- Green: No alarms
- Yellow: A yellow alarm is occurring on the channel
- Red: A red alarm is occurring on the channel
T1/E1 Line State LEDs
The physical line state of the ports on the T1/E1 interface is indicated by the Line State LEDs. When the ports are up and available, the line state indicator is green. Any other line state changes the port LED to red.
The CPU LEDs provide an indication of the operation of the CPU card. After system power-on, the CPU LEDs should all be green. Any LED changes indicate a CPU error condition.
Serial Interface LEDs
The PCI slot LEDs provide an indication of the activity on the serial card through four LED lights. When activity appears on a card, the corresponding LED lights green.
Ethernet Port LEDs
The Ethernet port LEDs indicate the activity on the Ethernet port. Green indicates the port is active.
