LEDs

OK/FAIL LED, one bicolor:

• Steady green—DPC is functioning normally.
• Blinking green—DPC is transitioning online or offline.
• Red—DPC has failed.

LINK LED, one green per port:

• Off—No link.
• On steadily—Link is active.

TUNNEL LED, one green per XFP port:

• Off—Normal operating mode.
• On steadily—Port configured in tunnel mode.

The SFP Link LEDs are labeled in groups of five:

• 0/0 for 0/0 through 0/4
• 0/5 for 0/5 through 0/9
• 1/0 for 1/0 through 1/4
• 1/5 for 1/5 through 1/9

The XFP ports are labeled top to bottom 2/0 and 3/0.
