IOA Slot Combinations

Depending on the software release and IOA type, you must install IOAs in certain
slots and bays combined with other IOAs in the same slot:
For information about working with modules and IOAs, see JUNOSe System Basics
Configuration Guide, Chapter 6, Managing Modules. See Table 4 on page 32 for currently

IOA
You must insert some IOAs only in the upper bay or right bay (Adapter 0) of
each IOA module slot. If you insert one of these IOAs into a lower bay or left
bay (Adapter 1) slot, the line module diagnostics fail, an error message states
that the bottom slot is not supported for the currently installed software release,
and the slot is disabled.
If you insert an unrecognized IOA, such as an IOA that is not supported by a
particular software release, the line module diagnostics fail, an error is generated,
and the slot is disabled.
If you remove an IOA and replace it with a different IOA in the same slot, an
error message states the mismatch and the slot is disabled.
Full-height IOAs take up the entire slot (both Adapter 0 and Adapter 1).
