WS-C3750-24TS-S is a managed Layer 3 access switch with 24 10/100 Mbps copper ports, two fixed 1G SFP uplinks and the IP Base software image. Its non-PoE hardware connects separately powered endpoints in a rack-mount 1U chassis. The Cisco Catalyst 3750 Series serves enterprise access and branch networks with QoS classification, rate limiting and access controls at the edge. Voice VLAN support separates telephony traffic from other data, while port security restricts connected devices by MAC address. The discontinued WS-C3750-24PS-S is the nearest powered sibling when comparing legacy configurations. Buyers retaining this generation should distinguish the required endpoint speed, power arrangement and software image rather than treating all 24-port configurations as equivalent.

32 Gbps switching capacity provides the fabric for forwarding access traffic toward aggregation. 6.5 Mpps forwarding supports packet-rate planning for 64-byte traffic on the standalone switch. Static, RIP and EIGRP Stub routing support inter-VLAN connectivity and limited routed access; advanced hardware-based IPv6 routing is outside the supplied image. WS-C3750-24TS-S carries 128 MB DRAM for software operation and 16 MB flash for image storage. The Catalyst 3750 can be configured for 12000 MAC entries and a total of 11000 unicast routes, with Switching Database Manager templates directing resource allocation toward access, routing or VLAN use. RSTP and Cross-Stack EtherChannel support loop control and link aggregation. 45W consumption at 100% throughput provides a traffic-loaded reference for electrical planning. DHCP Snooping and Dynamic ARP Inspection enforce address-related controls, while RSPAN and the embedded RMON agent support traffic observation. IGMP snooping limits multicast delivery to requesting ports.
WS-C3750-24TS-S is offered new sealed with ORM's up to 3-year extended warranty or certified refurbished with up to 1 year; Cisco service and the original hardware warranty ended July 31, 2015. Certified refurbished units are inspected and bench-tested for power-on, POST, rated-speed port links, optics bay recognition and clean boot. Specify the condition, quantity and RCKMNT-1RU= mounting kit requirements before submitting the PO; every condition includes 30-day returns, with terms applying. Enterprise and volume orders support PO acceptance, Net-30 for government and RMA with advance replacement across UK, EU, US and MEA stock/RMA regions.

An existing Catalyst 3750 stack needing another member can combine Catalyst 3750 and discontinued Catalyst 3750-E switches within the same logical unit. The stack master loads its Cisco IOS revision and global configuration onto added members. Record the installed member models and software image, then verify the intended stack combination before the PO.
A staging environment that needs repeatable VLAN and spanning-tree configurations can use the switch's limits of 1005 VLANs per switch or stack and 128 spanning-tree instances per switch. These are separate limits, not interchangeable counts. Specify the planned VLAN inventory and spanning-tree instance requirements before ordering units for the lab.
A spare-stock purchase for managed switches needs an acceptance scope rather than a condition label alone. Certified refurbished units have firmware verified and their configuration wiped to factory default. For WS-C3750-24TS-S, specify that managed-unit preparation and the required condition on the PO so replacement inventory arrives without the previous configuration.
Gigabit copper endpoint connections
WS-C3750-24TS-S limits its copper access ports to 10/100 Mbps. C9300L-24T-4G-A provides 24 Gigabit copper access ports for buyers replacing that access-speed ceiling.
PoE-powered phones or access points
WS-C3750-24TS-S supplies data connectivity without PoE output. Phones or access points that rely on switch-delivered power cannot receive that power from these access ports.
10G uplinks from this chassis
WS-C3750-24TS-S has fixed 1G SFP uplinks and no uplink-card bay. A 10G distribution connection cannot be added by fitting a faster transceiver to this chassis.

