(For wired network) Check to see if there is any LED activity. Brother print servers have two LEDs on the
back panel of the machine. The upper green LED shows Link/Activity (Received/Transmit) status. The
lower orange LED shows Speed status.
No light: If the upper LED is off, then the print server is not connected to the network.
The upper LED is green: The Link/Activity LED will be green if the print server is connected to a
Ethernet network.
The lower LED is orange: The Speed LED will be orange if the print server is connected to a
100BASE-TX Fast Ethernet network.
The lower LED is off: The Speed LED will be off if the print server is connected to a 10BASE-T
Ethernet network.

Print the Network Configuration List and check if the settings such as IP address settings are correct for
your network. The problem may be the result of a mismatched or duplicate IP address. Verify that the IP
address is correctly loaded into the print server, and make sure that no other nodes on the network have
this IP address. For information on how to print the Network Configuration List, see Printing the Network
Configuration List on page 105.
