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.
