corresponding target device activity, there may be a problem with the SCSI bus configuration. Verify

the SCSI bus configuration.

• Ethernet (10/100)—The LNK should stay permanently lit to indicate an Ethernet link. The ACT indicator

should flash to indicate activity. If either of these indicators fail to flicker, or stay continuously lit, there

may be a problem with the network connection or configuration. Verify the network connection and

configuration. The port must be connected to a Ethernet network to function properly.

Serial port problems

If you experience trouble communicating with the serial port, verify the configuration of the host terminal or

terminal emulation program. The network storage router requires the baud rate to be set correctly: 8 data

bits, 1 stop bit, and no parity. Flow control should be set to none or XON/XOFF, and may cause problems

if set to hardware. Some terminal programs may not support baud rates higher than 19200, so a lower

baud rate may be required. If problems persist, you may want to check the cabling or try a different host.

Be sure the Scroll Lock key on the keyboard of the host computer is not enabled. If a valid Ethernet IP

address is configured, serial configuration settings can also be set via telnet.

In a switched fabric environment, if a login problem is experienced, or if the drives can not be seen,

confirm that the port settings of the network storage router are set for auto-sense or for N-port. Using a

hard ALPA setting with the N-port setting is not a valid configuration.

Windows driver

There are no actual device drivers required for the network storage router. When Windows prompts for a

device driver, this situation occurs because the Active Fabric LUN of the network storage router is enabled.

Solutions to this request for a driver include the following options:

• Disable Active Fabric (or the target LUN for the network storage router, in order to eliminate further

Windows driver requests. You can also accept the Windows prompts and disable the device in the

device manager.

• Optionally, an HP device driver installation file (called an INF file) is included on the User

Documentation CD. The network storage router does not really need an actual driver, as the HBA in the

host PC manages this. However, the included INF file does allow the Windows Device Manager to

Device Manager will no longer consider this network storage router LUN to be an unknown or “newly
