Cisco SR224G 24-Port 10/100 2-Port Gigabit Switch + 2 Mini-GBIC Cisco Small Business Unmanaged Switches Speed and Flexibility to Connect Small Businesses Highlights ● Connect up to 24 devices: PCs, printers, and wireless access points with auto-sensing ports ● Multiple high-speed options to connect to the network backbone ● Works right out of the box with no software to configure ● Suitable for rack-mount installation Product Overview The Cisco(r) SR224G 24-Port 10/100 2-Port Gigabit Switch + 2 Mini-GBIC (Figure 1) delivers nonblocking, wire-speed switching for your 10/100-Mbps network clients, plus multiple options for connecting to your network backbone. Twenty-four 10/100 ports wire up your workstations, while the integrated 10/100/1000 ports or mini Gigabit Interface Converter (mini-GBIC) ports connect to your servers or backbone at Gigabit speeds. The Cisco SR224G incorporates nonblocking, wire-speed architecture that forwards packets as fast as your network can deliver them. It features broadcast storm suppression that maximizes the system availability. Also included are Address Learning and Aging to prevent data transfer errors and Data Flow Control to help prevent packet loss. All ports have automatic medium dependent interface (MDI) and MDI crossover (MDI-X) detection, so you dont have to worry about the cable type. Each port independently and automatically negotiates for best speed and whether to run in half- or full-duplex mode. Head-of-line blocking prevention keeps your high-speed clients from bogging down in lower-speed traffic, and fast storeand- forward switching prevents damaged packets from being passed on to the network. No matter how intensive your network demands, the Cisco SR224G 24-Port 10/100 2-Port Gigabit Switch + 2 Mini-GBIC has speed, flexibility, and reliability that you can count on Features ● Ideal for integrating your 10-Mbps and 100-Mbps network hardware ● Twenty-four 10/100 ports provide dedicated bandwidth in half- or full-duplex modes ● 2 Gigabit Ethernet ports and 2 shared mini-GBIC slots for Gigabit fiber expansion ● Each port supports auto MDI/MDI-X cable detection ● Compatible with all major network operating systems ● Advanced store-and-forward packet switching optimizes data transfers ● Auto partitioning protects PCs from downed network lines ● Signal regeneration ensures data transfer integrity Specifications Table 1 contains the specifications and package contents for the Cisco SR224G 24-Port 10/100 2- Port Gigabit Switch + 2 Mini-GBIC.
