48-Port 10/100 Managed Layer 3 Switch

The D-Link DES-3852 is a rack-mountable managed Layer 3 switch with 48 Fast Ethernet ports, two combo SFP/1000BASE-T ports and two built-in 1000BASE-T uplinks. It supports up to 4K static and 255 dynamic VLANs, 802.1p priority queues and 16K MAC addresses. Aggregated bandwidth reaches 17.6 Gbps with a 32 MB buffer and jumbo frames up to 9 KB.

Suited for Fast Ethernet edge deployments needing

This switch fits networks where 48 10/100 endpoints must be aggregated through Gigabit uplinks and static IP routing is required. It is not for environments that need full Gigabit to every desktop, Power over Ethernet, 10 GbE uplinks, or stacking beyond the listed 32 link-aggregation groups.

17.6 Gbps aggregated bandwidth with 32 MB buffer

The single figure that decides fit is the 17.6 Gbps aggregated switching capacity combined with 32 MB packet buffer. If your design demands higher total throughput or deeper buffering for bursty traffic, this model will not meet that requirement.

Questions about this item

What cabling is required for the 48 10/100 Mbps ports on the DES-3852?

The 48 ports use copper Ethernet cables and operate at 10/100 Mbps speeds.

Can the DES-3852's Gigabit uplinks connect to older 10/100 switches?

The two built-in 1000BASE-T uplinks and two combo SFP/1000BASE-T ports auto-negotiate down to 10/100 Mbps for legacy links.

Which front-panel LEDs confirm the DES-3852 is operating normally after power-up?

The Power LED shows the internal 100-240 VAC supply is live, while each port's Link/Act/Speed LED indicates an active, error-free connection.
