WS-C3750E-48PD-SF provides 48 Gigabit Ethernet PoE access ports and two fixed 10G X2 uplink interfaces in a managed Layer 3 switch. The full-power configuration supports enterprise wiring closets carrying powered phones, wireless access points, and conventional Ethernet endpoints. Its uplinks use X2 interfaces rather than SFP+ cages, so existing optics must match that interface architecture. Cisco Catalyst 3750-E hardware occupies one rack unit and combines access switching with the IP Base feature set. The discontinued WS-C3750E-48PD-S sibling has a smaller 420W endpoint-power allocation, making power demand the principal distinction between these otherwise equivalent port configurations. Voice VLAN separates telephone traffic from data traffic, while access controls and traffic classification support an established enterprise configuration without implying that the advanced IP Services routing features are enabled.

160 Gbps switching capacity accommodates local switching across the access and uplink interfaces. 101.2 Mpps forwarding supports the full-power 48-port hardware configuration, while the separate stack-forwarding figure is 95 Mpps for 64-byte packets. 800W of shared PoE capacity requires aggregate endpoint demand to remain within the available allocation. Static routing, RIPv1, RIPv2, RIPng, and EIGRP Stub provide the IP Base routing options; OSPF, BGPv4, full EIGRP, and PIM routing require IP Services. WS-C3750E-48PD-SF carries 256 MB of DRAM and 64 MB of flash for its operating software and configuration. Resource allocation changes with the selected memory template: the default provides 6000 MAC entries, while the routing template supports 11000 total unicast routes. 978W measured consumption at full throughput with maximum tested PoE loads informs facility sizing; the corresponding unloaded measurement is 152W. The C3K-PWR-1150WAC supply rating is not the measured switch draw.

When extending an existing Catalyst 3750 stack, record the installed member software and available rear connections before ordering a Catalyst 3750-E unit. CAB-STACK-1M= provides a 1 m connection and CAB-STACK-3M= a 3 m connection. Measure the cabinet cable route and specify the required cable lengths on the PO.
When preparing configuration templates before a hardware replacement, account for the Catalyst 3750-E limit of 1005 VLANs rather than treating the VLAN identifier range as usable configuration capacity. Map the required voice and data segments, identify reserved assignments, and check the planned configuration before specifying the staged unit on the PO.
When preparing spare inventory for sites in the UK, EU, US, or MEA, separate complete-switch requirements from accessory requirements before submitting the PO. ORM supports regional stock and RMA handling across those regions. Record the installed hardware variant, required quantities, condition, and destination for each replenishment order.
Standard PoE+ endpoint power
WS-C3750E-48PD-SF provides PoE with proprietary Enhanced PoE capped at 20W per port, not standard PoE+. C9300-48P-A provides a 48-port PoE+ alternative.
Two internal power supplies
WS-C3750E-48PD-SF has one internal power-supply slot. A second internal supply cannot be installed; backup power requires an external redundant power system rather than another chassis supply.
Active Cisco service coverage
WS-C3750E-48PD-SF passed its last date of support on January 31, 2018. C9300-48P-A is the current endpoint of its replacement chain.

