Table 3: Module Slot Locations (continued)
Component
IOA
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:
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).
For information about working with modules and IOAs, see JunosE System Basics
Configuration Guide, Chapter 6, Managing Modules. See Table 4 on page 30 for currently
available IOAs and the bays in which you may insert them.
