Suggested Action
Check the following:
v Ensure that the hub is powered on.
v Check all connections at the Ethernet adapter and the hub.
v Check the cable. A crossover cable is required unless the hub has an X
designation.
v Use another port on the hub.
v If the hub does not support auto-negotiation, manually configure the Ethernet
adapter to match the hub.
v If you manually configured the duplex mode, ensure that you also manually
configure the speed.
v Run diagnostics on the LEDs.
If the problem remains, go to "Starting the diagnostic programs" on page 98 to run
the diagnostic programs.
Check the following:
Note: The Ethernet Transmit/Receive Activity LED is On only when data is sent to or
by this Ethernet adapter.
v Ensure that you have loaded the network device drivers.
v The network might be idle. Try sending data from this workstation.
v Run diagnostics on the LEDs.
v The function of this LED can be changed by device driver load parameters. If
necessary, remove any LED parameter settings when you load the device drivers.
Check the following:
v Ensure that you are using Category 5 cabling when operating the NAS 200 engine
at 100 Mbps.
v Make sure that the cables do not run close to noise-inducing sources like
fluorescent lights.
Check the following:
v Ensure that the cable is connected to the Ethernet adapter.
v Ensure that the PCI system BIOS is current.
v Reseat the adapter.
v Ensure that the adapter you are testing is supported by the NAS 200 engine.
Go to "Starting the diagnostic programs" on page 98 to run the diagnostic programs.
Check the following:
v Run diagnostics for the Ethernet adapter.
v Try a different connector on the hub.
