Cisco Catalyst C1000-24T-4G-L - 24-Port Gigabit Ethernet Switch | 4x 1G SFP Uplinks | Layer 2 Managed | Fanless - Cisco Refresh

The Cisco Catalyst C1000-24T-4G-L is a fixed managed Layer 2 Gigabit Ethernet switch built for small businesses, branch offices, classrooms, and IoT deployments that need reliable, secure, enterprise-class LAN connectivity. It delivers 24x 10/100/1000 Ethernet ports (RJ-45) plus 4x 1G SFP fiber uplinks, with a 56 Gbps switching capacity and 41.67 Mpps forwarding rate for smooth line-rate performance.

Running Cisco IOS Software, the C1000-24T-4G-L supports VLANs, 802.1Q trunking, QoS, STP/RSTP/MSTP, LACP, IGMP Snooping, and 802.1X authentication, with configuration via CLI, on-box Web UI, SSHv2, and SNMP. Its fanless 1U rack-mount design makes it ideal for silent deployment in open-plan offices, retail floors, and out-of-the-wiring-closet environments. This unit ships as Cisco Refresh — officially remanufactured and certified by Cisco to meet the same performance and reliability standards as a new unit.

Cisco Catalyst C1000-24T-4G-L - Frequently Asked Questions (FAQ)

• Does this switch support PoE?
  No. The C1000-24T-4G-L is a non-PoE data-only switch. For PoE+ at the same port count, choose the C1000-24P-4G-L (195W budget) or C1000-24FP-4G-L (370W budget).
• What is the difference between C1000-24T-4G-L and C1000-24T-4X-L?
  Both are 24-port Gigabit data switches on the same Catalyst 1000 platform. The -4G-L has 4x 1G SFP uplinks; the -4X-L has 4x 10G SFP+ uplinks. All other specs are otherwise identical.
• Does this switch support Layer 3 routing?
  No. The C1000-24T-4G-L is a Layer 2 managed switch and does not support dynamic routing. For Layer 3 features, step up to a Cisco Catalyst 9200 or newer L3-capable platform.
• Which SFP modules are compatible with the 4x 1G uplinks?
  The uplinks support standard Cisco 1G SFP modules, including GLC-SX-MMD (multi-mode), GLC-LH-SMD (single-mode), and compatible 1000BASE-T SFPs (e.g., GLC-T / GLC-TE). SFPs are sold separately.
