Installing Expansion Cards
3.
Remove the side panel and locate either the PCI Express or the PCI slot as shown in the
image below.
4.
Loosen the thumbscrew on the back of the enclosure and remove the bracket holding the PC
brackets in place. The bracket is keyed and may have to be rocked back and forth to remove.
5.
If installing multiple expansion cards, install the PCI Express card first due to the tight
confines of the enclosure.
6.
Align the expansion card with the proper slot and press the card into the slot until firmly
seated.
7.
On the outside of the enclosure, replace the bracket with thumbscrew and tighten securely
by hand. The image shows two expansion cards properly installed.
