OCPRF100 MP Server System Technical Product Specification

Revision 1.0

8.7.5CONN_MODE

This becomes the TMS input on the JTAG ports of all the PLDs. TMS is a mode select pin which controls the function of the JTAG port. If the enable signal is high (i.e., disabled), the mode signal is degated from the TMS pin, and TMS is held high, which keeps the JTAG port in an idle state.

8.7.6CONN_SCLK

This is connected to the TCK clock input on the JTAG port of all the PLDs.

8.8Electrical, Mechanical Specifications

This section specifies the operational parameters and physical characteristics for the backplane.

8.8.1Connectors

This section defines all the major connectors on the backplane. All the connectors on the backplane are keyed.

8.8.1.1Connector Specifications

Table 8-6: Connector Specifications shows the quantity, manufacturer, and Intel part number for connectors on the backplane. Refer to manufacturers’ documentation for more information on connector mechanical specifications.
