Cisco Catalyst C1000-16P-E-2G-L 16-Port Managed PoE+ Switch, 2x1G SFP
The C1000-16P-E-2G-L is a 16-port PoE+ Layer 2 managed switch with 2x 1G SFP uplinks and an external power supply. It delivers 120W of PoE and supports Single IP Management.
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 C1000-16P-E-2G-L is the 16-port PoE+ configuration that draws from an external power adapter rather than an internal supply, which is the only difference from the internal-supply C1000-16P-2G-L. Its 120W shared PoE budget powers standards-compliant devices directly over the access ports, its two dedicated 1G SFP fiber uplinks aggregate to the distribution layer, and its fanless design runs silently outside a dedicated closet.
Technical Details
The Cisco Catalyst C1000-16P-E-2G-L is a Layer 2 managed fanless switch with 16 Gigabit Ethernet (10/100/1000) PoE+ ports and two fixed 1G SFP uplinks, running Cisco IOS and powered by an external power supply. Switching capacity is 36 Gbps and forwarding rate is 26.78 Mpps. It supports IEEE 802.3af PoE and 802.3at PoE+ up to 30W per port, sharing a 120W PoE power budget across the access ports. 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 powers and connects endpoints such as wireless access points, IP phones, and IP cameras in small-business and branch wiring closets.

Best For
The C1000-16P-E-2G-L suits small-business and branch sites that need to power endpoints such as wireless access points, IP phones, and IP cameras over 16 managed Layer 2 ports and prefer an external power supply for the installation. Its 120W PoE budget is suitable for a mixed deployment of powered devices, with actual device counts depending on each device's power draw, and its two 1G SFP fiber uplinks give aggregation to the distribution layer.
Not suitable if:
- you need a larger PoE budget than 120W, since a full set of higher-draw powered devices can exceed the shared budget
- 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 prefer a self-contained unit with an internal power supply

Part Number Decode
- C1000 — C1000 is the platform prefix, identifying a Cisco Catalyst 1000 Series Gigabit Ethernet model.
- 16 — 16 is the port count, indicating 16 access ports.
- P — P is the port-type marker, indicating PoE+ access ports served by a partial PoE power budget shared across the ports.
- E — E is the power-source marker, indicating the external-power-supply variant that draws from an external adapter rather than an internal supply.
- 2G — 2G is the uplink code, indicating two fixed 1G SFP uplinks.
- L — L is the standard model suffix Cisco uses across the Catalyst 1000 ordering line, not a selectable license tier.

FAQ
Does the Cisco Catalyst C1000-16P-E-2G-L support PoE, and how much power does it provide?
Yes. The Cisco Catalyst C1000-16P-E-2G-L supports IEEE 802.3af PoE and 802.3at PoE+ delivering up to 30W per port, with a 120W PoE budget shared across the 16 Gigabit Ethernet access ports. It can power devices such as wireless access points, IP phones, and IP cameras directly over the network cabling. The total number of powered devices depends on each device's power draw against the shared 120W budget.
What is the difference between the C1000-16P-E-2G-L and the C1000-16P-2G-L?
The two switches are identical in switching hardware: 16 Gigabit Ethernet PoE+ ports, a 120W PoE budget, two 1G SFP uplinks, Cisco IOS, and 36 Gbps of switching capacity. They differ only in power source. The C1000-16P-E-2G-L draws from an external power adapter, indicated by the E in the part number, while the C1000-16P-2G-L uses an internal power supply. Both are fanless. Choose the external-supply model where an external adapter suits the installation.
What transceivers do the uplinks on the C1000-16P-E-2G-L use?
The Cisco Catalyst C1000-16P-E-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 C1000-16P-E-2G-L be stacked?
No. The Cisco Catalyst C1000-16P-E-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 eases configuration and troubleshooting but is not a high-bandwidth stacked data plane.
Is the Cisco Catalyst C1000-16P-E-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 C1000-16P-E-2G-L units from inventory, and Cisco support continues under active service contracts through the Last Date of Support.
What condition is the C1000-16P-E-2G-L sold in, and what warranty applies?
The Cisco Catalyst C1000-16P-E-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.
