•
Transmitter Fault — Indicates if a fault occurred during transmission.
•
Loss of Signal — Indicates if a signal loss occurred in the cable.
