LED Indicators
The Metrobility “twister” provides three LEDs on the front panel for the visible
verification of unit status and proper functionality. The LEDs also aid in trouble-
shooting and overall network diagnosis and management.
When lit, the LEDs indicate the following status:
• PWR (power): The unit is powered ON.
• LINK (Port 1): Port 1 is receiving idle link signals (if Port 1 is a copper port)
or the input light level is satisfactory (if Port 1 is a fiber port).
• LINK (Port 2): The input light level is satisfactory on Port 2.
