The Alternate Function Dip Switch; Eeprom Loading - Magma EB7-X8G2 User Manual

Magma

The Alternate Function DIP Switch

The Alternate function DIP switch controls the following three functions: Hot Plug, Clock and power delivery behavior.
Actuator (1) Hot Plug:
Turns the Hot Plug function ON and OFF. Its default position is Enabled in which case a Hot Plug controller supervises
power delivery to the PCIe slots.
Actuator (2): Local Clock:
Turns on a local clock generated by the chassis itself independent of that of the Host system. Its default position is
Disabled, i.e. the system Clock comes from the Host system (uplink).
Actuator (3): Slot Clock
Should be enabled only when a PCIe CPU card is placed in the 7 slot. That way a locally-generated clock can be
th
supplied to the card.
Actuator (4): For Magma internal use.

EEPROM Loading

The core component in the expansion chassis—the PCIe switch— requires EEPROM loading of code for proper operation
in PCIe Gen II mode. Therefore in an EB7x8G2 system, which supports Gen II speeds, J16 must be installed. In case of the
EB7x8 system, J16 may remain open.
