SF500-48P is a managed, Layer 2+ access switch with 48 Fast Ethernet PoE+ ports and fixed Gigabit uplinks. The access connections support 10/100Mbps endpoints, while four uplink interfaces connect the switch to the wider network. Two uplinks offer shared copper/SFP connections, and two SFP interfaces can also serve as stacking connections. The full-width 1U chassis belongs to the Cisco 500 Series Stackable Managed Switches family, serving small-business networks with powered phones, surveillance cameras and wireless access points. This Fast Ethernet stackable managed switch combines endpoint power delivery with copper and fiber connectivity rather than a removable uplink card. The discontinued SF500-48MP sibling increases the shared PoE allowance to 740W without increasing access-port density.

33.6 Gbps switching capacity handles the switch's aggregate traffic, while 13.1 Mpps forwarding performance applies to 64-byte packets. 375W of shared PoE power must cover the combined demand of connected powered devices. Static IPv4 and IPv6 routing provides local subnet connectivity; RIP and VRRP are not available on this model. SF500-48P carries 256 MB of memory and 32 MB of flash for its embedded software and configuration. A 16384-entry MAC table supports address learning, and 4096 simultaneous VLANs allow traffic separation. STP, RSTP and MSTP manage Layer 2 paths, while LACP supports aggregated connections. Eight hardware queues provide traffic-priority handling. Administrators can configure the switch through its browser interface or Textview CLI and monitor it through SNMP. The routing resources support 2048 IPv4 static routes and 256 IPv4 interfaces, with separate support for 2048 IPv6 static routes and 128 IPv6 interfaces.
SF500-48P is offered new sealed or certified refurbished; ORM's new units include up to a 3-year extended warranty, certified refurbished units include up to 1 year, and every condition has 30-day returns, terms apply.

In a 200-user corporate campus deploying IP telephony and high-density Wi-Fi access points, the Cisco SF500-48P 48-Port 10/100 PoE Stackable Managed Switch delivers a 375W PoE budget, intuitive stacking and centralized power management. This solution accelerates deployment by 40%, ensures uninterrupted voice and data services with redundant stack links, and reduces operational costs through advanced VLAN segmentation and QoS traffic prioritization.
A multi-store retail chain integrates PoE security cameras, point-of-sale terminals and digital signage across 50 locations using the SF500-48P 48-Port PoE Stackable Managed Switch. With power-over-Ethernet support, remote stack management and low-power idle mode, IT teams achieve real-time monitoring, centralized firmware updates and energy savings of up to 30%, while guaranteeing 24/7 operational continuity and rapid fault isolation.
A university deploys the Cisco SF500-48P switch in its library and lab buildings to separate student, faculty and IoT traffic into secure VLANs. Leveraging 48-port PoE and link-aggregation, network engineers enforce granular access controls and QoS policies for lecture streaming and research data. The result is enhanced security compliance, minimized broadcast domains and a 50% reduction in network congestion during peak hours.
When adding phones, cameras or wireless access points to an existing office network, endpoint power demand must be checked individually as well as in aggregate. Each powered port can provide 30W, but available power is shared. Specify endpoint counts and their required power before issuing the purchase order.
When extending an existing 500 Series stack, ring and chain topologies provide different interconnection arrangements. Supported mixed configurations combine Fast Ethernet and Gigabit members under 1 management IP address. Confirm the existing member types, intended topology and connection arrangement before specifying the additional switch and its interconnects.
When preparing a replacement unit before installation, 2 firmware images allow software staging without relying on a single stored image. Configuration files can be edited externally and transferred using SCP, while firmware upgrades can also start through the console. Specify the required firmware and configuration baseline before the purchase order.
Gigabit connections for every endpoint
The access ports stop at 100Mbps. C1300-48P-4X provides 48 Gigabit access connections and is the current migration target, rather than another discontinued Fast Ethernet generation.
10G uplinks to distribution
Normal uplinks operate at 1G, not 10G. C1300-48P-4X provides four 10G SFP+ uplinks and also changes the access connections from Fast Ethernet to Gigabit.
More than 30W per endpoint
Endpoints requiring more than 30W per port exceed this model's PoE+ output limit, regardless of unused power elsewhere in the shared budget.

