Fixing Internal Memory Problems
The H8000FW uses solid-state memory circuits to store programs, the routing
configuration, and setup. These circuits use a long-life battery to keep them alive while
the H8000FW is turned off. Whenever the computer in the H8000FW updates that
memory, it performs an operation called a "checksum" and stores the result. A checksum
is a calculation whose result characterizes what is stored in memory. A second run of the
checksum calculation should result in the same characterization,
if the memory hasn’t changed
.
When the H8000FW is turned on, it runs a checksum calculation on the memory and
compares the result against the stored result. If there is a discrepancy, the H8000FW
reports an error.
In the unlikely event that an "internal memory
checksum error" occurs, there may be a critical
problem with what is stored in memory. The
service function
fix internal
on the
service
menu page in the
SETUP
area will remove the checksum error by forcing the
new checksum result to be saved. This will not get rid of the corruption in the data,
however.
After pressing the
SELECT
key on the above
menu page, you will arrive at the menu page
shown to the right. If you want to go ahead
with the procedure, press the
<yes>
SOFT KEY
.
Otherwise, press the
<no>
SOFT KEY
.
Now, you can assume that the "checksum
error" was no big deal, get a cup of coffee, and
go back to work (not advised), OR you can
assume something nasty is going on and take
immediate action (advised). Assuming you take the latter (smart) course of action, the
first thing you’ll want to do is to save all of your important programs, routing
configurations, and setups to a card (
see
Copying Programs
on page 132)
or to an external
storage device (
see
Dumping Data and Receiving Data Dumps
on page 146 ).
Then return to the
service
menu page in the
SETUP
area.
