WS-C3750-24PS-E is a managed, stackable Layer 3 access switch with 24 10/100 Mbps PoE ports and two fixed 1G SFP uplinks. The 1U rack-mount chassis belongs to the Cisco Catalyst 3750 Series and supplies IEEE 802.3af or Cisco prestandard power to compatible phones and wireless access points. IP Services is the included software image for advanced routing at the enterprise access edge. The discontinued WS-C3750-24TS-E matches the access-port count and uplink arrangement but does not provide endpoint power. Uplinks use built-in cages rather than a removable network card, so the chassis has no modular path to a faster uplink interface. Evaluate endpoint connection speeds separately from uplink speeds when specifying this legacy configuration.

32 Gbps switching capacity carries traffic through the switching fabric, while 6.5 Mpps forwarding defines packet-processing throughput for this hardware. 370W of PoE budget covers endpoint allocation, with a 15.4W per-port ceiling. OSPF, EIGRP, BGPv4, and IS-ISv4 support dynamic unicast routing; PIM-SM, PIM-DM, and PIM sparse-dense mode handle routed multicast. WS-C3750-24PS-E has 128 MB of DRAM and 16 MB of flash for system operation and image storage. Configurable resource allocation supports 12000 MAC entries and a total of 11000 unicast routes, with the selected resource template determining allocation to the intended configuration. Catalyst 3750 management combines the Cisco IOS CLI, browser-based setup, Cisco Network Assistant, and CiscoWorks integration. LACP aggregates compatible links, while spanning-tree protocols control Layer 2 loops. 462W measured input at full throughput with maximum PoE load informs AC provisioning; this measurement is distinct from the supply rating. Native SFP uplinks do not provide 10G operation.
Specify WS-C3750-24PS-E in new sealed or certified refurbished condition, with the required quantity and accessories on the PO. Certified refurbished units are inspected and bench-tested; PoE output is verified under load on every powered port, firmware is verified, and configurations are wiped to factory default. ORM provides an up to 3-year extended warranty for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition, terms apply; Cisco's original limited lifetime warranty ended July 31, 2015. For enterprise and volume orders, ORM accepts POs, government Net-30, and RMA with advance replacement, with regional stock and RMA in UK, EU, US, and MEA.

When a retained access segment needs inter-VLAN routing on the same hardware, the SVI requirement determines whether the configuration fits. Use 128 SVIs as the recommended sizing point; 1000 are supported depending on route and multicast entries. Specify the intended interface inventory and resource template before the PO.
When a staging environment must reproduce an existing Fast Ethernet configuration, frame size matters as well as connector type. Fast Ethernet bridging and routing are limited to 1546 bytes, so a jumbo-frame requirement needs review before purchase. Specify the test frame sizes and required configuration for the order.
Where multiple retained branch networks need the same voice traffic policy, configuration consistency drives the hardware order. AutoQoS and four egress queues per port provide the configuration elements for reproducing differentiated traffic handling. Include the required QoS policy and staging configuration in the PO rather than relying on factory defaults.
Gigabit Ethernet access connections
Access ports on WS-C3750-24PS-E stop at 100 Mbps. Current C9300L-24P-4G-A retains 24 copper access ports but raises their native speed to 1 Gbps.
PoE+ power for endpoints
WS-C3750-24PS-E supplies IEEE 802.3af power at 15.4W per port, not PoE+. Current C9300L-24P-4G-A provides PoE+ on 24 Gigabit Ethernet access ports.
Active Cisco hardware support
WS-C3750-24PS-E passed its July 31, 2015 last date of support; Cisco service has ended. Current C9300L-24P-4G-A is the successor for replacement procurement.

