4.2.2.2 nn1 n - Hardware Revision Level Checksum Error -
Problem
The server's nonvolatile memory is faulty.
Correction: There is no correction for this problem. You can continue
to use the server. However, performance enhancements based upon
hardware revisions are not in effect. This means that the
MUXserver 100 may run slightly slower than it would otherwise.
If
you wish to return the unit to DIGITAL, refer to Section 4.7,
DIGITAL SERVICE.
With this problem, asterisks

appear in the hardware revision field
in the. SHOW SERVER display.
4.2.2.3 n1nn - Ethernet Loopback Error -
The following error message ap-
pears on the console terminal:
Local -910-lmage load not attempted, network
commun;cat;on error
Problem
There is a faulty or loose transceiver cable.
Correction: Check the cable that runs from the MUXserver 100 unit
to the transceiver, DELNI, or Etherjack. Be sure the cable is se-
curely connected at both ends. Check the cable for any signs of
damage.
If
you have an H4080 turnaround connector, you can verify the op-
eration of the transceiver cable. Replace the transceiver with the
H4080 and then initialize the server by entering <CTRL/P>.
If
the
continual green light and the n1nn status persist after the next self-
test, the cable is likely to be at fault.
If
the error message disap-
pears the transceiver or Ethernet tap may be malfunctioning (see
below).
NOTE
When the green light glows steadily with the H4080 replacement,
the server attempts to down-line load the server software. Since the
H4080 is not connected to the network, the down-line load fails.
