Be careful with the two fibers from the last Hub Filter module. Those fibers must be
terminated, either by installing a new TM or inserting a BM, a CMX, or a CMY module.
To lock the TM effectively, you must slide the TM on the bottom of the passive optical shelf.
Failure to do so may cause the TM to pop up. If popped up, the TM will not align properly
with the rest of the modules.
