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 pr int out a
configuration page in the Network STATISTICS inf ormation 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) s tatus.
■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 serv er 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 rec eiving 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 i s 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.