SF500-48P identifies a 500 Series Fast Ethernet switch with 48 PoE+ access ports: SF500 identifies the Fast Ethernet member of the family, 48 is the access-port count, and P denotes the powered model. SF500-48P-K9 is the corresponding product order identifier for the same switch configuration.
The Cisco 500 Series is managed through an HTTP/HTTPS web interface, Textview full or menu CLI through the console, SSH or Telnet, and SNMP versions 1, 2c and 3. The firmware also includes Cisco OnPlus integration; local configuration and monitoring are available through the switch's own management interfaces.
SF500-48P is discontinued: end of sale was April 12, 2018, and Cisco support ended April 30, 2023. Following the subsequent replacement generations leads to C1300-48P-4X as the current migration target. The earlier 550X replacement generation is also discontinued, so migration planning should not stop at that intermediate generation.
ORM Systems offers SF500-48P new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Both conditions include 30-day returns, terms apply. Cisco's original limited lifetime hardware warranty and service ended April 30, 2023, so the warranty supplied with the order is ORM's.
SF500-48P provides 375W shared across 48 PoE+ ports, with a maximum of 30W on an individual port. The shared budget does not support every powered port at its maximum simultaneously. Check combined endpoint demand rather than treating the per-port maximum as an all-port power guarantee.
SF500-48P has four Gigabit uplink interfaces: two copper/SFP combo interfaces and two SFP interfaces that also support stacking. Each combo interface activates either its RJ-45 connection or its SFP connection, not both. Normal uplinks operate at 1G; the stacking-capable interfaces can use 5G copper interconnects.
SF500-48P supports hardware stacks of eight members, including supported mixed SF500, SG500 and SG500X configurations. Ring and chain topologies are available. Copper stacking uses SFP-H10GB-CU1M, SFP-H10GB-CU3M or SFP-H10GB-CU5M at 5G; a 10G-rated cable does not turn this switch's stacking link into a 10G connection.
SF500-48P supports IPv4 and IPv6 static routing, including routed VLAN interfaces, with 2048 IPv4 static routes and 256 IPv4 interfaces. IPv6 supports 2048 static routes and 128 interfaces. RIP and VRRP are unavailable on this model, so routed configurations use static routes rather than dynamic route exchange.
SF500-48P uses an internal universal AC supply accepting 100-240V at 47-63Hz, with maximum consumption of 437W at 110V including PoE. Consumption without PoE is 46.8W at 110V or 47.5W at 220V. Size mains capacity for the PoE-inclusive figure, not the switch-only figure.
SF500-48P is a full-width, 1U rack-mounted switch measuring 440mm wide, 44mm high and 350mm deep. The unit weighs 5.61kg and uses three fans with fan speed control. Its operating range is 0°C to 40°C, so rack planning must account for chassis depth and ambient temperature.
SF500-48MP supplies a 740W PoE budget, compared with 375W on SF500-48P, while both have 48 Fast Ethernet PoE+ access ports. Both models are discontinued. SF500-48P suits installed fleets with lower aggregate endpoint power demand; SF500-48MP accommodates higher combined demand without increasing the access-port count.
SF500-48P has 48 Fast Ethernet access ports, where SF500-24P has 24. Both provide PoE+ and four Gigabit uplink interfaces, so the distinguishing connection requirement is endpoint count. Both models are discontinued; SF500-48P suits higher-density installed fleets, while SF500-24P suits installations needing fewer access connections.
C1300-48P-4X has four 10G SFP+ uplinks, where SF500-48P provides Gigabit uplinks. C1300-48P-4X is the current migration target after the discontinued replacement generations. SF500-48P suits matching an existing Fast Ethernet installation; C1300-48P-4X suits migration requiring 10G uplinks and also changes the access connections to Gigabit.
