I/O Modules
The I/O Modules (IOMs) support either a Fabric A/B interconnect or a Fab-C interconnect. The Fab A/B IOMs span the entire
width of the chassis, using direct orthogonal connections to the compute sleds. When installing these, the IOM will engage
simultaneously with the Vertical PDB and the sleds. .
The Fab C IOMs span one half of the chassis width, installing side by side in the back of the chassis. These IOMs plug directly into
the Main DB using three high density right-angle connectors.
Power Supplies
The MX7000 Power Supplies(PSUs) utilize a new front-loading form factor. Up to six PSUs plug into the front of the chassis. These
mate directly with connectors on the Main Distribution Board (DB). The AC connections come from the rear of the chassis cabling to
connections on the Power Distribution Board (PDB).
Fans
There are two different types of fan module used in the MX7000 chassis, 60mm fans in the front and 80mm fans in the rear. Each
fan is enclosed in a mechanical assembly to make up the module. The fan modules are hot-swappable, with 3+1 redundancy for the
front fans, and 4+1 redundancy for the rear fans. The system should always be populated with the full set of fans to support the
airflow requirements of the chassis.
