Service manual

2
This line indicates the type (TYP) of module at each <REFERENCE>(XMI)
node. Scalar processors are type P, and vector processors are type V. The
dashes indicate that the scalar processors are attached to the adjacent
vector processors.
3
This line shows self-test fail status (STF), which are the results of on-
board self-test. Possible values for processors are:
+ (pass)
– (fail)
All processors passed self-test in this example.
4
The BPD line indicates boot processor designation and whether vector
processors are enabled or disabled.
1
When the system completes on-
board self-test, the scalar processor with the lowest XMI ID number
that passes self-test and is eligible is selected as boot processor — in
this example, the processor at node 1.
The results on the BPD line indicate:
• The boot processor (B)
• Scalar processors eligible (E) or ineligible (D) to become the boot
processor
• Vector processors enabled (E) or disabled (D)
In this example the vector processor attached to the scalar processor
at node 4 has been disabled. A vector processor can be disabled by the
SET CPU/NOVECTOR_ENABLED command.
5
During extended test (ETF) all processors run additional tests, which
include reading and writing memory and using the cache. On line ETF,
results are reported for each processor in the same way as on line STF—
a plus sign indicates that extended test passed and a minus sign that
extended test failed.
6
Another BPD line is displayed, because it is possible for a different CPU
to be designated boot processor if the processor first designated as the
boot processor fails the extended testing.
7
The last line of the self-test display shows the ROM and EEPROM
version numbers and the system serial number. Version 2 or greater
ROMs and EEPROMs are required to support vector processors.
1
If a revision J scalar processor has an attached vector module, the vector will be
disabled, and this error message is displayed: ?7D Vector module is disabled–check
<REFERENCE>(XRP) revision at node n. The attached scalar module (T2015) must be
at a minimum revision of K. In addition, the ROMs on any other <REFERENCE>(XRP)
modules must be at a minimum revision of V2.0.
