If you cannot make any of the connections in step 2, check the
following:
a
Make sure the printer is powered on and on-line.
b
Check the cabling, network connection, and print out a
configuration page in the Network STATISTICS information to
see if bytes are being transmitted and received.
c
Check to see if there is any LED activity.
Brother print servers have two LEDs on the back panel of the
printer. The upper side LED shows Link/Speed status. The
lower side LED shows Activity (Receive/Transmit) status.
■
No light:
If the both of two LEDs are off, then the print server is not
connected to the network.
■
Link/Speed LED is orange: Fast Ethernet
The Link/Speed LED will be orange if the print server is
connected to a 100BaseTX Fast Ethernet network.
■
Link/Speed LED is green: 10BaseT Ethernet
The Link/Speed LED will blink if the print server is receiving or
transmitting data.

If you are using a repeater or hub, make sure that SQE
(heartbeat) is turned off at the hub (if applicable). Also, if you
have a hub or multi-port repeater, verify that the hub or repeater
port is good by trying the print server on a different port or on the
other hub or multi-port repeater.
5
If you have a bridge or router located between the print server
and host computer, make sure that the device is set up to allow
the print server to send and receive data from the host. For
example, a bridge can be set up to only allow certain types of
Ethernet addresses to pass through (a process known as
filtering); therefore, such a bridge must be configured to allow
Brother print server addresses. Likewise, a router can be set up
to pass only certain protocols, so be sure that the desired
protocol can be passed through to the print server.
