Description

The Catalyst 3850 12-port SFP switch is a 1 RU stackable Layer 3 access and aggregation switch built for fibre-based downlink aggregation. It suits enterprise campus access, branch offices, EMI-sensitive or secure fibre deployments, and converged wired and wireless access with integrated wireless controller capability.

It provides 12 Gigabit Ethernet SFP downlink ports with 68 Gbps switching capacity and a 50.5 Mpps forwarding rate. Optional uplink modules (C3850-NM-4-1G or C3850-NM-2-10G) add further uplink capacity. This SKU ships with the IP Services feature set, which adds advanced Layer 3 routing for IPv4 and IPv6, and a default 350WAC power supply (PWR-C1-350WAC) with a second bay for a redundant supply. It is a data-only model with no PoE. StackWise-480 stacking provides 480 Gbps of stack bandwidth, and StackPower shares power across stack members.

The SFP receptacles accept Gigabit SFP modules. Stacking uses STACK-T1-50CM, STACK-T1-1M or STACK-T1-3M cables, and StackPower uses CAB-SPWR-30CM or CAB-SPWR-150CM cables.

FAQs

Q: Which licence does this switch ship with?
A: The -E suffix means it ships with the IP Services feature set. Feature sets are LAN Base, IP Base and IP Services, and mixed stacks of different feature sets are not supported. Cisco DNA Essentials and Advantage term licences are optional add-ons.

Q: Does it support PoE?
A: No. This is a data-only model with no PoE capability. It runs from a 350WAC power supply (PWR-C1-350WAC), and a second bay accepts a redundant supply.

Q: Which uplink modules does it support?
A: It supports the C3850-NM-4-1G and C3850-NM-2-10G uplink modules. The 4-10G, 8-10G and 2-40G modules are not supported on this model.

Q: What can the SFP ports accept?
A: The 12 downlink SFP receptacles accept Gigabit SFP modules only. Optics compatibility is listed in Cisco's transceiver compatibility matrix.

Q: How do I stack it with other switches?
A: Use StackWise-480 cables (STACK-T1-50CM, STACK-T1-1M or STACK-T1-3M) for data stacking and CAB-SPWR-30CM or CAB-SPWR-150CM for StackPower. Switches in a stack must run the same feature set.

Q: Which power supplies can go in the second bay?
A: The second bay supports a redundant 350WAC, 715WAC, 1100WAC or 440WDC power supply.
