5-2 Troubleshooting and maintenance
Meridian Mail Card Option Release 9.0
Suppose a portion of a procedure reads as follows:
The first three steps do not—as it first might appear—instruct you to ensure
that the power is on and then to turn it off. Rather you should first ensure that
the main Meridian 1 power is on. If turning it on does not clear the problem,
then ensure that the Meridian Mail power switch is on. If this still does not
clear the problem, only then should you proceed to step 3. In this case, it in-
structs you to turn off the power before touching the Connector Board.
Unless otherwise stated, an instruction that tells you to replace a component
implies that you should then reinstall and restart Meridian Mail to see if the
problem has cleared. If replacing the component does not clear the problem,
you should reinstall the old component and proceed to the next step in the
troubleshooting procedure. For example, the following procedure:
does not instruct you to replace all of the Meridian Mail cards. Rather, you
should first try replacing the 68k Card, reinstalling the rest of Meridian Mail
and restarting the system. If this does not solve the problem, you should rein-
stall the old 68k Card and try replacing the DVP Card. If this still does not
solve the problem, you should reinstall the old DVP Card and try replacing
the Disk/Power Supply Card.
Precautions
You must not remove or handle any of the Meridian Mail hardware while Me-
ridian Mail is on and running. If the switch on the 68k Card is on, follow the
procedure for stopping Meridian Mail on page 4-5. Failing to do so can result
in damage to the components or injury to yourself.
1 Ensure that the main Meridian 1 power supply is on.
2 Ensure that the Meridian Mail power switch on the 68k Card is on.
3 Turn off the Meridian Mail power switch on the 68k Card, and en-
sure that the Connector Board is properly seated.
1 Replace the 68k Card.
2 Replace the DVP Card in slot MM2.
3 Replace the DVP Card in slot 9.
4 Replace the Disk/Power Supply Card.
