Section 5 Maintenance and Alignments
Maxiva ULX COFDM Series
STEP 5
Push evenly on the front of front of the module with a slight side to
side motion to help align the mating connectors.
STEP 6
Use firm, moderate pressure to fully seat the module
. If the module
fails to seat with moderate pressure do not force the module into the
rack. Remove the module and inspect for interference.
NOTE:
In some cases it has been noted that it can be difficult to reinsert a hot PA module.
If the connection is difficult (module doesn’t seat fully with moderate pressure)
simply allow the module to cool sufficiently before reinserting.
Check the coolant connectors on the back of the PA module and on the coolant
manifold. The manifold connector has an O-ring seal (Figure 5-2) which must be in
good condition to prevent leaks. If there is evidence of a mechanical interference or
misalignment of the coolant connectors on all the modules then a rack re-alignment
may be required. This may be required if a manifold is replaced. The rack realignment
helps align the coolant connectors in the manifold with the coolant connectors on the
PA modules. If rack alignment is needed refer to 5.2.5 on page 5-6.
