Caution –
If you install a PCI card when the External I/O Expansion Unit is
running, be prepared to complete the installation within two minutes or so. If you
leave a carrier slot empty, the External I/O Expansion Unit might overheat.
New carriers include dummy cards. The dummy cards help the carriers to stay in
place and to control the passage of air through the I/O boat. For information about
dummy cards, see
