The Nexus 2348TQ is a low-power platform that is well suited for migration to 10GBASE-T. It supports high-density 100 Megabit Ethernet and 1 and 10 Gigabit Ethernet environments and has 48 x 100MBASE-T and 1/10GBASE-T host interface (HIF) ports as well up to six 40-Gbps uplink ports to the parent switch. The 40-Gbps uplinks support BiDi optics for simple connectivity using your existing cable plan, while lowering power and solution costs. The Cisco Nexus 2348TQ supports FCoE.
Support for both forward (port-side exhaust) and reverse (port-side intake) airflow schemes is available. Forward airflow is useful when the port side of the switch sits on a hot aisle and the power-supply side sits on a cold aisle. Reverse airflow is useful when the power-supply side of the switch sits on a hot aisle and the port side sits on a cold aisle. The Cisco Nexus 2348TQ has two 1+1 redundant hot-swappable power supplies and three hot-swappable independent fans with support for 2+1 redundancy.
The fabric extenders can be used in the following deployment scenarios:
● Rack servers with 100 Megabit Ethernet, 1 Gigabit Ethernet, or 10 Gigabit Ethernet network interface cards (NICs); the fabric extender can be physically located at the top of the rack, and the Cisco Nexus parent switch can reside in the middle or at the end of the row, or the fabric extender and the Cisco Nexus parent switch can both reside at the end or middle of the row
● 10 Gigabit Ethernet and FCoE deployments, using servers with converged network adapters (CNAs) for unified fabric environments
● 100MBASE-T and 1/10GBASE-T server connectivity with ease of migration from 100MBASE-T to 1GBASE-T to 10GBASE-T and reuse of structured cabling
● 1 and 10 Gigabit Ethernet blade servers with pass-through blades
● SAN connectivity (2348UPQ with 5600 only)
● Low-latency, high-performance computing environments
● Virtualized access
