WS-C4948E-E provides 48 copper Gigabit Ethernet connections and four fixed 10G SFP+ uplinks in a 1U chassis for server switching. This managed Layer 3 model combines the Catalyst 4948E hardware with Enterprise Services software and an AC power supply. The Cisco Catalyst 4948E Ethernet Switch uses front-to-back airflow, making airflow direction an important distinction when matching an existing rack installation. Its fixed interfaces provide separate server-facing and uplink connections without a removable uplink card. Within the discontinued family, WS-C4948E-S carries IP Base software rather than Enterprise Services; the software package, not additional physical interfaces, separates those two configurations.
WS-C4948E-E price for new stock is $26,565.00. WS-C4948E-E refurb price is $1,985.63. WS-C4948E-E is in stock and available for free next-day delivery. (terms applied)

131 Mpps forwarding performance supports hardware packet forwarding, while a 57000-route capacity provides the published routing scale for this hardware. BGP is included in Enterprise Services, allowing the routed configuration to use that protocol without changing the physical interfaces. A 300W maximum power-consumption figure provides the electrical planning allowance rather than an endpoint-power budget. WS-C4948E-E accepts optional internal power redundancy; PWR-C49E-300AC-R/2 is the matching additional AC supply option. The Catalyst 4900 family software environment runs Cisco IOS rather than NX-OS. Redundant fans provide active chassis cooling, so installation planning must preserve the chassis airflow path.
ORM Systems offers WS-C4948E-E new sealed and certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot, optics bay recognition, PSU status and fan status, with firmware verified and configuration wiped to factory default. Specify condition, quantity and the required power configuration on the PO. ORM warranty is up to a 3-year extended term for new hardware and up to 1 year for certified refurbished hardware, with 30-day returns on every condition, terms apply; Cisco coverage ended October 31, 2022.

This configuration delivers sub-microsecond latency, micro-segmentation via Cisco TrustSec, and non-stop forwarding to sustain 24/7 transaction processing. Outcome: 60% higher east-west throughput, 40% lower packet loss, and simplified spine-leaf scaling under a single management pane.
A university deploys WS-C4948E-E Catalyst 4948E switches across its smart campus to power 48 PoE+ endpoints per building zone (Wi-Fi 6 APs, VoIP phones, environmental sensors) with dual-stack IPv4/IPv6. Integrated Cisco Unified Power Over Ethernet ensures 740W per chassis with hot-swap power supplies. Outcome: Centralized remote power provisioning, 99.99% uptime for AV/IoT services, and 30% reduction in rack space and cable clutter.
A financial institution integrates WS-C4948E-E Catalyst 4948E into its virtualized trading floor network to interconnect 48 virtual machine hosts at 10GbE with redundant 40GbE spine uplinks. Leveraging Cisco FabricPath and Priority Flow Control, the switch delivers deterministic sub-200μs latency and lossless traffic for high-frequency trading. Outcome: 25% faster order execution, seamless VM mobility, and end-to-end QoS guaranteeing SLAs for mission-critical applications.
An existing installation using the discontinued WS-C4948-E or WS-C4948-10GE-E may have standardized on this replacement during an earlier refresh. Treat that history as a compatibility starting point, not a complete migration plan. Before the PO, check the retained configuration, rack installation and existing uplink connections against the replacement hardware.
A lab reproducing an older production environment needs a defined software baseline before hardware is accepted. The Catalyst 4948E default image was 12.2(54)SG1, but an acquired unit can carry a different installed release. Specify the required software image and configuration acceptance checks before placing the staging order.
10G copper server access
The 48 copper access interfaces stop at Gigabit Ethernet; the separate 10G connections use SFP+ cages. A requirement for native 10G copper downlinks exceeds this configuration.
Active Cisco hardware service
Cisco service for this hardware ended October 31, 2022. A deployment requiring an active Cisco hardware support entitlement cannot meet that requirement with this discontinued model.

