The 3Com SuperStack 3 Switch 3300 XM (SKU 3C16985B) is a fixed configuration Layer 2 Ethernet switch designed for enterprise networks. It features 24 autosensing 10/100BASE-TX RJ-45 ports supporting full/half duplex operation and 1 matrix stacking connector, enabling stacks of up to 4 switches for a 96-port virtual switch. Management options include an embedded web server, SNMP, Telnet, RMON, and 3Com Network Supervisor. Protocols supported encompass IEEE 802.1p prioritization, IEEE 802.1Q VLANs, IGMP snooping, and IEEE 802.1D Spanning Tree. The store-and-forward switching method with elastic buffering optimizes performance. Physical specs include 1U rackmount form factor (1.7in H x 17.3in W x 9.7in D), DB9 console port, and 90-240 VAC power input. Status LEDs indicate port link/activity/speed and system status. Ideal for expanding Ethernet infrastructure with stacking compatibility to SuperStack II/3 units.
