Installing a Universal Feature Card
The following instructions describe how to install a UFC in the 8270.
Note: The following illustrations show installing a UFC in an 8270-800, however
installing a UFC in an 8270-600 is similar. If you are installing a UFC in a slot that
is currently unoccupied you might not have to reconfigure the 8270. If you are
replacing an existing UFC, it must be replaced with one of the same type or
reconfiguration will be required.
Follow these steps to install UFCs:
Step 1. Remove the UFC and all accompanying documentation from the shipping
container.
Step 2. Read all of the documentation provided with the UFC before installing it in
the 8270.
Step 3. If the 8270 is powered on, power it off before installing the UFC.
Step 4. Remove the blank cover from the UFC slot in which the UFC is to be
installed from the front of the 8270. To remove the cover, remove the
two thumbscrews holding it in place, then grasp the edge of the cover
and pull it out of the slot. See Figure 2-9 on page 2-16. Retain the
cover and the thumbscrews for use in the event that the UFC is ever
removed.
Notes:
a. The 8270-600 is shipped with no cover on UFC slot 1. The first UFC
that is installed in the 8270-600 should be placed in slot 1.
b. The 8270-800 is shipped with no cover on UFC slot 8. The first UFC
that is installed in the 8270-800 should be placed in slot 8. If
possible, avoid installing a UFC with more than 2 ports in UFC slot 1.
If a 4-port UFC is installed in slot 1, ports 3 and 4 will not operate.
