CHAPTER 4

USING THE LANVIEW LEDS

This chapter describes how to use the LANVIEW Diagnostic LEDs to

monitor EMC38-12 status and diagnose problems.

Figure 4-1. LANVIEW LEDS

4.1 PWR (Power)

• On (Green) - Indicates that the EMC38-12 is receiving power.

• Off - Indicates that the unit is not receiving power. Check the input

power source (circuit breakers, fuse, power cord, etc.). If the proper

source is present, the problem could be with the unit.

4.2 XMT (Transmit)

• On (Flashing Green) - Indicates that the unit is transmitting data

packets from the twisted pair port to the ﬁber optic port. The ﬂash of

the LED is pulse stretched for viewing effect. The LED could be on

solid because of this viewing effect.

• Off - No activity.
