SG550XG-8F8T-K9-UK combines eight 10GBase-T access connections with eight fixed 10G SFP+ uplinks in a managed, non-PoE switch for small and medium business aggregation. Its Layer 2+ capabilities include routed VLAN connectivity, while the full-width 1U chassis mounts in a standard equipment rack. The Cisco 550X Series connects copper-attached servers and storage with fiber-connected access switches. Unlike shared combo interfaces, the copper and fiber connections on this model remain independently available. Compared with the discontinued SG550X-24P-K9-UK, this model provides native 10G copper connectivity rather than powered Gigabit access. A dedicated Gigabit out-of-band management connection separates administrative access from production-facing interfaces. The mixed-media configuration accommodates maintenance orders that must preserve an existing copper and fiber connection layout.

320 Gbps switching capacity supports full-duplex traffic across the data interfaces. 238.08 Mpps forwarding handles 64-byte packets at wire speed. Static routing and RIP v2 provide routed connectivity; VRRP versions 2 and 3 support default-gateway redundancy, while PBR directs selected traffic by policy. The SG550XG-8F8T supports 32000 MAC entries and 7168 IPv4 routes, with 256 IP interfaces for routed configurations. SG550XG-8F8T-K9-UK combines 512 MB of DRAM, 256 MB of flash and a 2 MB packet buffer shared dynamically across all ports. STP, RSTP and MSTP control bridged loops, while LACP combines links into aggregated connections. Browser configuration, Textview CLI, SSH and SNMP provide administrative access. Four fans provide N+1 cooling redundancy. 84.6W worst-case system consumption provides the chassis allowance for rack power sizing. Internal hot-swappable PSU redundancy is absent; backup power uses an external redundant-power connection rather than a second internal supply bay.
ORM Systems offers SG550XG-8F8T-K9-UK new sealed or certified refurbished, with up to a 3-year extended warranty on new units, up to 1 year on certified refurbished units, and 30-day returns on every condition; terms apply. Certified refurbished units are inspected and bench-tested, with every port linking at rated speed, optics bay recognition checked, firmware verified and configuration wiped to factory default. Specify the condition, quantity and required accessories on the purchase order; Cisco's original limited lifetime hardware warranty and service coverage ended June 30, 2025. Enterprise and volume orders support POs, Net-30 for government, and RMA with advance replacement.

An existing 550X installation requiring another member can mix SF550X, SG550X, SG550XG and SX550X switches in one hardware stack. Ring and chain topologies use standard network interfaces rather than dedicated stacking connectors. Reserve the interconnect ports and specify the topology and stack-member configuration before the purchase order.
When several connections must terminate as aggregated bundles, the 550X supports 32 link aggregation groups with eight active ports per group and 16 candidates for dynamic aggregation. Physical interface availability still limits the bundles on an individual unit; specify member assignments and connection media before ordering.
A staging bench preparing repeated orders can retain two firmware images and load text-editable configurations through SCP. The USB Type-A interface also transfers image and configuration files. Specify the target firmware, configuration file and required staging checks before releasing the hardware purchase order for the rollout batch.
Active Cisco hardware service coverage
Cisco service for SG550XG-8F8T-K9-UK ended June 30, 2025. C1300-16XTS is the current migration endpoint, retaining eight 10G copper ports and eight SFP+ ports.
PoE-powered phones or wireless access points
SG550XG-8F8T-K9-UK provides no PoE on its copper interfaces. Endpoints requiring power through the Ethernet connection therefore need a separate power source or powered access equipment.

SG550XG-8F8T-K9-UK identifies the UK-region 550X managed 10G switch with eight SFP+ ports and eight 10GBase-T ports. The 8F8T segment matches that fiber/copper split. UK also covers Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong and Malaysia. K9 remains part of the complete regional ordering code.
SG550XG-8F8T-K9-UK supports an HTTP/HTTPS web interface, Textview CLI through console, SSH or Telnet, SNMP, Smart Network Application, FindIT Network Manager with an embedded Probe, and Active Advisor. FindIT Network Discovery Utility provides browser-based discovery, while Network Plug and Play supports provisioning. A dedicated Gigabit port provides out-of-band management access.
SG550XG-8F8T-K9-UK is discontinued: end of sale was June 18, 2020, and Cisco service ended June 30, 2025. Software maintenance ended June 18, 2021. Its original successor, SX550X-16FT-K9-UK, is also discontinued; the migration chain continues through discontinued CBS350-16XTS-UK to current C1300-16XTS.
ORM Systems offers SG550XG-8F8T-K9-UK new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Both conditions have 30-day returns; terms apply. Cisco's original limited lifetime hardware warranty and service ended June 30, 2025. Refurbished units are inspected, bench-tested, firmware verified and wiped to factory default.
The SG550XG-8F8T accepts SFP-10G-SR and SFP-10G-SR-S for multimode fiber, plus SFP-10G-LR and SFP-10G-LR-S for single-mode links reaching 10 km. SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M provide 1 m, 3 m and 5 m copper-coax connections. Match the media, distance and interface at both ends before ordering.
A 550X hardware stack supports eight members and can mix SF550X, SG550X, SG550XG and SX550X models. Standard 10G copper or fiber connections provide interconnects, with ring or chain topology and link aggregation available. SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M are supported copper-coax cable choices for the connections.
The 550X supports IPv4 static routing and RIP v2 between routed interfaces, with 7168 IPv4 routes and 256 IP interfaces. VRRP versions 2 and 3 provide gateway redundancy, and PBR supports policy-directed forwarding. Its IPv6 static-routing limit is 1792 routes with 256 IPv6 interfaces; size both address families separately.
No, SG550XG-8F8T-K9-UK does not offer a second internal redundant PSU bay; backup power uses an external RPS connection. The internal universal supply accepts 100-240V AC at 47-63 Hz. Maximum system draw is 84.6W, so size rack power around chassis consumption rather than a PoE allowance.
Yes, the SG550XG-8F8T is a full-width 1U rack-mount switch measuring 440 mm wide, 44 mm high and 350 mm deep, with a weight of 5.23 kg. Four fans provide N+1 cooling redundancy. The operating range is 0°C to 50°C, so confirm rack depth and ventilation before ordering.
SG550X-24P-K9-UK provides PoE+ with a shared 195W budget, while SG550XG-8F8T-K9-UK supplies no PoE. Both models are discontinued. SG550X-24P-K9-UK addresses powered Gigabit access requirements; SG550XG-8F8T-K9-UK addresses separately powered 10G equipment. Buyers maintaining existing installations should distinguish endpoint power requirements before selecting either historical model for a like-for-like maintenance order.
SG550XG-24F-K9-UK has 24 SFP+ interfaces, including two shared with copper, while SG550XG-8F8T-K9-UK has eight dedicated SFP+ interfaces. Both models are discontinued. The former addresses fiber-heavy installed networks; the latter preserves an even split between dedicated copper and fiber connections for maintenance orders.
C1300-16XTS is the current migration endpoint for SG550XG-8F8T-K9-UK, whose Cisco service ended June 30, 2025. Both configurations provide eight 10G copper ports and eight SFP+ ports. The older model addresses like-for-like maintenance of an installed estate; C1300-16XTS addresses a replacement purchase beyond the retired hardware line.
