Check to make sure the communication path between the XL or EL and the workstation is not hampered. Try viewing the NetportExpress print server information from a workstation with a Novell approved IPX configuration. Check that the cabling segment is within IEEE specification. 10baseT cabling should not exceed 100 meters and thin wire should not exceed 185 meters. Cable that is used to connect a workstation adapter may be longer than the specification.
Many adapters can withstand longer cable lengths.
The NetportExpress print server is much more sensitive to cables that are longer than the specification. If NPAdmin or NetPort Manager doesn't hear back from the device within this time period, NPAdmin reports Not Responding or NetPort Manager show the XL or EL greyed out. This sometimes happens on busy networks when the NetportExpress print server is connected across wide area links. This product is no longer being manufactured by Intel.
