7. Typical Deployment Scenarios

• Small enterprise all-Gigabit office access layer switch: 24 Gigabit copper ports connect employee workstations, servers and Cisco IP phones; fixed copper design eliminates fiber transceiver costs for short-distance trunking to building core switches
• Education classroom & lab Gigabit aggregation: Cluster multiple WS-C2970G-24T units to scale student workstation port density, copper trunk links connect to campus distribution switches over Cat6 cabling
• Small remote branch office wiring closet core switch: All-copper fixed design simplifies deployment for sites without fiber backhaul infrastructure
• Small retail back-office aggregation: Compact 1RU rack footprint for limited IT rack space, Gigabit ports for POS terminals and staff PCs
• Legacy office network upgrade: Direct replacement for 10/100 2950 series switches to deliver full Gigabit bandwidth without rewiring existing copper cabling
