The system does not respond to the password
being entered or the system login prompt is dis-
played when booting in service mode. Verify that the password is being entered from
the ASCII terminal or keyboard defined as the
system console. If so, then the keyboard or its
controller may be faulty.
1. If entering the password from the keyboard
which is attached to the system, replace the
keyboard. If replacing the keyboard does not
fix the problem, replace the I/O board. (See
notes on 2-1.)
2. If entering the password from a keyboard
which is attached to a ASCII terminal,
suspect the ASCII terminal. Use the
Problem Determination Procedures for the
terminal. Replace the I/O board if these pro-
cedures do not reveal a problem.
