Might be related to DEFECT000418251. Defect ID: DEFECT000418251     Technical Severity: Medium Summary: On the 20x1G SFP modules, the LED for even numbered ports may not be illuminated even though "show interface" indicates the status of the ports as "UP". Symptom: LEDlinklightsarenotaccuratelyindicatingtheproperstateoftheport. Feature: System - XMR/MLX  Function: Ethernet Optics Reported In Release: NI 05.3.00       Service Request ID: SR 762909
I'm not sure which ver of 5.3 it was resolved in (if any) since I'm looking at 5.4b notes.
