1. Power up the system by turning the lower key switch to Halt and the
upper key switch to Enable.
2. Check the self-test display for the two processors, each indicated by a
P on the TYP line in the example. If the processors show a plus sign
(+) on both lines STF and ETF, they passed self-test.
3. Check the self-test display for the new memory modules, indicated by
an M on the TYP line, as shown in the example. All four memories
passed self-test, as indicated by plus signs (+) on the STF line.
In Example 3–1,
1
is showing a module failure at node 4 in the VAXBI
card cage attached by the DWMBB module in slot D of the XMI. The failure
at
2
is showing a failure of the DWMBB attached through node E on the
XMI.
In this particular example, the failure at
1
was caused by a DMB32
module. This module was not properly cabled. If you receive failures within
a VAXBI cage, then run diagnostics for the respective modules, if needed.
If you have a DWMBB failure, check the cabling on the backplane
connecting the DWMBB/A and the DWMBB/B modules.
Check the error messages. The message ?004F appears (see
3
). See the
VAX 6000: Installing Model 500 Processors
manual for instructions on how
to set the system serial number and how to set power to the proper value.
