Help with understanding current draw of MDS 9200

Unanswered Question
Mar 22nd, 2010

I have 3 MDS 9216A's which are on one circuit.  The circuit is a 20A circuit.

Please see the below output of "show envir power".  You will see that it shows 4.98A allocated to the Supervisor and 4.77A allocated to the SMIP.  To read this correctly, does that mean that the switch is requiring 4.98A, or that its actually requiring 10A?  I believe since its current, we would just need to go with the higher number, in which case each MDS is needing approx 5A.  Is this correct?
