WS-C3750V2-48PS-E is a Layer 3 Fast Ethernet PoE access switch with 48 10/100Mbps copper ports and four fixed Gigabit SFP uplinks in a rack-mount 1U chassis. The Cisco Catalyst 3750 v2 configuration includes IP Services for enterprise, retail, and branch networks retaining Fast Ethernet endpoint connections. Compatible IP phones and wireless access points receive power over their access connections, while the SFP positions provide distribution-facing links. Discontinued WS-C3750V2-48TS-E retains the same access speeds and uplink arrangement without PoE. The 48-port PoE access switch combines endpoint connectivity with routed-access functionality. Voice VLANs separate telephone traffic from data traffic, and access controls can apply at the port, VLAN, or routed interface. This configuration supports legacy endpoint requirements rather than Gigabit copper access.

32 Gbps switching capacity defines the switching fabric's bandwidth, while 13.1 Mpps forwarding sets the packet-rate ceiling for this configuration. 370W of shared PoE output requires allocation across powered connections rather than maximum power at every port. OSPF, EIGRP, BGPv4, and PBR support unicast routing and traffic-path policies under the installed image. WS-C3750V2-48PS-E has 32 MB of flash for local software storage. Resource templates trade address-learning capacity against route capacity: 12000 MAC entries belong to the VLAN template, whereas the routing template supports 11000 total unicast routes. Those figures represent different configurations, not simultaneous maxima. Console access and cryptographic SSHv2 sessions provide administrative access; DHCP snooping and Dynamic ARP Inspection protect the access edge. 458W input consumption at full throughput with maximum PoE loading provides a measured reference for loaded electrical demand, rather than treating the endpoint power budget as total switch consumption.
Order WS-C3750V2-48PS-E in new sealed or certified refurbished condition, and specify the required accessories and software image on the PO. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, and PoE output under load on every powered port; firmware is verified and configuration wiped to factory default. New units carry up to a 3-year extended ORM warranty and certified refurbished units up to 1 year, with 30-day returns on either condition, terms apply; Cisco service ended May 31, 2021. Enterprise and volume orders accept POs, government Net-30, and RMA with advance replacement across UK, EU, US, and MEA.

When replacing powered endpoints without changing Fast Ethernet access links, compare endpoint requests with the available allocation. The switch supports 24 ports at 15.4W or 48 at 7.7W, with mixed allocations between those configurations. Record each phone or access point's power requirement before finalizing the PO.
When extending an existing stack, verify the installed members and software before adding hardware. StackWise supports mixed Catalyst 3750 v2, discontinued Catalyst 3750, and discontinued Catalyst 3750-E members. Select CAB-STACK-50CM=, CAB-STACK-1M=, or CAB-STACK-3M= to match the physical reach, and specify the required cable lengths on the PO.
When buying a bench unit for fault isolation, stage the software and monitoring settings used in production. Embedded RMON supplies four groups covering history, statistics, alarms, and events, while RSPAN supports remote port observation. Specify the required monitoring configuration and test interfaces before issuing the purchase order.
Gigabit speeds on endpoint ports
WS-C3750V2-48PS-E limits copper access links to 10/100Mbps. C9300L-48P-4G-A provides 48 Gigabit copper access ports and is the current endpoint of the migration chain.
PoE+ power for connected endpoints
WS-C3750V2-48PS-E supplies IEEE 802.3af PoE at 15.4W per port, not PoE+. C9300L-48P-4G-A supports PoE+ while retaining 48 copper access ports.
10G uplinks to distribution
The four built-in SFP uplinks operate at 1G, and the chassis has no removable uplink-card bay. A 10G requirement exceeds this switch's fixed uplink architecture.

