Compared to internal diagnostics, LEDs
provide which of the following
advantages?
1. They simplify diagnostic software
2. They are easier to read than displayed
messages
3. They save random access memory
space
4. They enable the operator to select
tests
9-65.
Under DOS, you can also use disk based
diagnostics with test selection menus.
These menus usually provide which of the
information on the monitor?
1. Test selection only
2. Test status only
3. Test status and error indications only
4. Test selection, test status, and error
indications
9-66.
In addition to providing information on the
operating system and software programs,
panels on some minicomputers provide
which of following controls and indicators?
1. Power only
2. Temperature only
3. Power and temperature

Internal diagnostics, called built-in tests
(BIT’s), are designed to perform tests on
which of the following devices?
1. CPUs only
2. IOCs only
3. CPUs and IOCs only
4. CPUs, IOCs, and any optional circuits
9-68.
The pass/fail results of BITs will be
displayed on the front panel. To decipher
an error code from a failed test result and
find the location of the module that may fix
the problem, you should take which of the
following actions?
1. Ask the senior DS
2. Look at the fault isolation table
3. Write down the error code and submit
it to the trouble- shooting desk
