Error Messages 920 And 921; Error Message 922 And 923 - Digital Equipment DECserver 300 Problem Solving

4.3.1 Error Messages 920 and 921
Local -920- Parameter checksum error on port(s) n
Local -921- Factory-set parameters will be applied to port(s) n
Problem
The permanent characteristics for the indicated port do not pass the
internal checksum test. The factory-set defaults will be applied
when the server image is down-line loaded.
Correction: Enter the DEFINE PORT command to reset the
server characteristics to values of your choice. Then reinitialize
the server again using the INITIALIZE command.
Correction: Reset the server characteristics using the software
reset switch (S 1) on the back of the server. First, unplug the server
power cord. Then, press and hold the reset switch in while you
reinsert the server power cord. Continue to hold the reset switch in
for one second after power up.
Resetting Sl causes the factory-set port characteristics to be re-
loaded into the server permanent database. If resetting S 1 fails to
correct the problem, the server memory that stores the server char-
acteristics is faulty. Return the server to Digital Equipment Corpo-
ration for repair or for replacement. See Chapter 8.

placement. See Chapter 8.
