Terminal Port Or Terminal Hardware Problems - Digital Equipment MUXserver 100 Reference Manual

The file name of the dump file on the host is:
ASDMPnnnn.SYS
Here 'nnnn' are the last four digits of the server's Ethernet address.
For example, a MUXserver 100 with Ethernet address 08-00-2B-00-
16-AC generates a dump file at
SYS$SYSROOT:[DECSERVER]ASDMPI6AC.SYS on a VAXNMS
dump host.
If error message number 914 appears on the supervisor terminal,
the up-line dump is not suecessful. There may be Ethernet problems
inhibiting transmissions between the server and the up-line dump
host. Refer to Section 4.6, PROBLEMS INVOLVING THE
ETHERNET.
4.2.6 Terminal Port or Terminal Hardware Problems
If
the situations discussed in Sections: 4.2.1 (Server Green Light Off) to 4.2.6
(Message Number 913 Appears) do not apply, the behavior of the terminals is
the primary indicator for troubleshooting.
Problem The terminals exhibit one or more of the following kinds of behavior:
• The terminals have no display, and do not respond to keyboard
entries.
• The terminals have a screen display but are non-responsive.
• Not all the characters appear on the terminal screens.
• Nonsense characters appear on the terminals.
Correction: Attach a loopback connector, H326, in place of the ter-
minal, and use the command
LOCAL> START TEST PORT
n
LOOPBACK
Wait a few minutes, then stop the test and note the result.
LOCAL> STOP TEST PORT
n