The WS-C3750-24TS-S part number identifies a Catalyst 3750 switch: WS-C3750 names the family, 24 gives the access-port count, TS corresponds to 10/100 Ethernet access with two Gigabit SFP uplinks, and the final S selects IP Base. This is the non-PoE configuration.
WS-C3750-24TS-S is managed through the Cisco IOS CLI over console, Telnet or SSH, browser-based setup, Cisco Network Assistant and CiscoWorks with SNMPv1, SNMPv2c or SNMPv3. SSH and cryptographic SNMPv3 require a cryptographic software image; remote management must be configured before use.
No, WS-C3750-24TS-S does not supply PoE through its 24 copper access ports. Endpoint devices must use their own power sources rather than draw power from the switch. The IP Base software tier and the SFP uplinks do not add power-delivery capability to this hardware.
Two fixed 1G SFP ports provide the uplinks on WS-C3750-24TS-S; the chassis has no uplink-card bay or 10G uplinks. GLC-SX-MM= and GLC-LH-SM= are compatible fiber transceiver options. Specify the fiber medium and far-end connection when choosing optics, because a transceiver changes the medium rather than the uplink speed class.
Nine switches form one Catalyst 3750 StackWise stack, connected over a 32 Gbps stacking bus. CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M= provide the cable options. Stacks are managed as one logical switching unit with one IP address, so specify cable reach and the intended member layout before ordering.
IP Base on WS-C3750-24TS-S supports Static, RIP and EIGRP Stub routing, including inter-VLAN routing. The hardware can be configured for a total of 11000 unicast routes, but that figure does not enable additional protocols. OSPF, BGPv4, full EIGRP and PBR require IP Services rather than the as-shipped image.
IP Base is the included software image for WS-C3750-24TS-S, and CD-3750-EMI= is the matching IP Services image upgrade kit. IP Services adds advanced unicast, multicast and IPv6 routing. Specify the required image and confirm software entitlement and upgrade availability when ordering a refurbished unit or planning an image change.
Yes, WS-C3750-24TS-S is a rack-mount 1U switch measuring 44 mm high, 445 mm wide and 300 mm deep. RCKMNT-1RU= is the compatible mounting kit. Include the required RCKMNT-1RU= hardware on the PO rather than assuming mounting accessories accompany every condition.
WS-C3750-24TS-S accepts 100-240V AC through its internal supply, with optional DC backup from PWR-RPS2300 or PWR675-AC-RPS-N1=. PWR-RPS2300 or PWR675-AC-RPS-N1= detects an internal supply failure and powers the connected switch automatically. Specify the chosen backup PID on the PO when ordering power redundancy.
WS-C3750-24TS-S is discontinued: Cisco sales ended July 5, 2010, and hardware support ended July 31, 2015. The immediate replacement, WS-C3750V2-24TS-S, is also discontinued; the forward replacement chain reaches C9300L-24T-4G-A. Purchases now depend on reseller inventory and reseller support rather than active Cisco hardware service.
WS-C3750-24PS-S supplies PoE on 24 access ports, whereas WS-C3750-24TS-S provides data-only access. Both older models are discontinued. WS-C3750-24TS-S suits legacy networks with separately powered endpoints; WS-C3750-24PS-S suits legacy PoE endpoints within its shared 370W budget, which must be sized against the connected powered devices.
WS-C3750-24TS-E includes IP Services, while WS-C3750-24TS-S includes IP Base; both models are discontinued. IP Services enables OSPF, BGPv4 and full EIGRP, beyond IP Base's EIGRP Stub capability. The standard model suits legacy basic routed access, while the enhanced model suits legacy configurations requiring those advanced routing protocols.
C9300L-24T-4G-A has four fixed 1G SFP uplinks, compared with two on the discontinued WS-C3750-24TS-S. C9300L-24T-4G-A is the current endpoint of the forward replacement chain. WS-C3750-24TS-S suits retention of a legacy two-uplink layout, while C9300L-24T-4G-A suits a refresh requiring four individual 1G uplink connections.
ORM Systems offers WS-C3750-24TS-S new sealed with up to a 3-year extended warranty or certified refurbished with up to a 1-year warranty. Both conditions include 30-day returns; terms apply. Cisco's original limited lifetime hardware warranty ended with Cisco service on July 31, 2015. Refurbished units are inspected and bench-tested.
