 In former models (such as Ap/At-C3), there are some
SD card options that can't be merged.
 In Met-C1, there are no restrictions.
 For example, the part of the Postscript software that
requires licensing is now built into the controller, so the
portion on the SD card can be moved to another SD
card.
 You can insert SD card options in any slot on
controller board.
 We recommend that you insert SD card options in slot
1, because slot 2 is also used as the service slot.
