I would think spares would need to be stored at the operational altitude. =
If I'm not mistaken, if they are at a different average altitude, the =
orbital planes will begin to shift. If the altitude difference is small, =
the plane change would be small. The satellites might have enough fuel to =
change the orbital plane, however much it had changed, when it needs to =
be activated.

The Iridium spares were planned to be "stored" in a 668 km high orbit in
each of the respective planes. I think the satellites to date have been
boosted to the operational altitudes, but you elset people would know
better than I.

Hope this helps.
