D-Link DEM-540 4-Port Stack Module for DGS-3212SR

Product Features:• IEEE 802.3 compliance
• 1 transmitting port and 1 receiving port
• Up to 1.2Gbps dedicated stacking bandwidth

Product Description:DEM-540 is a 4-port stacking Module designed for D-Link L2⁄L3 switch such as DGS-3212SR and DGS-3312SR. The DGS-3212SR is the stacking master unit for the DES-3226SM. The DGS-3312SR is the stacking master unit for the DES-3326SRM. Each DEM-540 stacking Module supports up to four DES-3226SM or DES-3326SRM stackable switches. With two DEM-540 4-port stacking modules, up to eight stackable switches can be stacked together, which will provide 192 10⁄100Mbps Fast Ethernet ports and 12 Gigabit Ethernet ports in a stack.
