Extreme Networks has pushed 10/100M-bps switching forward by cramming 48 ports into a 1U form factor, along with advanced security and traffic management features including ACLs and QOS. This is a good switch for the wiring closet, especially for shops that already have Extreme in the core of the network, because the "i" chip set uses the same operating system and extends future-proofing capacity with eight hardware queues for granular traffic management.
LONG-TERM BUSINESS IMPACT // Over time, the Summit 48si should enable IT managers to ration bandwidth in such a way that high-priority traffic consistently receives the most attention. PROS // High port density; 1U form; hot-swappable, dual power supply; advanced QOS and security features. CONS // Multiple units can be daisy-chained together but not as one stackable unit.

SHORT-TERM BUSINESS IMPACT // The Summit 48si should immediately provide greater control over access to the network while also putting more port density into the wiring closet, thereby improving security while saving valuable rack space.
