8.0Test Points
8.1Reset Test Points
Two test points allow evaluation of the IXF1110 reset signals. TP21 allows IXF1110 Sys_Res signal monitoring. DTP3 allows board reset signal monitoring. The board Sys_Res can be monitored on both test points if it is asserted by Switch S1 or the CPU. The reset is seen at TP21 if an IXF1110 reset is issued by the software interface.

8.2IXF1110 Input Clock Test Points
The IXF1110 requires input clocks of 50 and 125 MHz. There are two test points that allow the user to monitor those signals (see Table 6).

8.3GBIC Test Points
Table 7 lists GBIC test points that allow evaluation of the I2C clock, which is connected to all of the GBIC modules, and the I2C Data pins for each of the ten ports. For more information on the I2C interface, refer to the IXF1110 Datasheet.
