NETWORK INTERFACE UNIT TEST UTILITY
An off-line NNIU01 network interface unit test allows restart-
ing the network interface unit and testing loop communica-
tions. This may be required if there is a problem bringing the
console on-line, and a network interface unit or loop problem
is suspected.
NOTES:
1.
Care should be taken when using this utility. It causes a net-
work interface unit restart. If the network interface unit is restarted
while the OIS console is on-line, normal operation is interrupted.
2.
Access the utility from the OISENGR account.