WS-C3750E-48PD-SF identifies a Catalyst 3750-E configuration: 48 denotes 48 access ports, P denotes PoE, D corresponds to two 10G X2 uplinks, S selects IP Base, and F distinguishes the full-power configuration. The F version ships with C3K-PWR-1150WAC and provides an 800W shared PoE budget.
WS-C3750E-48PD-SF supports the Cisco IOS CLI through its console connection and Telnet, with SSH available through a cryptographic software image. Additional management paths include SNMP, the PC-based Cisco Network Assistant application, and CiscoWorks LAN Management Solution. A stack is administered as one object with one management IP address.
WS-C3750E-48PD-SF reached end of sale on January 30, 2013, and its last date of support was January 31, 2018. Software maintenance ended January 30, 2014, followed by vulnerability support on January 30, 2016. Existing installations therefore need replacement planning that does not depend on continuing Cisco service.
WS-C3750E-48PD-SF is offered new sealed or certified refurbished, with ORM warranties of up to 3-year extended coverage for new units and up to 1 year for refurbished units. Returns are 30 days for every condition; terms apply. Cisco’s original 90-day limited hardware and software warranty is ended; Cisco support ended January 31, 2018.
IP Base is the WS-C3750E-48PD-SF as-shipped feature set; IP Services is the upgrade tier. Cisco IOS Software Activation enables the selected feature set. For used equipment, LL-3750E-IPB= and LL-3750E-IPS= are the respective relicensing parts; 3750E48-IPSLCB-QTY is the 48-port IP Base-to-IP Services upgrade.
WS-C3750E-48PD-SF provides an 800W shared PoE budget, with standard PoE supporting 15.4W on all 48 access ports. Proprietary Enhanced PoE supports a 20W per-port ceiling, but that ceiling cannot be assigned simultaneously to every port. Aggregate allocations must remain within the available shared budget.
The Catalyst 3750-E uses two 10G X2 uplink interfaces, with X2-10GB-SR= among its compatible transceivers. CVR-X2-SFP converts an X2 interface into two 1G SFP interfaces when Gigabit uplinks are required. Select the interface configuration first, then match the transceiver type to the installed fiber and remote equipment.
A Catalyst 3750-E StackWise Plus stack contains nine members and provides 64 Gbps stack throughput. Compatible cable options include CAB-STACK-50CM=, CAB-STACK-1M=, and CAB-STACK-3M=. StackWise Plus also supports mixed operation with Catalyst 3750 members. Specify cable lengths from the physical cabinet layout rather than assuming every connection needs the shortest cable.
WS-C3750E-48PD-SF does not enable OSPF or BGPv4 with its IP Base feature set; those protocols require IP Services. IP Base provides Static routing, RIPv1, RIPv2, RIPng, and EIGRP Stub. PBR and PIM multicast routing also require IP Services, so advanced routing requirements need a verified feature-set entitlement.
No, WS-C3750E-48PD-SF has one internal power-supply slot and ships with C3K-PWR-1150WAC. Internal dual-supply redundancy is therefore unavailable. An external redundant power connection provides the separate backup path. The installed C3K-PWR-1150WAC also determines the applicable input-voltage range, so power and redundancy requirements should be specified separately.
WS-C3750E-48PD-SF provides an 800W PoE budget, whereas WS-C3750E-48PD-S provides 420W. Both are discontinued Catalyst 3750-E configurations with the same access-port density. The SF model suits existing installations needing the larger endpoint-power allocation; the S model suits replacement requirements whose aggregate powered-device demand fits its smaller budget.
WS-C3750E-48PD-SF ships with IP Base, while WS-C3750E-48PD-EF ships with IP Services. Both configurations are discontinued. IP Base suits established access installations using its basic routing options; IP Services suits existing installations requiring advanced unicast routing, multicast routing, or policy-based routing. Confirm the installed license when ordering used hardware.
C9300-48P-A is the current migration endpoint, while WS-C3750E-48PD-SF passed its Cisco last date of support on January 31, 2018. The replacement chain passes through the discontinued WS-C3750X-48PF-S and WS-C3850-48F-S. The older model serves installed-hardware replacement needs; C9300-48P-A suits procurement requiring a current migration destination.
The full-power Catalyst 3750-E occupies 1U and measures 44.5 mm high, 445 mm wide, and 552 mm deep. Its 9.5 kg weight and chassis depth matter when checking cabinet support and clearance. RCKMNT-E-1RU= is the compatible spare rack-mount kit when replacement mounting hardware is required.
WS-C3750E-48PD-SF measured 978W at full throughput with maximum tested PoE loads and 152W at full throughput without PoE loads. These are laboratory measurements, not a guaranteed draw for every installation. The C3K-PWR-1150WAC rating is a supply limit, while actual consumption varies with traffic and connected powered devices.
