Chapter 14 Router LED Locations and States
LED Locations and State Descriptions
ETH LEDs—Fast Ethernet Interface Status
SFP LEDs—Combo Port and SFP Port Status
The ETH 2/1 and ETH 2/2 interfaces are shared. Each interface (ETH 2/1 and ETH 2/2) supports either
a fiber optic GE connection (using an SFP module) or a copper GE connection, but not both. For more
information, see the “Combo Ports” section on page 3-25.
