ROUBLESHOOTING
101
Network
If you suspect a network problem, keep in mind the following:
• If the Fiery Server does not appear in the list of printers on the network, another device on the network may have been assigned the same 
Ethernet hardware address. 
• Conflicting network settings may have been configured in Setup and on the customer’s workstation.
• Printing problems may be caused by inappropriate Setup options.
• Application-specific printing errors may be caused by missing or incorrectly placed printer description files.
• System software may be corrupted.
For additional information, see Configuration and Setup, which is part of the user documentation set.
Unable to connect to 
the network, or the green 
LED on the RJ-45 
network port is 
not lit.
Possibly one of the following:
• Network cable is connected to 
the wrong RJ-45 port
• No cable/wrong type of cable is 
connected to the network port
• Network cable or connection
is faulty
• Network is faulty
• If the Fiery Server requires a static IP 
address (for example, in a non-DHCP 
network environment), it may need to 
be reconfigured. A static IP address is 
deleted when system software is 
reinstalled.
• System software is corrupted
• Network interface on the 
Fiery Server motherboard is faulty
1 If the problem persists, have the network administrator 
check Network Setup. To configure a static IP address (if 
applicable for the customer site), work with the network 
administrator as described on 
page 21
.
2 If the problem persists, make sure that the network 
administrator has checked other devices on the network.
If other devices are not functioning, the problem may be 
with the network.
3 If the problem persists, restore the backup, or reinstall the 
system software (see 
page 83
).
Corrupt system software may cause the system to hang.
4 If the rest of the network is functioning properly and the 
problem persists, replace the motherboard (see 
page 53
).
