Procedure #2: Check the Computer Status Codes

The section below assumes your computer is not running the self test. For information on the status
codes you can see when running the self test, refer to "Procedure #5: Self Test." For more information on
the status codes mentioned below, refer to Chapter 8.
Look at the front panel Status Display. As the computer boots itself, a series of status codes appears on
the display in rapid succession. None of the codes should remain on the display longer than a second or
two. Check for the following codes:
A.
If the LED is displaying a 0, everything is normal. No problem was found in this procedure. Return
to the current procedure or continue with the next procedure on your checklist.
B.
If Status Code 4 remains on the display panel, this indicates that the computer ran out of QUEUE
blocks. Additional QUEUE blocks can be allocated in the system initialization command file.
C.
If Status Code 10, 11, or 12 remain on the display panel, this indicates that during the boot process,
the computer was unable to find AM318.IDV in [1,6], or the terminal driver in [1,6], or the system
initialization command file in [1,4].
D.
If one of the Status Codes 20, 21, 22, or 2E remains on the display panel, the computer did not boot
because of a problem with the boot PROM. Perform "Procedure #6: Alternate Boot." If the
computer does not come up correctly, something serious may be wrong. Call your VAR for help.
Stop.
E.
If Status Code 25 or 35 remains on the display panel, this indicates that the computer was unable to
locate the User File Directory (UFD) in account [1,2] on the boot device. This could indicate a
problem with the format on your boot device, contact your VAR for assistance.
F.
If Status Code 23, 2F, 33, or 3F remains on the display panel, you might have a problem with your
boot device selection. Verify that the primary and alternate boot devices and corresponding unit
numbers in the CMOS Menu are set correctly according to the instructions in Chapter 2. Perform
"Procedure #3: Powerup/Reset." If the computer does not boot normally at this point, call your
VAR. Stop.
G.
If Status Code 24 through 28 or 34 through 39 remains on the display panel, your System Disk
might be the source of the problem. Perform "Procedure #6: Alternate Boot." If the computer boots
correctly, then you can suspect something is wrong with the System Disk. Your VAR can help you
restore your System Disk. If the computer does not boot, something more serious may be wrong. In
either case, call your VAR for help. Stop.
H.
If you see Status Code 29 on the display panel, the computer is trying to warm boot from a tape
device and is searching for a label on the tape. If this status code remains on the display panel for
more than a minute or so, verify the correct tape is mounted in the drive. If you have a known good
warm boot tape in the drive, and the computer will not boot from it, contact your VAR for help.
Stop.
I.
If Status Code 2A, 2b, 3A, or 3b remains on the display panel, your computer is having a problem
loading or executing the system monitor program. Perform "Procedure #6: Alternate Boot." If the
computer boots correctly, you might have a problem with the files on your System Disk. Your VAR
can help you restore these files. If the computer does not boot from the alternate device either,
something more serious may be wrong. Again, contact your VAR for help. Stop.
