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.
