WS-C3750E-24PD-S combines 24 Gigabit Ethernet PoE access ports with two fixed X2-based 10G uplink positions in a 1U enterprise access switch. The Catalyst 3750-E model ships with IP Base software and supports Layer 3 operation within that feature set, rather than the advanced routing functions associated with IP Services. Copper connections serve PCs alongside IP phones and wireless access points, while the uplink positions connect toward aggregation. Unlike the powered model, the discontinued WS-C3750E-24TD-S provides data-only access ports. Voice VLAN support keeps telephony traffic on a separate VLAN for administration and troubleshooting, allowing the access configuration to distinguish phone traffic from other endpoint traffic.

160 Gbps switching capacity supports switching between the access and uplink interfaces. 65.5 Mpps forwarding provides the packet-rate reference for traffic sizing. 420W of shared PoE output requires aggregate endpoint allocations to remain within the available power budget. Static routing, RIPv1, RIPv2, RIPng, and EIGRP Stub support the included feature set's routed-edge functions; OSPF and BGPv4 require IP Services. WS-C3750E-24PD-S carries 256 MB DRAM and 64 MB flash for runtime operation and local software-image storage. Cisco Catalyst 3750E-24PD hardware also supports 9216-byte jumbo frames, so connected devices need a consistent frame-size configuration. MAC and route maxima depend on the selected SDM template and should not be treated as simultaneously available resources. 509W measured draw at full throughput with the maximum tested PoE load provides a loaded operating reference, rather than a substitute for electrical capacity planning.
Specify WS-C3750E-24PD-S in new sealed or certified refurbished condition, with required accessories itemized on the purchase order. Certified refurbished units are inspected and bench-tested, including PoE output under load on every powered port, with firmware verified and configuration wiped to factory default. ORM provides up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units, plus 30-day returns on every condition, terms apply; Cisco's original 90-day limited hardware and software warranty and service ended January 31, 2018. Enterprise and volume orders receive PO acceptance, Net-30 for government, and RMA with advance replacement through UK, EU, US, and MEA stock and RMA regions.

When a maintenance team is replacing an existing rack-mounted unit, the purchase order needs the mounting hardware as well as the chassis. RCKMNT-E-1RU= is the rack-mount kit for this family. Confirm the bracket requirement and installed accessory inventory before ordering a replacement for the existing rack position.
When a lab must reproduce an existing configuration, the selected SDM template matters as much as the hardware identity. The default template provides 6000 MAC addresses and 8000 total unicast routes. Preserve the intended template and validate the configuration during staging before specifying the production order.
When several sites use an IP phone and a PC on the same desk connection, Multi-Domain Authentication separates the devices into voice and data VLANs on one physical port. Include the intended authentication policy and VLAN assignments in the staging requirements before approving a standardized purchase order.
30W PoE+ endpoint power
Cisco Enhanced PoE stops at 20W per port rather than providing 30W PoE+. C9300-24P-A is the current 24-port PoE+ replacement reached through the lifecycle chain.
Active Cisco hardware support
Cisco service for this model ended January 31, 2018. C9300-24P-A is the current replacement-chain endpoint; intermediate WS-C3750X-24P-S and WS-C3850-24P-S are discontinued.
Dual internal power supplies
Only one internal power-supply slot is available, and external PWR2300-AC-RPS-N1= provides backup power. A second internal power supply cannot be installed in this chassis.

WS-C3750E-24PD-S identifies a Catalyst 3750-E switch with 24 Gigabit PoE ports, two X2-based 10G uplinks, and IP Base software. WS-C3750E names the family, 24 gives the access-port count, PD identifies this powered-port configuration with its uplinks, and S selects IP Base rather than IP Services.
Catalyst 3750-E switches support Cisco IOS CLI access through the console, Telnet, or SSH, plus Cisco Network Assistant, CiscoWorks LMS, and SNMP management. SSH and encrypted SNMPv3 require a cryptographic software image. An out-of-band Ethernet management port separates administrative connectivity from the access ports.
WS-C3750E-24PD-S is discontinued: end of sale was January 30, 2013, and Cisco service ended January 31, 2018. WS-C3750X-24P-S was the immediate replacement but is also discontinued. The chain continues through discontinued WS-C3850-24P-S to current C9300-24P-A, rather than ending at either intermediate model.
ORM offers WS-C3750E-24PD-S new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year. Every condition includes 30-day returns, terms apply. Cisco's original 90-day limited hardware and software warranty is no longer active; Cisco service ended January 31, 2018.
WS-C3750E-24PD-S includes IP Base and uses Cisco IOS Software Activation with a local license file; IP Services is the upgrade tier. The 24-port upgrade identifier is 3750E-IPSLCB-QTY. Used-equipment relicensing uses LL-3750E-IPB= or LL-3750E-IPS=, so hardware condition and software entitlement need separate confirmation.
WS-C3750E-24PD-S provides a shared 420W PoE budget, with standard 15.4W delivery and Cisco Enhanced PoE reaching 20W per port. The aggregate allowance, not the per-port ceiling, governs how many high-draw devices may be powered together. Confirm each endpoint's requested power before defining the powered-port allocation.
Catalyst 3750-E switches provide two X2-based 10G uplink positions; compatible choices include X2-10GB-SR= and X2-10GB-LR=. CVR-X2-SFP= converts one X2 position into two Gigabit SFP interfaces. Specify the required optics or converters by part number, because the selected components determine the physical connection type and speed.
Nine switches form a Catalyst 3750-E StackWise Plus stack, with 64 Gbps stacking bandwidth and backward compatibility with Catalyst 3750 members. Cable choices include CAB-STACK-50CM=, CAB-STACK-1M=, and CAB-STACK-3M=. Check the installed members and physical spacing before specifying additional interconnects for the purchase order.
No, WS-C3750E-24PD-S ships with C3K-PWR-750WAC and has only one internal power-supply slot. External backup uses PWR2300-AC-RPS-N1= rather than a second internal supply. Measured consumption reaches 509W at full traffic with the maximum tested PoE load; the 750W rating of C3K-PWR-750WAC is not actual operating draw.
WS-C3750E-24PD-S supplies PoE on its access ports, while WS-C3750E-24TD-S is data-only. Both identifiers belong to the discontinued Catalyst 3750-E family. The powered model matches legacy phone or access-point connections needing switch-delivered power; the data-only model matches existing installations where endpoints receive their operating power separately.
WS-C3750E-24PD-S ships with IP Base, whereas WS-C3750E-24PD-E ships with IP Services. The latter enables OSPF, BGPv4, and full EIGRP that the base tier does not provide. Both models are discontinued: the S model matches base-tier replacement needs, and the E model matches legacy advanced-routing configurations.
WS-C3750E-24PD-S reached its last Cisco support date on January 31, 2018, while C9300-24P-A is the current endpoint of its replacement chain. The discontinued unit addresses like-for-like legacy hardware requirements; the current model is the migration target for buyers replacing the older product line rather than maintaining it.
