If you directly connect two workstations (without a hub) or if you are not using a
hub with X ports, use a crossover cable.
Note:
To determine whether a hub has an X port, check the port label. If the
label contains an “X,” the hub has an X port.
v
If you are connecting through an Ethernet hub or repeater, make sure that the
signal LEDs are operational while the device is on and connected to the LAN.
v
Determine whether the hub supports auto-negotiation. If not, configure the
integrated Ethernet controller manually to match the speed and duplex mode of
the hub.
v
Check the Ethernet controller LEDs on the operator information panel.
These LEDs indicate whether a problem exists with the connector, cable, or hub.
– The Ethernet Link Status LED is on when the built-in Ethernet controller
receives a LINK pulse from the hub. If the LED is off, there might be a bad
connector or cable, or a problem with the hub.
– The Ethernet Transmit/Receive Activity LED is on when the built-in Ethernet
controller sends or receives data over the Ethernet network. If the Ethernet
Transmit/Receive Activity LED is off, make sure that the hub and network are
operating and that the correct device drivers are loaded.
v
Make sure that you are using the correct device drivers, supplied with your NAS
Gateway 300.
v
Check for causes for the problem that are specific to the operating system.
v
Make sure that the device drivers on the client and NAS Gateway 300 are using
the same protocol.
v
Test the Ethernet controller by running the NAS Gateway 300 diagnostic
programs, as described in “Diagnostic programs” on page 93.

Ethernet controller problem
Suggested action
Ethernet-link status light is
not on.
v
Ensure that the engine is powered on.
v
Check all connections at the Ethernet controller.
v
Check the cable.
v
If you manually configured the duplex mode, ensure that you also manually
configured the speed.
v
Run Base System Diagnostics on the LEDs.
If the problem remains, go to “Starting the diagnostic programs” on page 94 to run all
of the diagnostic programs.
The Ethernet transmit/receive
activity light is not on.
Note:
The Ethernet Transmit/Receive Activity LED is on only when data is sent to or
by this Ethernet controller.
v
Ensure that you have loaded the network device drivers.
v
The network might be idle. Attempt to send data from this workstation.
v
Run Base System 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.
Data is incorrect or sporadic.
v
Ensure that you are using Category 5 cabling when operating the NAS Gateway
300 at 100 Mbps or 1000 Mbps.
v
Make sure that the cables do not run close to noise-inducing sources, such as
fluorescent lights.
