3-8). These display-only selections let you view the following array
information:

The menu gives you access to three firmware parameters: firmware
revision level ( ); the results of a checksum test (
); and a display of the hexadecimal tallies of the checksum test
( ).
FIRMWARE REV

PROM device. Two submenus display the date and time associated with the
firmware revision, and a third submenu displays the model number of the array.
TEST CHECKSUMS
This item and its submenu display, as or , the results of a test in
which expected checksums are compared to actual calculated checksums of the
current contents of the Primary (PR) firmware buffers, and the BIST buffer.
Matching checksums for a buffer verify that the contents of that buffer have
not changed and it passes the test.
DISP CHECKSUMS
This item is similar to the item except that, instead of
showing a or condition, the actual checksums are displayed in
hexadecimal. Two submenu items are associated with . In
the second submenu item, there are four entries: at the upper left, the expected
checksum from the primary buffer appears; at the lower left, the calculated
checksum for the primary buffer is shown; at the upper right, the expected BIST
checksum appears; and at the lower right, the calculated BIST checksum
appears.
TEMP
SENSOR