WS-C3750V2-48PS-E identifies a Catalyst 3750 v2 switch with 48 Fast Ethernet PoE ports, four Gigabit SFP uplinks, and IP Services. WS-C3750V2 is the series identifier, 48 is the access-port count, PS denotes the PoE/SFP configuration, and E denotes the enhanced IP Services image.
WS-C3750V2-48PS-E supports Cisco IOS CLI through the console, SSHv2, or Telnet, web-based Express Setup, SNMPv1/v2c/v3, Cisco Network Assistant, and CiscoWorks LMS. SSHv2 requires a cryptographic software image. Express Setup handles initial browser-based configuration; the CLI provides switch configuration and operational access.
WS-C3750V2-48PS-E is discontinued: end of sale was May 14, 2016, and Cisco support ended May 31, 2021. WS-C3650-48PS-E was its direct replacement but is also discontinued. The forward migration chain now ends at C9300L-48P-4G-A, rather than at the older Catalyst 3650 model.
ORM Systems offers WS-C3750V2-48PS-E 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 in either condition; terms apply. Cisco's original limited lifetime hardware warranty no longer provides service, which ended May 31, 2021.
IP Services is preinstalled on WS-C3750V2-48PS-E; IP Base is the other software configuration in the Catalyst 3750 v2 family. IP Services includes advanced unicast and multicast routing, PBR, and IPv6 routing. CD-3750-EMI= is the IP Base-to-IP Services upgrade for an existing lower-tier switch.
WS-C3750V2-48PS-E replaced discontinued WS-C3750-48PS-E, whose end-of-sale date was July 5, 2010. The older model also provided 48 10/100 PoE ports and four SFP uplinks. The v2 unit remains a legacy maintenance option, not a current-generation replacement, because its own Cisco service period has ended.
370W is the shared PoE budget for WS-C3750V2-48PS-E, with a maximum of 15.4W at an individual port. The power allocation supports 24 ports at 15.4W or 48 ports at 7.7W, including mixed combinations between those cases. All 48 ports cannot receive 15.4W simultaneously.
Catalyst 3750 v2 PoE switches accept GLC-SX-MM=, GLC-LH-SM=, GLC-ZX-SM=, and GLC-T= in their Gigabit SFP uplinks. The 48-port configuration has four built-in uplink positions. Select the transceiver against the installed fiber or copper medium and the matching far-end interface; these are not 10G SFP+ uplinks.
Nine switches can form a Catalyst 3750 v2 StackWise stack over the 32 Gbps interconnect. Compatible members include Catalyst 3750 v2 and the discontinued Catalyst 3750 and Catalyst 3750-E families. Cable options are CAB-STACK-50CM=, CAB-STACK-1M=, and CAB-STACK-3M=; select lengths for the physical stack layout.
Yes, WS-C3750V2-48PS-E supports OSPF and BGPv4 with IP Services. The same feature set includes EIGRP and PBR, plus IPv6 routing. The routing template supports 11000 total unicast entries, split between 3000 directly connected hosts and 8000 indirect routes; other templates allocate resources differently.
No, WS-C3750V2-48PS-E uses an internal AC supply and external redundancy through PWR-RPS2300 rather than a second internal supply. CAB-RPS2300-E= is the compatible spare connection cable. PWR-RPS2300 can connect six switches and back up two simultaneously, so six connections do not mean six simultaneous backup loads.
WS-C3750V248PSE-RF is the discontinued Cisco-remanufactured form of the 48-port PoE IP Services configuration, separate from the base WS-C3750V2-48PS-E PID. Cisco remanufacturing and reseller-certified refurbishment are different processes. The remanufactured form does not restart the hardware family's support lifecycle; Cisco service for this switch ended May 31, 2021.
WS-C3750V2-48PS-E supplies PoE on its copper access ports, while discontinued WS-C3750V2-48TS-E is the non-PoE configuration. Both retain 48 10/100 access ports and four Gigabit SFP uplinks. The PoE model addresses legacy powered-endpoint requirements; the discontinued non-PoE variant corresponds to installations that power their endpoints separately.
WS-C3750V2-48PS-E includes IP Services, whereas discontinued WS-C3750V2-48PS-S includes IP Base on the same port configuration. IP Services adds advanced routing, PBR, and IPv6 routing beyond the basic routing feature set. The enhanced image suits legacy routed-access requirements; IP Base corresponds to installations needing the lower software tier.
C9300L-48P-4G-A provides Gigabit copper access ports, while WS-C3750V2-48PS-E is limited to 10/100Mbps copper access. The current model is the forward migration endpoint after discontinued WS-C3650-48PS-E. Retaining the older switch suits an existing Fast Ethernet maintenance requirement; Gigabit endpoint requirements point to the current replacement.
