Additional Ethernet messages indicate that the physical media is damaged or needs to be

revised for proper installation.
Check the setting of the Link
Integrity Test at the DSBE/S SBus
card and the network hub. The
setting must be the same for both.
For Sun equipment, the test is
enabled by default. See
Section 3.9, "Enabling and
Disabling the Link Integrity Test."
The carrier is not complete (usually
the cable path to the transceiver).
Check to see if the twisted pair
cable is fastened correctly.
Go to the server and run ping on the
client after booting the client.
Is the client alive?
Yes
Boot the client.

No carrier
Select the
reported path.
This indicates that the coaxial
or twisted pair is not
connected during boot.
Reconnect the cable and swap
out the transceiver if it is bad.
If the physical layer checks out, check the server to see if the rapd (daemon)
was started. If not, reboot the server and see if it is initialized. Also check the
No
nd and nfsd init. If these daemons are not initialized, reinstall the client. This
path can not assume that the user will have enough UNIX background to fix
the OS. The reinstallation serves as an alternative resolution only.

This message usually appears
after the client has completed
booting. Sometimes it appears if
Jammed
the 50 ohm terminator is removed
on a live net. It can also indicate
that packets are jamming the net
due to excessive net traffic.
Cable problem
Check net termination and run a
netstat to check for traffic and/ or
high incidence of collision.