WS-C3750-24PS-E identifies a Catalyst 3750 with 24 10/100 PoE ports, two Gigabit Ethernet SFP uplinks, and IP Services software. WS-C3750 names the switch family, 24 is the access-port count, PS identifies the PoE/SFP configuration, and E selects the IP Services image.
The Cisco Catalyst 3750 Series supports CLI management through console, Telnet, or SSH, browser setup, Cisco Network Assistant, and CiscoWorks with SNMPv1, SNMPv2c, or SNMPv3. SSH and encrypted SNMPv3 require a cryptographic image. Physical stacks use one management IP address, so verify the image and define management access before commissioning.
WS-C3750-24PS-E includes the IP Services Cisco IOS image, not the IP Base image used by standard variants. IP Services enables advanced unicast routing, multicast routing, and hardware IPv6 routing. For a refurbished order, specify IP Services and verify the software entitlement and installed image before deployment.
WS-C3750-24PS-E provides 370W of PoE with a 15.4W per-port maximum and supports all 24 ports at that level. IEEE 802.3af and Cisco prestandard powered endpoints are supported, but PoE+ is not. Match the endpoint power requirement to the port limit before selecting the order quantity.
WS-C3750-24PS-E has two fixed 1G SFP uplinks, with GLC-SX-MM= for SX connectivity and GLC-LH-SM= for LH connectivity. GLC-SX-MM= and GLC-LH-SM= use LC connectors. Select the optical connection to match the installed fiber and required reach; the switch has no removable uplink card or native 10G uplinks.
StackWise connects nine Catalyst 3750 switches as one logical system over a 32 Gbps interconnect. CAB-STACK-50CM=, CAB-STACK-1M=, and CAB-STACK-3M= provide the available cable lengths. Catalyst 3750-E members can join the same stack, and the master synchronizes the software revision and global configuration across members.
WS-C3750-24PS-E supports OSPF, EIGRP, BGPv4, IS-ISv4, and PBR under its IP Services image. Multicast routing includes PIM-SM, PIM-DM, and PIM sparse-dense mode, while OSPFv6 and EIGRPv6 cover IPv6 routing. The configurable unicast route total reaches 11000, so select the resource profile against the intended routing configuration.
Yes, WS-C3750-24PS-E supports external backup power from PWR-RPS2300 or PWR675-AC-RPS-N1= rather than redundant internal PSU modules. PWR-RPS2300 uses CAB-RPS2300=, while PWR675-AC-RPS-N1= includes one connector cable. The chassis also accepts 100-240V AC through its internal supply; specify the external system and connection equipment separately.
No, WS-C3750-24PS-E passed its July 31, 2015 last date of support, following end of sale on July 5, 2010; Cisco service has ended. Its discontinued WS-C3750V2-24PS-E replacement was followed by discontinued WS-C3650-24PS-E and current C9300L-24P-4G-A. Treat retained deployment and migration procurement as separate purchasing decisions.
WS-C3750-24PS-E supplies PoE, whereas the discontinued WS-C3750-24TS-E does not. Both have 24 10/100 access ports, two 1G SFP uplinks, and IP Services software. The PoE model fits retained powered endpoints; the non-PoE model fits legacy devices with separate power supplies.
WS-C3750-24PS-E includes IP Services, whereas the discontinued WS-C3750-24PS-S includes IP Base. IP Services adds advanced unicast and multicast routing; IP Base provides static routing, RIP, and EIGRP stub routing. The E model fits legacy routed-access requirements; the S model fits configurations needing only the base feature set.
C9300L-24P-4G-A provides 1G copper access where WS-C3750-24PS-E provides 10/100 Mbps access. The current successor is reached through the discontinued WS-C3750V2-24PS-E and WS-C3650-24PS-E replacements. The original model fits retained Fast Ethernet environments; C9300L-24P-4G-A suits buyers moving those access connections to Gigabit Ethernet.
ORM offers WS-C3750-24PS-E new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Every condition has 30-day returns, terms apply. Cisco's original limited lifetime warranty ended with support on July 31, 2015. Refurbished units are inspected and bench-tested, with firmware verified and configuration wiped to factory default.
