display panel. The code comes in two parts, the test number and the
failure code. The characters |- -| delimit the code. The exact syntax is :
|- <test number> - <failure code>-|
The error code is repeated several times before an F (for failure) is
displayed on the panel. A common cause of diagnostics failure is to boot up
the system without any disks in the drive. Your supplier will be able to
advise in case of diagnostic failure.
Stage 2: The manager code is loaded. After hardware diagnostics are
completed, the UM will display b (for booting). This lasts a few seconds
and then changes to L. The manager code is now being loaded. While this
is taking place the other boards will only display a flashing dot.
Stage 3: The rest of the system is booted up. Once the manager is loaded
up, the UM displays I (initialisation). The other slots in the bay are polled
in turn to determine the topology of the bay. Each XIM indicates P to show
that it has been polled. The UM then loads the XIMs. UPM3-based XIMs
are loaded first, followed by UPM1- and UPM2-based XIMs in parallel,
and then by application cards. The cards will display L (for loading).
Stage 4: Ready to go. The LEDs on the cards will successively display o for
operational and very soon afterwards, I for initialisation, and r for
running. The UM display shows the same transition but with a slight
delay after the other boards. The system is operational when the UM
displays r.
2.1.3 If Boot-up Fails
If you can log on to the system, then the Node Manager is operational and
it is possible to establish the reason for failure of any of the other boards by
examining the Alarms screen. If you can't log on, then the boot-up could
have failed for any of the following reasons :–
–
–
–
–
No disks in the drives.
The disks are write-protected or incorrectly formatted.
The disks are in the wrong drives.
The disks contain no load files.
The UM failed its hardware diagnostics (indicated by an F on the
board's display ). It will be necessary to contact your supplier
for advice in this case.
