WS-C3750G-24PS-S is a managed Layer 3 access switch with 24 Gigabit Ethernet copper ports, IEEE 802.3af PoE, and four fixed Gigabit SFP uplinks. The 1U chassis belongs to the Catalyst 3750G family and ships with IP Base software for enterprise access and branch networks. Copper connections serve workstations, IP phones, and compatible wireless access points, while the separate fiber interfaces connect upstream equipment. The discontinued WS-C3750G-24TS-S1U retains the same access-port density and uplink arrangement but does not supply endpoint power. This 24-port Gigabit PoE switch has built-in stacking connections rather than an uplink-card bay; its fixed uplinks do not provide a removable-card path to faster interfaces.

32 Gbps switching capacity carries traffic through the switching fabric, while 38.7 Mpps forwarding provides the packet-processing figure for this model. 370W of PoE output supplies the powered endpoints; facility sizing must separately account for switch consumption. Static routing, RIPv1, RIPv2, EIGRP Stub, HSRP, and PIM Stub provide IP Base routing functions, but full OSPF and EIGRP routing require IP Services. WS-C3750G-24PS-S has 128 MB DRAM and 32 MB flash for runtime operation and image storage. Configurable scale reaches 12000 MAC addresses and 11000 unicast routes, with resource allocation dependent on the selected switching template. LACP provides link aggregation, and automatic QoS classifies traffic and configures egress queues. Browser-based setup and the Cisco IOS command-line interface offer different configuration paths. 492W measured consumption at full throughput with maximum PoE loading gives a powered-operation figure for electrical planning, rather than treating endpoint output alone as total draw.
Order WS-C3750G-24PS-S in new sealed or certified refurbished condition, specifying quantities, the required regional power cord, and the accessories to include on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, PoE output under load on every powered port, and optics bay recognition; firmware is verified and configurations are wiped to factory default. New units carry up to a 3-year extended warranty, certified refurbished units carry up to 1 year, and returns are available for 30 days on every condition; terms apply. PO orders are accepted, Net-30 is available for government, and RMA includes advance replacement, with regional stock and RMA coverage across the UK, EU, US, and MEA; specify volume quantities together.

An endpoint refresh that retains IEEE 802.3af phones or access points needs a per-device power check rather than a port-count assumption. Powered devices must stay within the 15.4W per-port limit. Specify each endpoint's power requirement and distinguish standard PoE from higher-power requirements before the purchase order.
An existing Catalyst 3750 installation needs another member without changing its stacking architecture. Mixed stacks can include Catalyst 3750-E switches, and members must run a common software version. Specify CAB-STACK-50CM=, CAB-STACK-1M=, or CAB-STACK-3M= according to the physical layout, and check image compatibility before ordering.
A lab reproducing an installed access network needs to exercise security policies before equipment is released for use. The switch supports 1000 access control entries, so rule quantity is a staging constraint rather than an unlimited resource. Check the intended policy set and specify the required software image before the purchase order.
PoE+ or higher endpoint power
WS-C3750G-24PS-S supplies standard PoE at 15.4W per port, not PoE+. C9300-24P-A offers PoE+ with the same 24-port access density.
10G uplinks on this chassis
WS-C3750G-24PS-S has fixed Gigabit SFP uplinks and no removable uplink-card bay. A requirement for native 10G upstream connections exceeds this chassis's uplink capability.
Active Cisco hardware support
WS-C3750G-24PS-S reached its last date of support on January 31, 2018. C9300-24P-A is the current endpoint of its forward migration chain.

WS-C3750G-24PS-S identifies a Catalyst 3750 Gigabit switch: WS-C3750G names the Gigabit model family, 24 identifies the copper-port count, PS identifies powered copper ports with SFP uplinks, and the final S identifies IP Base. The complete configuration includes four Gigabit SFP uplinks and standard PoE rather than PoE+.
WS-C3750G-24PS-S is managed through a browser-based device manager, Cisco Network Assistant, Cisco IOS CLI over the console or Telnet, and SNMP applications including CiscoWorks and CiscoView. SSH requires a cryptographic software image. Select the intended management image and access method before staging the unit.
WS-C3750G-24PS-S ended sale on January 30, 2013, and reached its last date of support on January 31, 2018. Software maintenance ended January 30, 2014, and vulnerability support ended January 30, 2016. The switch is discontinued and no longer has active Cisco hardware support.
ORM offers WS-C3750G-24PS-S new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are 30 days on every condition; terms apply. Cisco's original Limited Lifetime Warranty is no longer active: Cisco service ended January 31, 2018.
IP Base is the installed software tier on WS-C3750G-24PS-S, and CD-3750G-EMI= provides the IP Services image upgrade. IP Services adds advanced routing functions beyond the base image. Specify the required entitlement with the order; changing the image does not change the physical port configuration.
WS-C3750G-24PS-S provides a 370W PoE budget and supports 15.4W on each of its 24 powered ports simultaneously. The ports support IEEE 802.3af and Cisco prestandard PoE, not PoE+. Check endpoint power requirements separately from the switch's total electrical consumption when preparing the equipment list.
Catalyst 3750 StackWise stacks nine members with a 32 Gbps interconnect through dedicated rear stacking ports. Approved cable options are CAB-STACK-50CM=, CAB-STACK-1M=, and CAB-STACK-3M=. Choose cable lengths for the installed layout and confirm a common software version across members before adding another switch to the stack.
The 24-port Gigabit PoE switch provides four fixed Gigabit SFP uplinks, not SFP+ uplinks or a removable uplink-card bay. Optical options include GLC-SX-MM= and GLC-LH-SM=. Match the transceiver to the fiber installation and remote interface rather than assuming that every SFP has the same optical characteristics.
No, WS-C3750G-24PS-S does not have a second internal power-supply bay; power redundancy uses an external system. Compatible options are PWR-RPS2300 and PWR675-AC-RPS-N1=. The internal supply accepts 100-240V AC. Specify the external redundancy equipment separately if the purchase requires protection against an internal supply failure.
WS-C3750G-24PS-S supplies PoE on its copper access ports, while WS-C3750G-24TS-S1U is non-PoE. Both retain 24 Gigabit copper connections and four Gigabit SFP uplinks. Both models are discontinued; the powered model matches installations supplying endpoint power, while the non-PoE model matches installations with independently powered endpoints.
WS-C3750G-24PS-S ships with IP Base, while WS-C3750G-24PS-E ships with IP Services. IP Services includes full OSPF and EIGRP routing beyond the base image's routing functions. Both models are discontinued; IP Base suits matching existing base-image installations, while IP Services suits installations requiring the advanced routing image.
C9300-24P-A is the current migration endpoint for WS-C3750G-24PS-S, which is discontinued and beyond Cisco support. WS-C3750X-24P-S and WS-C3850-24P-S are discontinued intermediate replacements. The older switch serves installed-base matching and sparing requirements; C9300-24P-A serves a purchase intended to move away from the retired hardware lifecycle.
