Hardware & LAN Problems
Problem No. 1
All the Print Server's LEDs are off.
Solution No. 1
Check the power supply or power connection.
Problem No. 2
Print Server's status light continuously stays lit.
Solution No. 2
Reset Print Server by unplugging the power supply and plugging
it back in.
Problem No. 3
Print Server's status light and power light stay on continuously
and do not turn off.
Solution No. 3
Reset the Print Server by unplugging the power supply or by
pushing the reset push button, if fitted.
Problem No. 4
The Print Server unit can not be found on the LAN, so
configuration is not possible.
Solution No. 4
If using 10/100BaseT:
■
Check the Hub. The link LED for the port to which the Print
Server is connected should be ON. If it is Off, there is a
problem in the network cable.
■
On the Print Server , check the LED(s) next to the connector.
If the LED is not ON (or neither LED is On, if there are 2),
the network connection is not working.Check the Ethernet
cable and connectors. If they seem OK, set the DIP Switches
of the Print Server to match your LAN environment.
If using TCP/IP:
■
Ensure that there are no routers between the Print Server and
the computer used for configuration.
■
Ensure that the computer used for configuration has the
TCP/IP network protocol installed. Test its network
connection by seeing if you can locate other LAN devices
from the computer. (e.g. Use Network Neighborhood and try
to browser the network.)
Problem No. 5
I am using DHCP, and getting an IP Address conflict involving
the Print Server .
Solution No. 5
If the Print Server is left on, but the DHCP server is turned off,
then the Print Server will retain its IP Address without the
DHCP Server being aware of it. Simply reset the Print Server so
it will obtain a new IP Address.This problem would also arise if
you assigned static IP Address, which is within the range used
by the DHCP server. If so, use another address which is NOT
within the range used by the DHCP server.
