MRV Communications LX-4000 Series manual Rear Panel LEDs, Port Status LEDs

Installing the LX-4000 Series

Port Status LEDs

Each of the eight (or 16, or 32, or 48) green LEDs flash when receive, transmit, or status activity is detected on its corresponding serial port. The port status LEDs are used in several ways. During the initialization process, the LEDs indicate self-tests are being performed, and if any self-test fails, they indicate an error code. After a POST test and a system software boot, the lights indicate when a port is actively being used.
