Connectivity between blades and interconnect modules

The c-Class server blades use mezzanine cards to connect to various network fabrics. The connections
between the mezzanine cards on the server blades and the interconnect modules are through
independent traces on the NonStop signal midplane.
Connections differ depending on the enclosure. The c7000 enclosure was designed for
fully-redundant connections between the server blades and interconnect modules. As an example,
Figure 8 shows how c-Class half-height server blades in the c7000 enclosure connect redundantly to
the interconnect bays. The c3000 enclosure, on the other hand, was focused on a mid-market
customer that often does not require full redundancy. With the c3000 enclosure, customers can use
either a single Ethernet switch or redundant Ethernet switches in interconnect bays 1 and 2. Figure 9
gives an example of how c-Class half-height server blades connect to the interconnect bays in the
c3000 enclosure.
Customers should review the appropriate user guide for each enclosure. The guides are available at
