Switching between Standard, High Speed, and Initiator/External MIX mode
Channel adapter boards (PCB: printed circuit board) take Standard, High Speed, or Initiator/External
MIX mode. You can apply High Speed mode to channel adapters to improve system performance. Or
you can apply Initiator/External MIX mode so that one port can be used both as an initiator port for
Continuous Access XP or Continuous Access XP Journal and as an external port applied to a remote
command device. Be aware that you can only apply High Speed or Initiator/External MIX mode to
channel adapters that satisfy certain requirements. For more information, see Standard, High Speed,
