Network Module for Catalyst 3850

The EVESKY C3850-NM-4-1G is a 4-port Gigabit Ethernet network module designed for Catalyst 3850 series switches. It adds four 1GE ports to compatible chassis, expanding wired connectivity for enterprise access-layer deployments. The module is field-replaceable and supports hot-swappable installation without powering down the switch.

Capacity and Headroom

Four 1GE ports provide line-rate copper connectivity for endpoints such as IP phones, wireless access points, and workstations. The module handles standard Gigabit traffic loads but does not offer multi-gigabit or fibre uplinks. Throughput is limited to the 1GE per port ceiling, so bandwidth-intensive uplinks require a different module.

Build Integration

The module slides into the network module slot on Catalyst 3850-12, 3850-24, 3850-12X48, or 3850-48 switches. No additional cabling or external power is needed beyond the switch chassis. It frees up fixed ports on the base switch for other connections while keeping the stackable architecture intact.

Highlights

  • Adds four Gigabit ports to Catalyst 3850 switches
  • Hot-swappable module installs without powering down the chassis
  • Supports PoE+ for powering phones and access points
  • Net weight .6 kg keeps rack load light
  • Compatible with 12, 24 and 48 port 3850 models

Questions about this item

Will the C3850-NM-4-1G module fit in the Catalyst 3850-12X48 switch I already run?

Yes — the module is listed for the 3850-12X48, 3850-48, 3850-24 and 3850-12 chassis, so it slots straight into your existing switch.

How can I verify the four GigE ports are active after installation?

Check the front-panel link LEDs on each of the four ports; a solid green light means a live 1 Gb/s connection, while blinking shows traffic passing.

Does the box include patch cables or SFP transceivers, or must I buy them separately?

The package contains only the network module itself (net weight .6 kg, package weight 1.61 kg); copper patch cords or SFP modules for the four ports are not included.
