16 SFP ports and 8 Combo 10/100/1000BASE-T/SFP ports

The DGS-3120 Series xStack switches are enhanced L3 Gigabit switches designed to connect end-users in a secure SMB or enterprise network. These switches support physical stacking, multicast, and enhanced security, making them an ideal Gigabit access layer solution. The DGS-3120-24TC/48TC provides 20 or 44 10/100/1000 Mbps Gigabit Ethernet ports, and 4 combo 1000BASE-T/SFP Gigabit Ethernet ports. The DGS-3120-24PC/48PC provides 24 or 48 10/100/1000 Mbps PoE Gigabit Ethernet ports and 4 combo 1000BASE-T/SFP Gigabit Ethernet ports. The DGS-3120-24SC/24SC-DC provides 16 SFP Gigabit Ethernet ports and 8 combo 1000BASE-T/SFP Gigabit ports. Each 10/100/1000 Mbps port on the DGS-3120-24PC/48PC supports the 802.3af and 802.3at Power over Ethernet standards. The default power budget for these models is 370 watts and can be expanded to 760 watts with the DPS-700 RPS. The switches are also equipped with an SD Card slot, allowing the user to boot images and upload configuration files directly from an SD Card as well as conveniently save syslog files onto the SD Card.
