SF500-48MP combines 48 Fast Ethernet PoE+ access ports with four fixed Gigabit uplinks in a managed Layer 2+ switch for small-business networks. Two uplinks offer shared copper/SFP connections, while two additional SFP connections provide fiber connectivity. The rack-mount 1U chassis belongs to the Cisco 500 Series Stackable Managed Switches, connecting powered Ethernet endpoints without separate local adapters. The discontinued SF500-48P allocates 375W to PoE, whereas this variant provides a shared 740W budget. The higher allocation distinguishes the model within its access-switch family, but does not mean every powered port can operate at its individual maximum simultaneously. Copper or fiber selection depends on the installed connection type, with each combo interface operating through one medium at a time.
SF500-48MP price is $1,811.25, a 50% saving from the Cisco list price of $3,622.50. SF500-48MP is in stock and available for free next-day delivery. (terms applied)

33.6 Gbps switching capacity supports nonblocking forwarding across the installed interfaces. 13.1 Mpps forwarding handles 64-byte packets at the rated packet-processing performance. Static IPv4 and IPv6 routing connects configured local subnets; RIP v2 and VRRP are not supported on this model. SF500-48MP combines 256 MB of DRAM with 32 MB of flash for operating software and configuration storage. The address table accommodates 16384 MAC entries, while IPv4 routing permits 2048 static routes and 256 interfaces. Local administration uses the browser-based HTTP/HTTPS interface, Textview CLI, SSH, Telnet and SNMP versions 1, 2c and 3. STP/RSTP/MSTP provide loop prevention, and LACP aggregates compatible links. Within Cisco Small Business switching, these functions provide configurable forwarding and monitoring rather than unmanaged operation. Three fans move air through the chassis, which operates from 0°C to 50°C. The internal supply accepts 100-240V AC, so an external power adapter is not required.
SF500-48MP is offered new sealed or certified refurbished, with ORM warranties of up to a 3-year extended term for new units and up to 1 year for certified refurbished units; returns are 30 days on every condition, terms apply. Certified refurbished units are inspected and bench-tested, including PoE output under load on every powered port, firmware verification and configuration wiping to factory default. Specify condition, quantity and accessories on the purchase order; Cisco's original limited lifetime warranty and service ended December 30, 2022. Enterprise and volume orders accept POs, government Net-30 and RMA with advance replacement, with regional stock and RMA support in UK, EU, US and MEA.

A large university deploys 200+ 802.11ac Wave 2 access points across academic buildings and student residences. By stacking three SF500-48MP switches, IT staff deliver up to 30 W PoE+ per port and 70 Gbps stack bandwidth, ensuring seamless roaming, centralized VLAN segmentation, and priority QOS for video conferencing. Outcome: Reliable high-capacity Wi-Fi coverage, simplified management via a single IP stack, and a 25% reduction in network downtime.
A 1,000-employee corporate headquarters implements a voice-over-IP solution with 800 Cisco IP phones and no downtime during peak hours. The SF500-48MP switches provide consistent 48-port PoE+ support, IEEE 802.3at compliance, and per-port power scheduling to match shift patterns. Benefit: Zero dropped calls, automated power-cycle recovery, and a 40% reduction in rack space by replacing multiple single-function PoE injectors.
A city transit authority outfits 150 train stations and bus depots with 4K IP cameras, environmental sensors, and digital signage. Leveraging stacked SF500-48MP switches with dynamic PoE power allocation and advanced ACL filtering, they ensure uninterrupted video feeds and secure data separation between critical SCADA traffic and public Wi-Fi. Result: 24/7 high-definition surveillance, streamlined firmware updates, and a 30% lower total cost of ownership through energy-efficient hardware.
Extending an existing 500 Series stack requires a decision on interconnect speed and physical distance before adding another member. SFP-H10GB-CU1M provides a 1 m copper connection operating at 5G between Sx500 members. Confirm the existing stack mode, available interconnect ports and required cable length before specifying the additional unit.
Consolidating several existing access switches into one managed installation requires an uplink aggregation plan rather than another standalone connection. The 500 Series supports 32 link aggregation groups, with eight active ports per group. Before the PO, identify the participating links, confirm peer configuration and specify the copper or fiber connections required.
When a spare must be prepared ahead of a maintenance window, the two firmware images allow software to be staged separately from the active image. Configuration files can be transferred through SCP. Define the target firmware, save the intended configuration and specify boot-image verification and staging requirements on the purchase order.
10G uplinks to distribution
SF500-48MP provides Gigabit Ethernet uplinks, not 10G uplinks. C1300-48FP-4X offers four 10G SFP+ uplinks and also changes the access-port speed to Gigabit Ethernet.
Dynamic RIP routing at access
SF500-48MP supports static routing but not RIP v2 or VRRP. Networks requiring those protocols cannot use this model to perform that routing role.
30W on every powered port
A requirement for 30W simultaneously on all 48 powered ports exceeds the shared 740W budget. Full-port maximum loading is not supported by this power allocation.

