  1. Bhavesh

    S6720-26Q-SI-24S arrived at long time ago, now we start to configure due to COVID-19, can I configure 2 to 1 VLAN Mapping on this switch?

  2. Chepera

    Reasonable price, I bought extra AC power module for spare; now we plan to order S6720-30C-EI-24S, is the extra AC module suitable for S6720-30C?
