Double wide switch blade for the new c7000 enclosure with 16 downlink ports to connect server
blades via the midplane. and 16 QSFP unlink ports for the inter-switch links or to connect to
external servers. All ports are capable of supporting 40Gbps (QDR) bandwidth. All uplink ports
support copper and fiber optic cables. The switch is externally managed, i.e. a subnet manager
