WS-C3750-48PS-E is a Layer 3 enterprise access switch with 48 Fast Ethernet RJ-45 ports, IEEE 802.3af PoE and four fixed Gigabit SFP uplinks. The rack-mount 1U chassis belongs to the Catalyst 3750 family and includes the IP Services software image for advanced routed access and multicast configurations. Copper endpoint connections operate at 10/100 Mbps, while the separate uplink cages provide Gigabit connections toward distribution equipment. This 48-port Fast Ethernet PoE switch powers compatible Cisco IP phones, wireless access points and other IEEE 802.3af endpoints within a shared allocation. The discontinued WS-C3750-48TS-E is the non-PoE sibling for independently powered equipment. The powered configuration addresses existing installations that need inline endpoint power without changing their Fast Ethernet access-link requirements.

32 Gbps switching capacity carries switching traffic, while a 13.1 Mpps forwarding rate defines packet-handling performance for this hardware configuration. 370W of shared endpoint power requires allocation rather than assuming simultaneous maximum output on every powered port. OSPF, EIGRP and BGPv4 support dynamic unicast routing; PIM-SM and PIM-DM handle multicast routing alongside PBR and HSRP. WS-C3750-48PS-E contains 128 MB of DRAM and 16 MB of flash for software operation and storage. Configurable tables accommodate 12000 MAC addresses and 11000 unicast routes, with resource allocation affecting the available mix. Cisco IOS provides administrative control through console and network management connections. LACP supports aggregated links, while RSTP and MSTP control redundant Layer 2 paths. 489W measured consumption at full traffic and maximum PoE load informs loaded power planning; switch-only consumption at full traffic is 89W. Native uplinks do not provide 10G connections, so adding an optic cannot increase their interface speed.
ORM Systems offers WS-C3750-48PS-E new sealed or certified refurbished; refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port and firmware verified before configurations are wiped to factory default. ORM warranties provide up to a 3-year extended term for new units or up to 1 year refurbished, with 30-day returns on every condition; terms apply. Specify the condition and accessory PIDs on your PO; Cisco service ended July 31, 2015. Enterprise and volume orders support PO acceptance, Net-30 for government, RMA with advance replacement, and stock/RMA across the UK, EU, US and MEA.

A phone or wireless access-point rollout needs an endpoint-by-endpoint power schedule. Supported simultaneous allocations include 24 ports at 15.4W or 48 ports at 7.7W, with mixed allocations between those configurations. Record each endpoint's requested power, assigned port and combined allocation before placing the purchase order.
Adding capacity to an existing stack requires all members to run the same Cisco IOS Software version. Automatic version checking and updating operate through the master switch, so the order must account for staging rather than only chassis count. Verify the master image and new-member configuration before the PO.
Replicating an existing routed-edge configuration requires attention to virtual-interface resources rather than physical connections alone. A configuration with 128 SVIs is recommended; the maximum of 1000 depends on route and multicast entries. Specify the intended SVI count and route-resource allocation before ordering hardware for the configuration.
Gigabit copper access links
WS-C3750-48PS-E supports 10/100 Mbps on copper access ports, not Gigabit Ethernet. Its Gigabit interfaces are SFP uplinks and cannot satisfy a requirement for native Gigabit copper access.
PoE+ power for attached endpoints
WS-C3750-48PS-E supplies IEEE 802.3af PoE at 15.4W per port, not PoE+. Endpoints requiring higher per-port power cannot receive that power requirement from these access ports.
Native 10G uplinks to distribution
WS-C3750-48PS-E has 1G SFP uplinks without a native 10G uplink interface. C9300L-48P-4X-A provides four 10G uplinks with 48 PoE ports and Network Advantage instead of IP Services.

