I/O Modules are used as pairs, with two modules servicing each server module fabric providing a fully
redundant solution. I/O Modules may be passthroughs or switches. Passthrough modules provide
direct 1:1 connectivity from each LOM/mezzanine card port on each server module to the external
network. Switches provide an efficient way to consolidate links from the LOM or Mezzanine cards on
the server modules to uplinks into the customer's network.
