: Obtain another copy of the tape. Repeat this step using the new tape. If
this does not correct the problem, continue with the next step of this
procedure.
6.
Look at the 4 rightmost characters of the Data display for word 1. These 4
characters are the unit reference code.
7.
If the amber light on the 3570 indicator panel is on continuously, see the
“Start” section of the 3570 service information.
8.
See SRC Address Formats to determine the IOP, IOA, and device address.
9.
Find the unit reference code in the following table.
10.
See the “Start” section of the 3570 service information.
