Figure 1.5: CHAMP-AV8 SRIO Port Connections
Note
SRIO connections do NOT auto-negotiate their link operating speed if different generations
of SRIO are mixed. For example, when mixing older hardware boards such as the VPX6-185
or the CHAMP-AV6 (which support Gen 1 speed, 3.125 Gbaud) with the CHAMP-AV8
(defaults to Gen 2, 5.00 Gbaud, but supports 3.125 Gbaud) the off-board SRIO link speed
must be set to values supported on both boards. In this case the CHAMP-AV8 would be
down-graded to the Gen 1 speed. See the BIOS User's Manual, Curtiss-Wright document
826450, for more information.
