Administration: Diagnostics

Displaying Optical Module Status

• Status—Wire pair status. Red indicates fault and Green indicates status OK.
• Channel—Cable channel indicating whether the wires are straight or cross-over.
• Polarity—Indicates if automatic polarity detection and correction has been activated for the wire pair.
• Pair Skew—Difference in delay between wire pairs.
NOTE
Displaying Optical Module Status
The Optical Module Status page displays the operating conditions reported by the SFP (Small Form-factor
Pluggable) transceiver. Some information might not be available for SFPs that do not support the digital
diagnostic monitoring standard SFF-8472.
