Status Indicators
The TLink option module has four light-emitting diode (LEDs) used to signal
the following events:
DS1
:
• Red continuous when the fiber-optic cable is disconnected (receiver
side).
• Green continuous when fiber-optic cable is connected (receiver side).
• Green blinking when packets are incoming (transmission is on).
DS2
:
• Green continuous: TLink module role is Leader. Transmitting is enabled.
• Green blinking: Transmission (packets are being transmitted, TLink role:
leader).
• Off: The TLink is not configured as a leader
DS3
:
• On (green): External power supply connected
• Off: external power supply not connected
DS4
