Useful Troubleshooting Tools

Several tools are available to troubleshoot the 

622Vu

 Advisor operation with the

622Vu

 undercradle.  Each of these tools is described below.

Ping

You can use the Ping function to test if the Advisor can reach the 

622Vu

undercradle.

1.

 

At the MS DOS prompt, type:

ping 15.21.191.201

and press Enter.

This is the default IP address of the 

622Vu

 undercradle.

You should see a timing information about the Ping test if it is successful.

2.

 

If you get messages that the Ping test failed, try the following steps:

Request
timed out

If the request times out, you can conclude that the NIC card is installed
properly.  You can now question the operation of the undercradle and the
supplied crossover cable.  To verify the cable’s operation:

Power On LED should be on.
Sys OK LED should be flashing.
Use the Console application as described in the "Undercradle Not Detected"

procedure in the "Troubleshooting Problems" section of this chapter.

Destination
Host
Unreachable

This message makes you question the installation and configuration of the NIC
card.  The message tells you that the Advisor did not "know" which NIC card
to use to reach the Ping destination.

The Registry Configuration tool can show you the currently set IP Address and
Subnet Mask of the installed NIC card.

                                Undercradle address

            Agilent Advisor     in Config file

IP Address   15.21.191.200       15.21.191.201

Subnet Mask  255.0.0.0

If these values look proper:

Uninstall all PCMCIA/PC CardBus card drivers.
Reinstall the provided Xircom CardBus Ethernet NIC card.
Use the procedures in the earlier installation and configuration topics to

verify the TCP/IP stack is

 

installed and verify

 

IP addresses of the

undercradle and the Advisor.

Repeat the Ping test.
