portRegTest
Figure 4-2 shows the
portRegTest
command, which checks registers and static
memory located on the motherboard. Registers are set under firmware control
and are used to control the hardware route selection and other internal
hardware functions. This test verifies that all registers are accessible.
IMPORTANT:
This test cannot be executed on an operational switch. Before issuing the
portRegTest command, disable the switch using the switchDisable
command.
switch:admin> portRegTest
Running Port Register Test .... passed.

NOTE:
Related error messages are DIAG-REGERR, DIAG-REGERR_UNRST, and
DIAG-BUS_TIMEOUT.
centralMemoryTest
Figure 4-3 shows the
centralMemoryTest
command, which checks the central
memory in each Application Specific Integrated Circuit (ASIC). This test
ensures that:
■
The built-in self-repair (BISR) circuit in each ASIC chip does not report
failure to repair bad cells (bisr test).
■
The data cells can be uniquely written and read correctly
(data write/read test).
■
The data in any one ASIC can be read from any other ASIC
(asic-asic test).
■
Bad parity can be detected and flagged in the error register and an
interrupt can be posted (parity error test).
■
Buffer number error can be detected and flagged in the error register and
an interrupt can be posted (buffer number error test).
■
Chip number error can be detected and flagged in the error register and
an interrupt can be posted (chip number error test).
IMPORTANT:
This test cannot be executed on an operational switch. Before issuing the
centralMemoryTest command, disable the switch using the switchDisable command.
