The maximum number of I/O devices that can be
attached to the 5110, is three.
If a 5103 is
attached, it must be the last I/O device in the
string of I/O devices, because it terminates all
the I/O signal lines. If a 5103 is not attached,
the last I/O device must have a cable terminator
installed. If a 5106 is attached it must be the
first I/O device.
A 5106 can only be attached if the 5110 has an
internal tape drive.
-Disconnect the I/O cable at the 5110 I/O
interface port (see MIM 271).
-Switch the DISPLAY REGISTERS switch to
NORMAL.
-Press RESTART. Wait 25 seconds.
- Perform the failing job, if possible.
