DIAGNOSE: I m t i a t e / R e s p o n d
to Messages
If Other workstations are a Iso af-
fected, the source ofthe problem is
the cabling or file server This utility
will check the networic cabling.
1. To determine whether the problem
is the cabling or the file server, run
the diagnostic program using
remote loopback between two
nodes. If the remote loopback test
passes without errors, the problem
is probably the file server, not the
cabling. If the test fails the prob-
lem is probably the cabling.
2. Check the cable connection to
other computers. In an Ethemet
network using thin cable, check
the computers that are daisy
chained to the computer you are
troubleshooting. In an Ethemet
network using thick cable, check
the drop cable connection at the
transceiver
3, If you think you have a cabling
problem, try splitting segments to
isolate the cable defect, or replace
the cable with one known to be
good, . i
4, Verify that the network cable is
securely attached to either the
BNC, AUI, or UTP port,
5, If the BNC or AUI port is used,
verify that 50 ohm cable ter-
minators are installed as required.
Terminators must be 50 ohm im-
pedance (within 2%) or en;ors may
occur Temninators are installed at
both ends of every cable segment.
6, Make sure that the interconnect-
ing cables meet IEEE standard
requirements.
