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.

Basic verification
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.
Login problems
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
register the network storage router’s network storage router LUN as a system device. Thereafter, the
Device Manager will no longer consider this network storage router LUN to be an unknown or “newly
