LANVIEW LEDS (CSX1200-E11-MOD)

The LANVIEW LEDs are located on the hub portion of the CSX1200-E11-MOD’s back panel. These LEDs are convenient troubleshooting tools that can help you diagnose power failures, collisions, cable faults, and link problems. There are three categories of LANVIEW LEDs: Receive LEDs, Collision LEDs, and Link LEDs.