SF500-48MP identifies a Fast Ethernet 500 Series switch with 48 access ports and a 740W PoE+ allocation. SF500 identifies the series and access technology, 48 gives the access-port count, and MP distinguishes the higher-power PoE+ configuration. Four fixed Gigabit uplinks are included alongside the access ports.
SF500-48MP supports a web UI over HTTP/HTTPS, Textview CLI through SSH, Telnet or serial console, and SNMP versions 1, 2c and 3. The series originally also supported Cisco OnPlus cloud services. Browser and command-line administration provide local configuration paths without depending on that historical cloud integration.
SF500-48MP is discontinued, with end of sale on December 30, 2017, and Cisco support ending December 30, 2022. Cisco hardware service and manufacturer warranty coverage have ended. A new sealed unit does not restart those milestones, so replacement and maintenance arrangements must be independent of Cisco support.
ORM Systems offers SF500-48MP new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Returns are 30 days on every condition; terms apply. Cisco's original limited lifetime hardware warranty ended with Cisco support on December 30, 2022. Refurbished units are inspected and bench-tested.
SF500-48MP provides a shared 740W PoE budget across 48 powered access ports, with a maximum of 30W per port. The individual port maximum is not available simultaneously on every port. Size the endpoint allocation against the aggregate budget, including the requested power of each connected device.
The 48-port Fast Ethernet PoE+ switch provides four Gigabit Ethernet uplinks: two copper/SFP combo interfaces and two additional SFP connections. Each combo interface uses either its copper connection or its SFP connection, not both simultaneously. The 5G interconnect capability supports stacking rather than providing 10G Ethernet uplinks.
A 500 Series hardware stack contains a maximum of eight members. Sx500 interconnects support 5G copper connections using SFP-H10GB-CU1M, SFP-H10GB-CU3M or SFP-H10GB-CU5M, with lengths of 1 m, 3 m and 5 m respectively. Select the cable length and confirm the existing stack configuration before adding another member.
Yes, SF500-48MP supports static IPv4 and IPv6 routing between configured interfaces, but does not support RIP v2 or VRRP. IPv4 routing supports 2048 static routes and 256 interfaces; IPv6 supports 2048 static routes and 128 interfaces. Configure the required routes rather than expecting dynamic route learning.
SF500-48MP occupies one rack unit in a full-width rack installation, with a chassis measuring 440 mm wide, 44 mm high and 350 mm deep. The unit weighs 5.52 kg. Allow space for power and network connections in addition to the chassis depth when specifying the installation.
SF500-48MP supplies a 740W PoE budget, whereas the discontinued SF500-48P supplies 375W across its powered access ports. Both models belong to the discontinued 500 Series. The higher-budget version suits legacy replacements with larger aggregate endpoint loads, while the lower-budget version addresses installations whose power allocation stays within 375W.
SF500-48MP has 48 Fast Ethernet access ports, while the discontinued SF500-24MP has 24. Both provide PoE+ access and four Gigabit uplinks within the discontinued 500 Series. The larger model suits legacy orders requiring more endpoint connections; the smaller model matches installations that need only the lower access-port density.
C1300-48FP-4X provides four 10G SFP+ uplinks, whereas SF500-48MP provides four Gigabit uplinks. The current migration model addresses purchases requiring 10G distribution connections. The discontinued SF500-48MP remains a legacy replacement option for installations retaining Gigabit uplinks, rather than a substitute for the newer model's uplink capability.
MGBSX1 and MGBLX1 support Gigabit fiber connections on the 500 Series: MGBSX1 uses multimode fiber over distances of 300 m, while MGBLX1 uses single-mode fiber over distances of 10 km. Match the transceiver to the installed fiber and the remote interface before specifying the optical connection.
The 500 Series 48-port Max PoE+ model draws a worst-case 853.04W with PoE at 110V, or 826.62W at 220V. System-only figures are 60.48W at 110V and 60.21W at 220V. Those system-only values exclude endpoint power and must not replace the full-load figure when sizing electrical capacity.
