Populated Chassis Problems
Table 7 lists problems that may occur with a populated Expansion Chassis.

Make sure you power down the Expansion Chassis and the Macintosh whenever
you remove or add NuBus cards to your system. Changing cards or cables with
power to the chassis on causes the Expansion View utility to report unreliable
slot information.

Problem Solution
Macintosh doesn’t boot after installing
the Expansion Chassis and moving the
NuBus cards.
•
Power off the Macintosh and the Expan-
sion Chassis.
•
Remove the cover from the chassis or
open the cover if you have the 3D Effect
option installed (see Chapter 3, “Remov-
ing the Expansion Chassis Cover” on
page 29).
•
Remove the card guide assembly and the
PCB clamp.
•
Disconnect cables, as needed, and
remove NuBus cards from the chassis one
at a time. Power on the chassis and Mac-
intosh after each card is removed.
Note: If you need to remove the
card, the Advanced JPEG card and the
Enhancement card (if installed) do so in the
following order:
The card first
The Enhancement card second
The Advanced JPEG card third
Reinstall these cards in the reverse order.
•
After you find the problem card, reinstall
all the other cards and reconnect their
cables.
•
Power on the chassis and the Macintosh
to make sure that there are no other
problem cards.
•
Contact Avid Customer Support to con-
firm the problem card and obtain a
replacement.
Expansion View does not report the
interface card. See Table 5, “Interface Card Problems,” on
page 72.