WS-C4948E-E identifies a Catalyst 4948E configuration with Enterprise Services software, 48 copper 10/100/1000 ports, four SFP+ uplinks and AC power. WS-C4948E is the hardware identifier, while the final -E selects Enterprise Services. Keep the complete identifier on the PO to distinguish this bundle from the software-optional base hardware.
The Catalyst 4948E runs Cisco IOS Software, with the Enterprise Services image supplied in WS-C4948E-E. Configuration and software-image selection belong to the switch's managed operating environment rather than an unmanaged plug-and-play workflow. For a replacement order, specify the required image and the configuration acceptance checks alongside the hardware condition.
Enterprise Services is the software package supplied with WS-C4948E-E, and BGP is included in that package. The final suffix selects the software configuration rather than adding physical Ethernet interfaces. When retaining an existing routed configuration, specify Enterprise Services explicitly so the quoted hardware and software combination matches the intended order.
Yes, WS-C4948E-E is discontinued, with original Cisco sales ending October 31, 2017, and the last date of support passing on October 31, 2022. Cisco service has ended for this hardware. A purchase therefore needs an independent hardware-support plan rather than an expectation of a new Cisco service entitlement.
ORM Systems offers WS-C4948E-E new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year. Returns cover 30 days in either condition, terms apply. Cisco hardware warranty coverage and service ended October 31, 2022; ORM coverage is separate from Cisco's ended coverage.
WS-C4948E-E was named as a replacement for the discontinued WS-C4948-E and WS-C4948-10GE-E. The older models used different uplink interfaces, so a historical replacement relationship does not make existing uplink hardware interchangeable. Check the installed connections and configuration before ordering; the replacement model is itself discontinued and beyond Cisco support.
WS-C4948E-E has four fixed 10G SFP+ uplink ports in addition to its 48 copper Gigabit access ports. The uplinks are built into the chassis rather than supplied by a removable uplink card. Before ordering, identify the required uplink connections separately from the copper server connections and confirm the intended optical configuration.
Yes, WS-C4948E-E includes BGP through its Enterprise Services software image. BGP capability belongs to that software package, not to an additional physical interface card. For an existing routed installation, make the required image part of hardware acceptance and verify the retained routing configuration before introducing the replacement unit into service.
Yes, WS-C4948E-E supports optional internal AC power redundancy, with PWR-C49E-300AC-R/2 identified as the additional AC supply option. The AC-powered bundle should not be assumed to contain the optional second supply. Specify the required supply quantity on the PO and confirm the quoted power configuration before accepting the order.
WS-C4948E-E includes Enterprise Services software, while WS-C4948E-S includes IP Base software. Both configurations have 48 copper Gigabit interfaces, four SFP+ uplinks and AC power. Both are discontinued; the Enterprise Services configuration suits an existing requirement for that image, while the IP Base configuration matches installations standardized on IP Base.
WS-C4948E-E uses front-to-back airflow, while WS-C4948E-F-E uses back-to-front airflow. Both configurations include Enterprise Services software and AC power, and both are discontinued. The original configuration matches racks requiring front-to-back chassis cooling; the -F configuration matches the opposite airflow requirement and should not be substituted without checking rack orientation.
WS-C4948E-E includes an AC power supply, while the WS-C4948E base hardware excludes a power supply. Both identifiers belong to the discontinued Catalyst 4948E family. The bundled configuration suits a purchase requiring included AC power; the base hardware requires a separately specified power configuration before it can be treated as a complete order.
The Catalyst 4948E occupies 1U and measures 44.45 mm high, 444.5 mm wide and 492.76 mm deep. Rack planning must account for chassis depth as well as vertical space. Confirm mounting arrangements, cable clearance and airflow orientation before the PO rather than treating the rack-unit height as the complete installation requirement.
Allow 300W maximum power consumption for WS-C4948E-E when planning the rack's electrical load. That figure describes the switch rather than a PoE allocation for connected endpoints. Optional power redundancy changes the supply configuration, so specify the intended power arrangement separately from the electrical allowance used for the hardware purchase.
