To install a PCI device, complete the following steps:
1. Power off and unplug the PC.
2. Remove the PC cover.
3. Insert the device into an open PCI slot as shown in Figure 3.

Tip To maximize airflow and extend the life of the PCI device, leave any adjacent PCI slots empty.
(NI PCI-5911) When you install the NI PCI-5911, verify that the BNC connector is centered in the
metal frame of the chassis, as shown in Figure 4. Signal degradation can occur if the outer shell of
the BNC connector touches the computer chassis. To minimize noise, do not allow the shell of the
BNC connector to touch or lie near the metal on the PC.

Multiple NI 5911 devices in the same computer can raise operating temperatures beyond
specification and produce imprecise data. NI strongly recommends leaving an empty PCI slot
between multiple NI 5911 devices or adding a fan.