WS-C3750-48PS-E identifies a Catalyst 3750 switch: WS-C3750 is the family prefix, 48 denotes 48 10/100 Ethernet ports, PS combines PoE access ports with SFP uplinks, and E denotes IP Services. The configuration includes four Gigabit SFP uplink interfaces rather than Gigabit copper access ports.
WS-C3750-48PS-E supports a console CLI, Telnet, SSH with a cryptographic image, Cisco Network Assistant web management, Cisco CMS Software, browser-based initial setup, CiscoWorks and SNMPv1/v2c/v3. SSH and encrypted SNMPv3 require the cryptographic software image; specify that image requirement when preparing secure remote administrative access.
Yes, WS-C3750-48PS-E ended Cisco sales on July 5, 2010, and Cisco support ended July 31, 2015. Its immediate replacement, WS-C3750V2-48PS-E, is also discontinued. The forward replacement chain continues through discontinued WS-C3650-48PS-E to C9300L-48P-4G-A for current-generation procurement rather than another discontinued intermediate model.
ORM Systems offers WS-C3750-48PS-E 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 are available for 30 days in either condition; terms apply. Cisco's original limited lifetime coverage and service ended July 31, 2015.
IP Services is the included software image on WS-C3750-48PS-E, enabling advanced unicast, multicast and hardware-based IPv6 routing. The IP Base alternative supplies static routing, RIP and EIGRP stub functionality. State the required image on the purchase order rather than treating every Catalyst 3750 software variant as equivalent.
WS-C3750-48PS-E shares 370W of PoE power across its powered access ports, rather than providing maximum power on every port simultaneously. Supported allocations include 24 ports at 15.4W or 48 ports at 7.7W. Check each endpoint's requested power and the combined allocation before finalizing the order.
The Catalyst 3750 Gigabit SFP uplinks accept GLC-SX-MM= for multimode fiber and GLC-LH-SM= for single-mode fiber. GLC-T= provides a copper Gigabit transceiver option. Specify transceiver PIDs, link media and the far-end interface together; an SFP cage alone does not establish a complete uplink connection.
Cisco StackWise stacks nine Catalyst 3750 members over a 32-Gbps interconnect using dedicated stack connections. Cable choices are CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M=. Catalyst 3750 and Catalyst 3750-E members can share a stack; verify matching Cisco IOS Software versions and cable reach before adding hardware.
The Catalyst 3750 IP Services image supports static routing, RIPv1, RIPv2, RIPng, OSPF, EIGRP, BGPv4, OSPFv6, EIGRPv6 and PBR, together with PIM-SM, PIM-DM and PIM sparse-dense mode. Plan route and multicast resources together; 128 SVIs are recommended, while larger SVI counts depend on those resource allocations.
WS-C3750-48PS-E provides PoE on its 48 Fast Ethernet access ports, while WS-C3750-48TS-E has 48 non-PoE Fast Ethernet access ports. Both carry four Gigabit SFP uplinks and IP Services, and both are discontinued. The powered model suits inline-powered endpoints; the non-PoE model suits separately powered equipment.
WS-C3750-48PS-E includes IP Services, whereas WS-C3750-48PS-S includes IP Base; both are discontinued 48-port Fast Ethernet PoE switches with four Gigabit SFP uplinks. IP Services suits advanced routed or multicast configurations. IP Base suits installations limited to its static, RIP and EIGRP stub routing capabilities.
WS-C3750-48PS-E is discontinued and passed its last Cisco support date on July 31, 2015; C9300L-48P-4G-A is the current endpoint of its replacement chain. The older model serves existing-hardware matching requirements, while the successor is the procurement path when a current-generation replacement is required.
The 48-port Fast Ethernet PoE switch uses an internal autoranging AC supply accepting 100-240V AC, with external redundant power through PWR-RPS2300 or PWR675-AC-RPS-N1=. Redundancy does not come from a second internal supply. CAB-RPS2300= or CAB-RPS-1614= must match the selected external power system.
WS-C3750-48PS-E occupies a 1U rack position and measures 44 mm high, 445 mm wide and 378 mm deep, weighing 6 kg. Its operating temperature range is 0°C to 45°C, and MTBF is 166408 Hours. Verify rack depth, ambient temperature and chassis handling requirements before ordering hardware.
