WS-C3750E-48PD-EF provides 48 Gigabit Ethernet PoE access ports and two fixed 10G X2 uplink slots in a 1U, Layer 3 enterprise access switch. The Catalyst 3750-E configuration connects IP phones, wireless access points and other powered endpoints through copper access ports, while its uplinks use X2-format transceivers rather than native SFP+ cages. IP Services is the included software image, enabling dynamic routing alongside Layer 2 switching without an IP Base-to-IP Services upgrade. The discontinued WS-C3750E-48PD-E is the lower-budget sibling, with 420W available for endpoint power. The full-power configuration ships with C3K-PWR-1150WAC and accommodates one internal power supply, not a second internal bay for a redundant supply.

160 Gbps switching capacity provides the fabric for access and uplink traffic, while 101.2 Mpps forwarding establishes the packet-processing ceiling for this hardware configuration. 800W of shared PoE capacity supports simultaneous standard PoE delivery across the access ports, with allocation required when Enhanced PoE endpoints request more power. OSPF, EIGRP, BGPv4 and IS-ISv4 enable dynamic IPv4 routing; OSPFv3 and EIGRPv6 extend routing to IPv6, while PIM-SM and PIM-DM support multicast distribution. WS-C3750E-48PD-EF combines 256 MB DRAM with 64 MB flash for operation and software storage. Resource allocation depends on the selected template: the routing template accommodates 11000 total unicast routes with 3000 MAC entries, whereas the VLAN template accommodates 12000 MAC entries without unicast routes. Cisco Catalyst 3750-E Series administration supports the CLI, Cisco Network Assistant and CiscoWorks LMS. SSH requires a cryptographic software image; the Ethernet management port and RS-232 console provide separate administrative connections.
WS-C3750E-48PD-EF is available new sealed or certified refurbished, with ORM's up to 3-year extended warranty on new units and up to 1 year on certified refurbished units. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed port links and PoE output under load on every powered port; firmware is verified and configurations are wiped to factory default. Both conditions have 30-day returns, terms apply; Cisco's hardware warranty and service ended January 31, 2018. Specify condition, quantity and accessories on the PO; ORM accepts POs, provides Net-30 for government and RMA with advance replacement, with regional stock/RMA in the UK, EU, US and MEA.

When endpoint replacements increase power demand in an existing installation, Enhanced PoE introduces a 20W per-port ceiling. Individual port capability does not establish simultaneous availability across every connected device. Before the PO, check powered-device compatibility, requested power and the combined allocation, then specify the endpoint load plan alongside the hardware condition.
An existing stack requiring another physical member needs its partner hardware and cable layout checked before procurement. StackWise Plus provides 64 Gbps stack bandwidth and supports mixing with the discontinued Catalyst 3750 series. Specify CAB-STACK-50CM=, CAB-STACK-1M= or CAB-STACK-3M= according to the required connections, and confirm the software configuration before the PO.
A staging environment reproducing an installed network can use 9216-byte jumbo-frame support to validate large-frame configuration before equipment is released. Matching the switch setting alone does not establish end-to-end frame handling. Specify the test interfaces, corresponding peer settings and acceptance checks on the staging purchase order rather than leaving the frame-size requirement implicit.
30W PoE+ endpoint requirements
Enhanced PoE stops at 20W per port on this model; it is not 30W PoE+. C9300-48P-A is the current 48-port PoE+ migration model.
Two internal redundant power supplies
The chassis has one internal power-supply slot. Backup power depends on an external PWR2300-AC-RPS-N1= system, not a second supply installed inside the chassis.
Active Cisco hardware support
Cisco hardware support ended January 31, 2018, so purchasing this model does not restore manufacturer service. C9300-48P-A is the current endpoint of the replacement chain.

