Analyzing Cables

The Cable Analysis option on the Diagnostics tab lets you monitor the conditions of each wire pair in an
Ethernet Category 5 cable connection within an Ethernet network. The analysis measures the cable quality and
compares it against the IEEE 802.3ab specification for compliance.
Notes:
• You must have administrator privileges to run the cable analysis test.
• The network connection is temporarily lost during an analysis.
• For Broadcom NetXtreme adapters, the cable analysis test can only run for gigabit link speed
connections and when there is no connection.
• This option is not available for all Broadcom network adapters.
To run a cable analysis
1. Connect the cable to a port on a switch where the port is set to Auto and the Speed & Duplex driver settings
are also set to Auto.
2. Click the name of the adapter to test in the Explorer View pane.
3. From the Select a test to run list, select Cable Analysis. If the Cable Analysis option is not available, then
from the Context View tab on the right side of the window, select Diagnostics and then select Cable
Analysis.
4. Click Run.
5. In the error message window that warns of the network connection being temporarily interrupted, click Yes.

Status.
• Good. Good cable/PCB signal paths, but no gigabit link.
• Crossed. Pin short or crosstalk along two or more cable/PCB signal paths.
• Open. One or both pins are open for a twisted pair.
• Short. Two pins from the same twisted pair are shorted together.
• Noise. Persistent noise present (most likely caused by Forced 10/100).
• GB Link. Gigabit link is up and running.
