v Intel PRO 1000 XT Server Adapter

v Alacritech Quad-Port Ethernet Adapter

v IBM ServeRAID-4Lx and 4H SCSI Controller

v Integrated System Management Processor (ISMP)

v Remote Supervisor Adapter (RSA)

v IBM Fast/Wide Ultra SCSI Adapter

v IBM PCI Ultra 160 SCSI Adapter

Integrated Ethernet adapter

This section provides troubleshooting information for problems that might occur with

the 10/100 Mbps integrated Ethernet adapter.

Network connection problems

If the Ethernet adapter cannot connect to the network, check the following:

v Make sure that the cable is installed correctly.

The network cable must be securely attached at all connections. If the cable is

attached but the problem persists, try a different cable.

If you set the Ethernet adapter to operate at 100 Mbps, you must use Category 5

cabling.

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 Determine if the hub supports auto-negotiation. If not, try configuring the

integrated Ethernet adapter manually to match the speed and duplex mode of the

hub.

v Check the Ethernet adapter lights on the operator information panel.

These lights indicate whether a problem exists with the connector, cable, or hub.

– The Ethernet Link Status light is On when the Ethernet adapter receives a

LINK pulse from the hub. If the light is Off, there might be a bad connector or

cable, or a problem with the hub.

– The Ethernet Transmit/Receive Activity light is On when the Ethernet adapter

sends or receives data over the Ethernet Network. If the Ethernet

Transmit/Receive Activity light 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 the NAS

200 engine.

v Check for operating system-specific causes for the problem.

v Make sure that the device drivers on the client and the NAS 200 engine are

using the same protocol.

v Test the Ethernet adapter by running the diagnostic program.
