Module Configurations
PXM45 card redundancy is preconfigured on the Cisco MGX switches. If PXM45 cards are inserted in
both slots 7 and 8, they automatically operate as redundant cards. If you install only one PXM45 in the
switch, it operates as a standalone card. It is recommended that you install two to provide fault tolerance
for the PXM45. If one card goes down, a redundant card takes over.
For the cards to operate redundantly, Y-cabling must be present on the external clock ports on the
Note
back cards.
