The 3Com Baseline Switch 3C16477A is a 1U rack-mountable, web-managed Layer 2 Ethernet switch engineered for small to mid-sized network deployments. This 24-port configuration combines 10/100 Mbps Fast Ethernet ports with dual-purpose Gigabit uplinks supporting both copper (10/100/1000BASE-T) and SFP fiber connectivity. The switch delivers non-blocking, wirespeed switching with an 8,192-entry MAC address table and supports up to 512 port-based VLANs per IEEE 802.1q standards. Link aggregation enables manual grouping of up to 8 ports across 6 trunks for increased bandwidth.
