DCX Core Blade ICL ports

    On a DCX-8, does it make any difference to normal operation if the ICL ports on the core blades are enabled or disabled?  This is for a single chassis so the ICL's are not in use.  What is the best practice for these ports when not configured for ICL connectivity?

    I'd set the unused ports to persistent disabled state. They will not get allocated any buffers in this case and wouldn't wear their Tx/Rx circuits as well.

    Many thanks for the reply Alexey, that makes good sense about the buffers.  I don't see the TX/RX making a difference as it's a CR8 core blade, so doesn't have any SFP's if that's what you're refering to.

    That's right, but I think even copper ports do have some extra power consumption when they are enabled.
