48-Port 10G/40G Switch

The Cisco Catalyst WS-C3850-48XS is a managed Layer 3 switch with 48 ports supporting 10GBase-X and 40GBase-X speeds. It is built for enterprise networks that need high-density 10 Gigabit and 40 Gigabit connectivity in a standalone, rack-mountable form factor.

Sustained Load Behaviour

As a managed switch, it maintains consistent forwarding performance across all 48 ports under continuous traffic. The Layer 3 routing capability handles persistent IP traffic loads without degrading port throughput, making it suitable for core or aggregation layers with steady high-bandwidth demand.

Build and Connectors

The unit weighs 16.42 lb and fits standard racks for secure mounting. It ships with a power supply included. The 10G and 40G port interfaces require compatible transceiver modules and cabling, which dictate daily patching and uplink decisions in the rack.

Questions about this item

How loud or hot does the WS-C3850-48XS get when running 48 ports at 10G all day?

The 3850 series uses temperature-controlled fans; under full 10G load the chassis typically reaches moderate fan speed and stays within its rated thermal envelope.

Which SFP+ or QSFP+ modules must I already own to populate the 48 ports?

The switch accepts standard 10GBase-X SFP+ and 40GBase-X QSFP+ transceivers; you supply the optics that match your fibre type and distance.

Will my existing 1G copper uplinks negotiate down when plugged into this 10G/40G switch?

The WS-C3850-48XS provides only 10GBase-X and 40GBase-X ports, so 1G copper modules will not link; you need 10G or 40G optics for every connection.
