WS-C3750G-24TS-S is a managed, Layer 3 stackable multilayer switch with 24 copper 10/100/1000 access ports and four fixed Gigabit SFP uplinks. Its non-PoE configuration connects endpoints powered separately, while the IP Base image supplies the network software tier. The rack-mount chassis belongs to the Catalyst 3750 Series, which serves access and aggregation requirements in midsized organizations and enterprise branches. Dedicated stacking connections preserve the front-panel interfaces for network traffic rather than consuming an Ethernet uplink. The discontinued WS-C3750G-24PS-S differs by supplying PoE through its copper access ports. The original configuration combines copper endpoint connectivity with fixed fiber uplinks; it does not contain a removable uplink-card bay.

32 Gbps switching capacity provides the switching fabric bandwidth, while 38.7 Mpps forwarding handles 64-byte packets at the published packet-processing rate. Static routing, RIP and EIGRP Stub support routed access; HSRP provides gateway redundancy. WS-C3750G-24TS-S carries 128 MB DRAM for runtime operation and 16 MB flash for image storage. Forwarding resources accommodate 12000 MAC entries and a total of 11000 unicast routes, with SDM templates allocating resources to access, routing or VLAN requirements. STP, RSTP and MSTP manage loop prevention, while LACP supports aggregated Ethernet connections. Configuration is available through the Cisco IOS CLI, Cisco Network Assistant and CiscoWorks, with a browser setup utility for initial addressing and passwords. SSH and encrypted SNMPv3 require a cryptographic software image. 190W maximum power consumption provides the facility planning allowance. The internal AC supply powers the chassis; external backup uses PWR-RPS2300 or PWR675-AC-RPS-N1= rather than a second internal supply bay.
ORM Systems offers WS-C3750G-24TS-S new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units; returns are 30 days on every condition, and terms apply.

When an existing Catalyst 3750 stack needs another member, the purchase includes a physical interconnect decision rather than Ethernet uplink capacity. CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M= provide different cable lengths. Stack members must use the same Cisco IOS version. Specify the cable PID and confirm software alignment before releasing the PO.
When a lab must reproduce large-frame behavior on Gigabit interfaces, the switch supports a 9000-byte MTU and a maximum Ethernet frame size of 9018 bytes for bridging. Those limits concern frame handling, not uplink speed. Specify the required frame size and staging configuration before ordering the lab units.
When branch orders must reproduce an existing voice configuration, the Catalyst 3750 provides four egress queues per port and voice VLAN support. Queue policy therefore belongs in the acceptance criteria, while the voice VLAN separates voice traffic for administration. Specify the required queue behavior and voice VLAN configuration in the staging requirements before the PO.
PoE-powered phones or access points
WS-C3750G-24TS-S does not supply PoE through its access ports. Phones and access points requiring Ethernet-delivered power need a separate power source rather than relying on this switch.
10G uplinks to distribution
The four fixed SFP uplinks operate at Gigabit speed. WS-C3750G-24TS-S has no removable uplink-card bay, so an uplink module cannot add 10G connectivity to this chassis.
Full OSPF or BGP routing
The supplied IP Base image excludes OSPF and BGPv4. Those protocols require IP Services; a factory IP Base order does not include the advanced routing software image.
Active Cisco hardware service
Cisco service for WS-C3750G-24TS-S ended March 15, 2014. C9300-24T-A is the current 24-port data-only migration destination at the end of its replacement chain.

WS-C3750G-24TS-S identifies a Catalyst 3750 Gigabit Ethernet switch with 24 copper ports, four SFP uplinks and IP Base software. WS-C3750G identifies the Gigabit model group; 24TS identifies that copper-and-SFP configuration; the final S identifies IP Base. This exact part uses the original 1.5RU chassis rather than the later 1U version.
The Catalyst 3750 is managed through the Cisco IOS CLI over console, Telnet or SSH, browser setup, Cisco Network Assistant and CiscoWorks. SNMPv1, SNMPv2c and SNMPv3 support network management. SSH and encrypted SNMPv3 require a cryptographic software image, so confirm the installed image when specifying secure remote administration.
Yes, WS-C3750G-24TS-S reached end of sale on March 16, 2009, and its last date of support was March 15, 2014. Cisco service has ended. These dates belong to the original 1.5RU model; the later WS-C3750G-24TS-S1U is a different, also-discontinued part with separate lifecycle milestones.
WS-C3750G-24TS-S comes with the IP Base software image. IP Services is the advanced image option, with CD-3750G-EMI= providing the upgrade kit for this hardware. Specify the required image and entitlement separately when ordering an upgraded unit; the standard S-suffix hardware order identifies IP Base rather than IP Services.
WS-C3750G-24TS-S is offered new sealed or certified refurbished, with ORM warranties of up to 3 years extended for new units and up to 1 year refurbished. Returns are 30 days for every condition; terms apply. Cisco’s original limited lifetime hardware warranty and service ended March 15, 2014. ORM refurbishment is separate from Cisco remanufacturing.
No, WS-C3750G-24TS-S does not provide PoE on its 24 copper access ports. Attached phones, access points and other endpoints must receive power separately. The TS configuration supplies Ethernet connectivity only, so the purchase order should not assign an endpoint power budget to this switch.
WS-C3750G-24TS-S has four fixed Gigabit SFP uplinks, not 10G SFP+ uplinks. GLC-SX-MM= and GLC-LH-SM= are compatible optical choices for the SFP connections. Select the optic and cabling for the existing fiber connection; this chassis does not accept a removable uplink card to change its uplink speed.
A Catalyst 3750 StackWise stack contains a maximum of nine members and uses a 32 Gbps interconnect. Dedicated stack connections do not consume access ports. Cable choices include CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M=. Specify the required cable lengths and align the Cisco IOS versions when adding members to an existing stack.
WS-C3750G-24TS-S supports a configurable total of 11000 unicast routes. That hardware capacity does not add protocols excluded by the software image: IP Base provides static routing, RIP and EIGRP Stub. SDM templates allocate resources to the deployment, so confirm the selected template when reproducing an existing routed configuration.
WS-C3750G-24TS-S uses the RCKMNT-3550-1.5RU= rack-mount kit for its original 1.5RU chassis. The enclosure measures 66 mm high, 445 mm wide and 295 mm deep. Identify this exact hardware revision when specifying mounting accessories; the similarly named 1U replacement is a different chassis rather than the same enclosure.
Yes, WS-C3750G-24TS-S supports external backup power through PWR-RPS2300 or PWR675-AC-RPS-N1=, but not a second internal PSU. The internal supply accepts 100-240V AC. External backup connects through the rear RPS receptacle, so a redundant-power purchase requires the external system rather than an additional internal supply module.
WS-C3750G-24PS-S supplies PoE through its 24 copper access ports, whereas WS-C3750G-24TS-S does not supply endpoint power. Both configurations have four Gigabit SFP uplinks and IP Base software. Both are discontinued. The TS model suits legacy estates with separately powered endpoints; the PS model matches legacy PoE replacement requirements.
WS-C3750G-24TS-E includes IP Services, while WS-C3750G-24TS-S includes IP Base. IP Services adds advanced unicast and multicast routing beyond the base image. Both original 1.5RU models are discontinued. The S model matches legacy base-routing configurations; the E model matches legacy installations requiring the advanced software image on the same port configuration.
C9300-24T-A is the current 24-port data-only migration destination, while WS-C3750G-24TS-S reached its last date of support on March 15, 2014. The direct replacement WS-C3750G-24TS-S1U is also discontinued. Retain the original part for an exact legacy hardware requirement; specify C9300-24T-A when purchasing a current-generation replacement instead.
