Cabling the Switch

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 3-3 shows the LAN Port LEDs. Look at the condition of the LEDs, then examine the corresponding LED tables to better understand the indications.
