WS-C3750-24PS-S is a managed Layer 3 access switch with 24 10/100 Mbps RJ-45 ports and two fixed 1G SFP uplinks. IEEE 802.3af PoE powers compatible phones and wireless access points over the access cabling. The Cisco Catalyst 3750 Series combines this Fast Ethernet configuration with IP Base software in a 1U rack-mount chassis for enterprise access networks. Dedicated stack ports connect members without consuming access or uplink interfaces. The discontinued WS-C3750-24TS-S is the nearest non-PoE sibling for legacy installations with separately powered endpoints. This model serves buyers maintaining an existing hardware standard; Gigabit access and PoE+ are not part of its native configuration.

32 Gbps switching capacity carries traffic through the switching fabric, while 6.5 Mpps forwarding handles packet processing for this configuration. 370W of PoE capacity covers the aggregate endpoint load. Static routing, RIPv1, RIPv2, and EIGRP Stub support routed access under IP Base. OSPF, BGPv4, IS-ISv4, and PIM-SM require IP Services and are not included in the shipped image. WS-C3750-24PS-S carries 128 MB of DRAM and 16 MB of flash for its operating image and configuration. The 12000-entry MAC capacity and 11000-route IPv4 hardware capacity define different forwarding resources, not interchangeable limits. LACP supports aggregated links, while RSTP handles spanning-tree convergence. Catalyst 3750 administrative access includes local console and remote management tools, with SSH dependent on a cryptographic software image. 495W maximum consumption sets the upper facility power allowance rather than the measured unloaded operating draw.
ORM Systems offers WS-C3750-24PS-S in new sealed and certified refurbished condition; new orders include up to a 3-year extended warranty, certified refurbished orders include up to 1 year, and every condition has 30-day returns, with terms applying. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed links on every port, PoE output under load on every powered port, and optics bay recognition; firmware is verified and configurations are wiped to factory default. Specify condition, quantity, and required accessories on the purchase order before release. Enterprise and volume orders can use PO purchasing and Net-30 for government; Cisco's original limited lifetime coverage ended on July 31, 2015.

When a replacement order must retain existing powered phones or access points, endpoint nameplate demand matters before hardware quantity. A powered access port delivers 15.4W maximum, which rules out assuming higher-draw devices will receive their required power. Specify endpoint power requirements before the PO.
When an existing switch stack needs another member, cable reach and software alignment belong on the replacement order. CAB-STACK-1M= and CAB-STACK-3M= provide different installation spans, while the stack master synchronizes the software revision and global configuration. Specify the cable PID and existing software revision before the PO.
When a routed access replacement must preserve an existing VLAN design, interface scale deserves a separate configuration review. The Catalyst 3750 recommends 128 switch virtual interfaces, rather than treating hardware route capacity as a VLAN-interface guarantee. Specify the SVI plan and required routing features before the PO.
Gigabit Ethernet access for endpoints
WS-C3750-24PS-S access ports stop at 100 Mbps. C9300L-24P-4G-A provides 24 Gigabit-capable PoE+ access ports and four fixed 1G uplinks for a current hardware migration.
PoE+ power for higher-draw endpoints
WS-C3750-24PS-S supplies 15.4W maximum per powered port, not PoE+. C9300L-24P-4G-A supports PoE+ while retaining 24 access ports and increasing the fixed uplink count to four.
10G uplinks to distribution switches
WS-C3750-24PS-S has fixed 1G SFP uplinks without a removable network-module bay. Its uplink interfaces cannot be upgraded to 10G by installing different optics.

WS-C3750-24PS-S identifies a Catalyst 3750 with 24 Fast Ethernet PoE ports, two SFP uplinks, and IP Base software. WS-C3750 identifies the family, 24 the access-port count, P PoE, S the SFP uplinks, and the final -S the IP Base image.
The Catalyst 3750 is managed through a web device manager, Cisco Network Assistant, the Cisco IOS CLI over console or Telnet, CiscoView, CiscoWorks, and SNMP. SSH requires a cryptographic software image. These methods provide local configuration, remote administration, and integration with compatible network-management applications.
Yes, WS-C3750-24PS-S reached end of sale on July 5, 2010, and its last date of support was July 31, 2015. Cisco service has ended. Software maintenance ended July 4, 2013, so a purchase maintains legacy hardware rather than restoring manufacturer support or ongoing software maintenance.
ORM offers WS-C3750-24PS-S new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Returns cover 30 days on every condition; terms apply. Cisco's original limited lifetime hardware warranty ended with support on July 31, 2015.
WS-C3750-24PS-S ships with the Cisco IOS IP Base image, while the Catalyst 3750 family also offers IP Services. IP Base includes basic unicast routing and EIGRP Stub; IP Services adds advanced routing features. The software image determines feature availability independently of the physical port configuration.
WS-C3750-24PS-S has a 370W PoE budget and supplies a maximum of 15.4W per powered port. Its 24 access ports power IEEE 802.3af devices within that aggregate allocation. PoE+ is not supported, so higher endpoint power requirements need different hardware rather than a software-image change.
WS-C3750-24PS-S provides two fixed 1G SFP uplink slots, not 10G SFP+ interfaces. Optical choices include GLC-SX-MM= and GLC-LH-SM=; the transceiver must match the intended fiber connection. The uplink slots are built into the chassis and do not accept a removable network card to increase uplink speed.
StackWise supports nine WS-C3750-24PS-S members over a 32 Gbps stack interconnect. Approved cables are CAB-STACK-50CM=, CAB-STACK-1M=, and CAB-STACK-3M=. The stack operates as one logical switch; dedicated stack ports carry the interconnection without using the front-panel access ports or SFP uplinks.
No, WS-C3750-24PS-S cannot run OSPF with its IP Base image. Static routing, RIPv1, RIPv2, and EIGRP Stub are included. OSPF requires IP Services, as do BGPv4, IS-ISv4, and PIM-SM. The 11000-route IPv4 hardware capacity does not unlock protocols excluded by the installed software image.
No, WS-C3750-24PS-S does not provide two internal power-supply bays. The internal AC supply can receive external backup through PWR-RPS2300 or PWR675-AC-RPS-N1=. PWR-RPS2300 uses CAB-RPS2300= for the switch connection. External backup power is distinct from a second installed internal PSU and requires separate equipment.
WS-C3750-24PS-S is a 1U rack-mount switch with a 445 mm chassis width. Its dimensions are 44 mm high by 445 mm wide by 300 mm deep, and its weight is 5.1 kg. The full-width chassis occupies standard rack space rather than using a compact desktop enclosure.
WS-C3750-24PS-S supplies PoE on its access ports, while WS-C3750-24TS-S does not. Both models are discontinued. The powered version fits replacement orders serving powered endpoints; the non-PoE version fits legacy devices with separate power. Neither choice restores manufacturer support for a retired installation.
WS-C3750-24PS-S ships with IP Base, while WS-C3750-24PS-E ships with IP Services. Both models are discontinued. IP Base includes basic routing and EIGRP Stub; IP Services adds advanced routing. IP Base suits legacy edges with basic routing requirements; IP Services suits existing deployments requiring advanced routing features.
C9300L-24P-4G-A provides four fixed 1G uplinks where WS-C3750-24PS-S has two. The replacement chain passes through discontinued WS-C3750V2-24PS-S and WS-C3650-24PS-S. The older model fits like-for-like maintenance of an existing installation; C9300L-24P-4G-A suits a current hardware migration requiring more fixed uplink interfaces.
