A non-standby PXM card is a standalone PXM card or the card
within a redundant PXM pair that is trying to go active. When
a non-standby PXM card is in a transitional state, such as the
init state, the PXM cannot transition to the standby state. When
all non-standby cards have reached a steady (non-transitional)
state, the PXM will transition to a steady state. Steady states are
as follows: active ready, failed, mismatch, empty, empty
reserved, and standby ready.
Note When either card in a redundant PXM pair is active, that
PXM pair is not preventing the standby PXM from
transitioning to a steady state. The standby PXM is only
affected when both cards in a redundant pair are in a
transitional state.
