Cisco SG 550X vs. Cisco SG 500X -How do these compare

Power efficiency

Cisco features enhanced power efficiency protocols to help optimize consumption.  Both models have adjustable LED lighting which can be turned off to conserve power. They also feature automatic off support, with inactive lines regularly turned off.  The SG500 and SG550 also feature application integrated circuits which are designed for optimized consumption levels. In addition to these protocols, the switches also offer energy efficient ethernet support.  The SG550X features smart fans which automatically adjust speed based on switch temperatures for even more power efficiency.

Advanced features

Since its release, the 500 collection has incorporated various advancements to ensure various improvements within various network operations are made.   Both models offer high power PoE+ support, in addition to some Layer 3 features. They also offer comprehensive VLAN management tools, as well as high speed stack interconnects for improved service.  These switches offer SNMP support, provide a number of access points, provide sufficient configuration wizards and offer both simple and advanced user interfaces.  The SG 550X supports more advanced features, including better interconnects and intelligent software such as smart fans for more rounded performance.


These two switch series support stacking, with both options offering true stacking with compatible models.  You can monitor and control multiple switches through a single platform, with your protocols auto-configured for new additions.  The SG 550X will offer better performance than the SG 500X thanks to the use of more powerful interconnects. It also offers link aggregation which improves stacking bandwidth for demanding applications.

Cisco SG 550x

The Cisco 550X series is the newer generation of Cisco 500 switches.   This line of Switches is dedicated to deliver enhanced network performance, with advanced security capabilities. While the series carries some of the features from the older generation, it includes additional upgrades. These are responsible fir improved performance, including increased resiliency within the system and much more.


Cisco describes this collection as a next generation series of gadgets as they are manufactured with features to improve efficiency within operations. This series is great fir growing and demanding networks. The SG tag is designated to Cisco 550x models enabled with Gigabit Ethernet connectivity ports which are available in 24-48 number of ports.

Technically, the series is a Stackable Managed Ethernet Switch collection which combines software and hardware improvements to deliver advanced capabilities. For instance, the models adopt high performance 10GE connectivity. This encourages flexibility within growing business, with improved forwarding rates and overall better switching capacity performance.

True stackability unlike clustering ensures the Switches within the stack allow for configuration, management and troubleshooting over a unified platform. Moreover, the fact that you can mix stack these devices into one stackable unit makes for a very versatile network device. Stacking with these devices help reduce downtime and improve reliability and resiliency within the network operation. The external RPS system offers power redundancy in addition to the cooling fan redundancy provided.

Model designs on this collection include various power efficiency features and capabilities. For instance, the POE capabilities supported allow for simple and cost effective deployment. PoE+ support is available for powering these switches over Ethernet cabling.
