Stand-Alone Operating Mode (J8)

The MCPN750A has a stand-alone operating mode that allows the MCPN750A to function without the clock from the system slot controller board. Installing a jumper across pins 1 and 2 of J8 enables the stand-alone mode. The J8 jumper must be removed for normal operation.

(Factory Configuration)

Note An MCPN750A configured for stand-alone mode should not be installed in a chassis with a system slot controller board. This will result in unpredictable system operation. See the section on System Considerations for additional information.
