Understanding The Leds - Nortel Contivity Extranet Switch 2500 Getting Started

Getting Started with the Contivity Extranet Switch 2500

Understanding the LEDs

The Power LED is green when the power is on; if it is flashing, there is a
hardware failure and you should contact Nortel Networks.
The Hard Disk LED is green, and when it flashes the Switch is either reading or
writing to the disk.
The LAN Port LED is green, and when it flashes the Switch is either transmitting
or receiving data.
Start the Switch and confirm that the interfaces are cabled properly by examining
the two LEDs located adjacent to the RJ-45 connector of the LAN port, or the
LEDs located on the card panel.
Figure 2-4 shows the private LAN Port LEDs. Look at the condition of the LEDs,
then examine the corresponding LED table to better understand the indications.
There are no LEDs for the Dual V.25 WAN interface.
