Step 2: Checking the Jumper and Switch Settings

At the factory, all jumpers and switches on the Model 78861 are installed in default positions. The default parameters selected may or may not meet your requirements.

Model 78861 includes one Pentek 78861 XMC module mounted on a Pentek Model 7807 XMC to PCIe carrier. The shorting jumpers used on Model 78861 are for 0.020" (0.51 mm) square pins spaced on 0.079" (2.00 mm) centers. These jumpers are NorComp part number 810−002−LP1R001, or equivalent. Pentek’s part number for these jumpers is 356.00015.

Before installing Model 78861, review the following topics to determine whether you need to change any settings:

• DIP Switch Settings
• PCIe Carrier Jumpers
• PCIe Carrier Switches

If you need to access the jumpers or switches on the PCIe carrier, you must first remove the XMC module from the PCIe carrier, as shown in Removing the XMC Module from the PCIe Carrier.

You should only change the jumpers and switches that are described in the above topics − all others are reserved for factory test and setup purposes only.
