WS-C2940-8TF-S is a fanless, managed Layer 2 desktop switch with eight 10/100 copper access ports, an integrated 100BASE-FX fiber interface, and a 1G SFP uplink slot. The access ports provide data connectivity without PoE, so connected endpoints require separate power. The Catalyst 2940 family serves small workgroups outside the wiring closet, including classrooms and conference rooms, where a compact chassis can sit near users. Its fixed uplink architecture does not require a removable network card. The discontinued WS-C2940-8TT-S sibling instead provides a 10/100/1000BASE-T copper uplink, distinguishing the two variants by their upstream connection rather than access-port density.

3.6 Gbps switching capacity establishes the standalone forwarding bandwidth, while 2.7 Mpps forwarding at 64-byte packet sizes defines the packet-processing rating. WS-C2940-8TF-S carries 16 MB of DRAM and 8 MB of flash for its Cisco IOS software and stored configuration. An 8000-entry MAC table bounds address learning. Cisco Catalyst 2940-8TF supports STP, IGMP snooping, VTP, UDLD, and port-based traffic controls for Layer 2 operation; inter-VLAN routing requires a separate routing device. Administrators can use the CLI, web-based configuration tools, and SNMP to configure and monitor the unit. Console access provides a local management connection, while Telnet supplies remote CLI access. Cluster Management Suite centralizes administration without creating a shared hardware forwarding stack.
ORM Systems offers WS-C2940-8TF-S new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, and optics bay recognition, with firmware verified and configuration wiped to factory default. Specify the required condition, quantity, and any separately selected optics on the purchase order. New units include up to a 3-year extended ORM warranty, certified refurbished units up to 1 year, and every condition has 30-day returns; terms apply, while Cisco service has ended. For enterprise and volume orders, POs are accepted, government purchases qualify for Net-30, and RMA service includes advance replacement, with regional stock and RMA coverage across UK, EU, US, and MEA.

When a lab needs to inspect switching behavior before returning hardware to an existing installation, SPAN mirrors selected traffic to an analyzer. Only one SPAN session is available, so competing monitoring requirements cannot receive independent sessions. Specify the source ports, analyzer connection, and required firmware before the purchase order.
When a legacy workgroup needs replacement hardware at an exposed desk or wall position, CABLEGUARD-C2940= secures the unit and Ethernet cable jacks. A standard cable lock can use the side security slot but is not supplied by Cisco. Specify the security accessory and mounting arrangement on the purchase order.
Gigabit speeds on access ports
WS-C2940-8TF-S limits its eight copper access ports to 10/100 Mbps. The 1G SFP uplink does not increase the supported speed of those endpoint connections.
Two simultaneous independent fiber uplinks
WS-C2940-8TF-S permits either the integrated 100BASE-FX interface or the 1G SFP interface to operate, not both. The interfaces do not provide two simultaneous uplink paths.
Active Cisco manufacturer support
Catalyst 2940 is retired and no longer supported by Cisco. WS-C2940-8TF-S therefore does not meet a requirement for an actively supported manufacturer product or current Cisco service.

WS-C2940-8TF-S identifies a managed, standalone Catalyst 2940 switch with eight 10/100 access ports and a 100BASE-FX/SFP uplink arrangement. WS-C2940 identifies the family, 8 identifies the access-port count, and TF identifies the fiber-oriented configuration. Retain the complete -S ending when specifying this exact hardware identifier.
WS-C2940-8TF-S is managed through the Cisco IOS CLI over console or Telnet, web-based Express Setup and Cluster Management Suite, and SNMP. CiscoWorks can also manage the unit. The console supplies local access, while the web tools and remote protocols provide configuration and monitoring through the network.
WS-C2940-8TF-S is retired, and Cisco service has ended for the Catalyst 2940 family. Remaining inventory does not restore Cisco support or return the series to current status. New sealed and certified refurbished describe the condition supplied on the reseller order; neither changes the manufacturer's retirement status.
ORM offers WS-C2940-8TF-S new sealed or certified refurbished, with separate ORM coverage: new units receive up to a 3-year extended warranty, and certified refurbished units up to 1 year. Every condition has 30-day returns; terms apply. Catalyst 2940 originally carried Cisco's limited lifetime warranty, but Cisco service and manufacturer coverage have ended.
WS-C2940-8TF-S supports GLC-SX-MM= for 1000BASE-SX and GLC-LH-SM= for 1000BASE-LX/LH connectivity through its Gigabit SFP slot. Both use LC connectors. The integrated 100BASE-FX interface instead uses MT-RJ multimode fiber, and only one uplink interface can operate at a time.
WS-C2940-8TF-S provides a 100BASE-FX/SFP fiber-uplink arrangement, while WS-C2940-8TT-S provides a 10/100/1000BASE-T copper uplink. Both have eight 10/100 access ports and both are discontinued. The fiber variant matches legacy fiber-connected installations; the copper variant matches installations retaining an RJ-45 upstream connection.
No, WS-C2940-8TF-S does not supply PoE to connected endpoints. Devices attached to its eight 10/100 access ports need a separate power source. Installing a compatible SFP changes the upstream connection, not endpoint powering, so attached phones or other powered devices require their own power arrangements.
No, Catalyst 2940 switches are standalone units rather than hardware-stack members. Cluster Management Suite provides centralized administration, which is different from a shared forwarding stack. Each unit retains its own forwarding capacity and uplink connection; management grouping does not create additional stack bandwidth or a dedicated stack interconnect.
WS-C2940-8TF-S uses an internal AC power supply accepting 100-240V AC and has 15W maximum consumption. The unit connects to an AC outlet through a power cord rather than an external power brick. The cord supplied with an order must match the installation's outlet standard.
Cisco Catalyst 2940-8TF provides 3.6 Gbps switching capacity and 2.7 Mpps forwarding, with the packet rate rated at 64 bytes. These are standalone-unit figures rather than combined cluster throughput. Aggregate switching capacity does not increase the link speed available to an individual Fast Ethernet endpoint port.
