Cisco Catalyst C1000-16T-2G-L 16-Port Managed Data Switch, 2x1G SFP
The Cisco Catalyst C1000-16T-2G-L is a 16-port Layer 2 managed switch with 2x 1G SFP uplinks. It supports Single IP Management for up to eight switches in a single stack.
Overview
Cisco Catalyst 1000 Series switches are fixed managed Gigabit Ethernet Layer 2 switches for small businesses and branch offices, built for out-of-the-wiring-closet and IoT deployments and administered through Cisco IOS using a CLI, an on-box web UI, and Bluetooth over-the-air console access. The C1000-16T-2G-L is the 16-port data-only configuration in this line, with two dedicated 1G SFP fiber uplinks for aggregation back to the distribution layer. Unlike the 8-port models, its uplinks are SFP fiber ports rather than SFP/RJ-45 combo ports, so uplink connectivity is over transceivers. Its fanless design runs silently for placement outside a dedicated closet, and it forwards traffic at Layer 2 only, without routing.
Technical Details
The Cisco Catalyst C1000-16T-2G-L is a Layer 2 managed fanless switch with 16 Gigabit Ethernet (10/100/1000) data ports and two fixed 1G SFP uplinks, running Cisco IOS. Switching capacity is 36 Gbps and forwarding rate is 26.78 Mpps. It carries no Power over Ethernet, so all 16 access ports are data-only. It provides no data-plane stacking, though the Gigabit Ethernet uplinks support Cisco Single IP Management of up to eight switches under one IP address. It connects non-powered endpoints such as desktops, printers, and wired IoT devices in small-business and branch wiring closets.

Best For
The C1000-16T-2G-L suits small-business and branch wiring closets that connect non-powered endpoints such as desktops, printers, and wired IoT devices and need managed Layer 2 switching with Cisco IOS across 16 ports. Its two 1G SFP fiber uplinks aggregate to the distribution layer, and its fanless design fits quiet, closet-free spaces.
Not suitable if:
- you need to power devices such as wireless access points, IP phones, or IP cameras, since this is a data-only switch with no Power over Ethernet
- you need more than 16 access ports, since this is a 16-port model
- you need 10G uplinks, since the two uplinks are fixed 1G SFP ports
- you need a copper RJ-45 uplink, since the two uplinks are SFP fiber ports without a combo copper option
- you need Layer 3 routing, since this switch operates at Layer 2 only

FAQ
Does the Cisco Catalyst C1000-16T-2G-L support PoE?
No. The Cisco Catalyst C1000-16T-2G-L is a data-only switch, and all 16 Gigabit Ethernet access ports carry no Power over Ethernet. It cannot power devices such as wireless access points, IP phones, or IP cameras. If you need PoE+ on the access ports, the Cisco Catalyst C1000-16P-2G-L is the matching 16-port PoE+ model with a 120W PoE budget and the same two 1G SFP uplinks, and the C1000-16FP-2G-L offers a larger 240W PoE budget.
What transceivers do the uplinks on the C1000-16T-2G-L use?
The Cisco Catalyst C1000-16T-2G-L has two fixed 1G SFP uplink ports. These are 1-Gigabit SFP fiber slots, not SFP/RJ-45 combo ports, and they do not support 10G SFP+ optics. Specific transceiver compatibility should be verified against the manufacturer's transceiver compatibility matrix at tmgmatrix.cisco.com. Transceivers are sold separately.
Can the C1000-16T-2G-L be stacked?
No. The Cisco Catalyst C1000-16T-2G-L does not provide data-plane stacking, so there is no shared switching fabric across units. As a Gigabit Ethernet model it does support Cisco Single IP Management, which uses the uplink ports to connect up to eight switches so they can be managed under a single IP address. This is a management convenience for configuration and troubleshooting, not a high-bandwidth stacked data plane.
What is the difference between the C1000-16T-2G-L and the C1000-16T-E-2G-L?
The two switches are identical in switching hardware: 16 Gigabit Ethernet data-only ports, two 1G SFP uplinks, Cisco IOS, and 36 Gbps of switching capacity. They differ only in power source. The C1000-16T-2G-L uses an internal power supply, while the C1000-16T-E-2G-L draws from an external power adapter. Both are fanless. Choose the internal-supply model for a self-contained unit and the external-supply model where an external adapter suits the installation.
Is the Cisco Catalyst C1000-16T-2G-L end of life?
Cisco has published an End-of-Sale and End-of-Life notice for the Cisco Catalyst 1000 Series. The last day to order from Cisco was April 30, 2025, and the Last Date of Support is April 30, 2030. Network Devices Inc. sells new, factory-sealed C1000-16T-2G-L units from inventory, and Cisco support continues under active service contracts through the Last Date of Support.
What condition is the C1000-16T-2G-L sold in, and what warranty applies?
The Cisco Catalyst C1000-16T-2G-L is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
