At this point, the client should show a normal boot path.
Recopy the boot program from the server.
1. Transceiver(s) (some transceivers r5 VDC.)
2. Coaxial cable (should be 50 ohm)
3. Twisted pair (pin 13 should p12 VDC to the transceiver)
If the net is not terminated at 50 ohms, the following message may result:
Ethernet cable problem
Requesting internet address for 8:0:20:N:N:N
Swap the media when necessary, and try to reboot the client.
Check the
physical layer
Jammed

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.
Additional ethernet messages indicate that the physical media is damaged or needs to be
revised for proper installation.
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.
This message usually appears after the
client has completed booting.
Sometimes it appears if 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.
Check net termination and run a netstat
to check for traffic and/ or high
incidence of collision.
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 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.
Select the
reported path.
Is the client alive?
Boot the client.
Cable problem
No carrier
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.
