Historically, the work section that I am a part of has requested RMAs for C4500 power supplies, as 1 RMA (up to two PS's) per chassis SN, and then never using that chassis to commit an RMA again. However, this seems strange to me, in that if I committed the same number of RMAs as there were chassis, then I would have no more chassis to commit any future such RMA.
I have the theory that my section mates and I have been taught incorrectly in this, as it would seem that we could submit future RMAs on a given chassis' components equal to the number of components it has, at an indefinite amount... presupposing that all RMAs are fully completed in a given event.
Is my theory true? Can we re-use previously used chassis SNs for RMAs of previously received replacement devices that have later gone bad?
Thank you for any assistance/clarifications.