WS-C3750E-48PD-EF identifies a Catalyst 3750-E full-power PoE switch with IP Services. WS-C3750E identifies the series; 48 identifies the access-port count; PD identifies the PoE configuration with two 10G X2 uplinks; E identifies IP Services; F identifies the full-power configuration supplied with C3K-PWR-1150WAC and an 800W PoE allocation.
WS-C3750E-48PD-EF supports the Cisco IOS CLI, Telnet, SSH with a cryptographic image, web-based Express Setup, Cisco Network Assistant and CiscoWorks LMS. SNMPv1, SNMPv2c and SNMPv3 provide management integration. An Ethernet management port and RS-232 console provide separate administrative connections; management access must be configured for the selected method.
WS-C3750E-48PD-EF reached end of sale on January 30, 2013, and Cisco hardware support ended January 31, 2018. Its original replacement, discontinued WS-C3750X-48PF-E, led to discontinued WS-C3850-48F-E; the current migration endpoint is C9300-48P-A. An order for the older hardware does not restore Cisco support.
New sealed WS-C3750E-48PD-EF carries ORM's up to 3-year extended warranty; certified refurbished carries up to 1 year. Both have 30-day returns, terms apply. Cisco's Limited Lifetime hardware warranty ended with support on January 31, 2018; purchases before May 1, 2009 had a 90-day hardware warranty.
IP Services is included with WS-C3750E-48PD-EF and is activated through a Cisco IOS license file. Catalyst 3750-E also offers IP Base licensing and an IP Base-to-IP Services upgrade path. Used-equipment relicensing has separate LL-3750E-IPB= and LL-3750E-IPS= PIDs; confirm the required software entitlement separately from physical condition.
WS-C3750E-48PD-EF provides an 800W shared PoE allocation with C3K-PWR-1150WAC. Standard PoE can deliver 15.4W on all 48 access ports simultaneously. Enhanced PoE supports a 20W per-port ceiling, but the shared allocation does not permit every port to draw that ceiling at once; size the connected load before ordering.
Catalyst 3750-E uses X2 uplink interfaces, including X2-10GB-SR= for 10GBASE-SR and X2-10GB-LR= for 10GBASE-LR. CVR-X2-SFP converts one X2 interface into two Gigabit Ethernet SFP interfaces. Select the required optical module or converter by PID, and match the optical path before specifying the accessories on the purchase order.
StackWise Plus stacks nine Catalyst 3750-E members with 64 Gbps stack bandwidth and a single management identity. Compatible discontinued Catalyst 3750 switches can join the stack. CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M= provide different connection lengths; specify the cable layout and confirm software compatibility before adding another member.
WS-C3750E-48PD-EF supports OSPF, EIGRP, BGPv4 and IS-ISv4 with IP Services, plus OSPFv3 and EIGRPv6 for IPv6. PIM-SM and PIM-DM support multicast routing. The routing template accommodates 11000 total unicast routes and 3000 MAC entries, not the 12000 MAC entries available under the VLAN template.
No, WS-C3750E-48PD-EF has one internal power-supply slot and ships with C3K-PWR-1150WAC. External backup uses PWR2300-AC-RPS-N1= rather than a second internal module. Specify the external power arrangement separately if backup is required, and distinguish that arrangement from a chassis supplied with two redundant internal power modules.
Yes, WS-C3750E-48PD-EF is a 1U rack-mount switch measuring 44.5 mm high, 445 mm wide and 552 mm deep, with a 9.5 kg weight. RCKMNT-E-1RU= is the matching spare rack-mount kit. Confirm mounting hardware and available installation depth before assigning the chassis to a rack position.
WS-C3750E-48PD-EF provides an 800W PoE allocation, whereas WS-C3750E-48PD-E provides 420W. Both variants are discontinued. The difference distinguishes legacy sparing requirements: the EF configuration matches installations requiring the larger endpoint-power allocation, while the E configuration matches existing builds specified around the smaller shared budget.
WS-C3750E-48PD-EF includes IP Services, while WS-C3750E-48PD-SF includes IP Base. Both variants are discontinued. IP Services matches legacy configurations requiring advanced dynamic and multicast routing; IP Base matches configurations using its basic routing feature set. For replacement stock, match the required software entitlement rather than treating the suffixes as interchangeable.
WS-C3750E-48PD-EF has two fixed 10G X2 uplink interfaces, whereas C9300-48P-A uses modular uplinks. C9300-48P-A is the current endpoint of the replacement chain. The older configuration matches existing X2-based installations; the successor suits procurement that requires a removable uplink-module architecture, with the selected module specified separately.
WS-C3750E48PDEF-RF is the Cisco remanufactured equivalent of WS-C3750E-48PD-EF, not an ORM certified-refurbished unit. The Cisco remanufactured identity retains the full-power PoE configuration and IP Services feature set. Both belong to a discontinued generation; specify which refurbishment program is required rather than treating the condition labels as interchangeable.
