LEDs

OK or Status LED, one tricolor:

• Off—PIC is offline and it is safe to remove it from the router.
• Green—PIC is operating normally.
• Yellow—PIC is initializing.
• Red—PIC has an error or failure.

APP LED, one bicolor:

• Off—Monitoring application is not running.
• Green—Monitoring application is running under acceptable load.

Port LEDs, one per port:

• Off—Port is not enabled.
• Green—Port is online with no alarms or failures.
