Verify connectivity with an echo request.
In most network environments, an echo request is accomplished using the
ping
utility. For the exact syntax for the
ping
or other echo request utility,
refer to your network documentation. A normal response to multiple echo
requests is 9, 10, or possibly 11 packets transmitted for every 10 echo
requests.
If there is no response to the echo request, first check the command line. If
an IP address is used in the echo request command line, then the IP address
typed in the command line should match the IP address stored in the
HP 16500B Ethernet Configuration menu. If a hostname was used in the
command line, then check the node names database to see that the IP
address and the hostname for the HP 16500B were correctly entered.
After verifying the command line, check to make sure the hardware is
connected and operating properly. To verify operation of the interface
module, refer to "To verify the interface module performance" in Chapter 3.
An intermittent response to the echo request indicates a problem with the
LAN itself. Use a LAN analyzer or LAN management software to monitor
activity and determine where bottlenecks or other problems are occurring.

Mount the HP 16500B system with an NFS mount.
An NFS mount of the 16500B system depends on the network environment
the system is being mounted to. For UNIX, the
mount
command with the
computer name and mount point are required. In MS-DOS, a virtual drive
specifier and 16500B IP address are required. File Manager in MS-Windows is
used to mount in an MS-Windows environment. In all cases, either the
16500B file server /control or /data directory must be specified depending on
whether the 16500B system is being mounted for control or data.
The normal response to an NFS mount in most cases is the command line
prompt reappears. If the system includes a utility to view the mount table
(for example, in UNIX, the
mount
command alone displays /etc/mnttab),
then the 16500B remote file server should appear in the table of mounted
devices.
If error messages appear, then check the command line syntax. If the syntax
is correct, then resolve the error message directly using your network
documentation. Note that an error message appears if you try to mount too
soon after power-up. You need to wait at least 15 seconds after the System
Configuration menu is displayed on the HP 16500B display before attempting
to mount.
