There are two main stacking connection methods: stacking card stacking and service port stacking. Stacking card stacking requires the purchase of dedicated stacking cards and stacking cables. Although this method is more expensive, it provides higher stability and transmission efficiency. Service port stacking, on the other hand, is more flexible, allowing users to use standard Ethernet cables or fiber optics for stacking. This method does not require additional hardware investment and is suitab

Power and data can be delivered simultaneously over Ethernet connections, thanks to a ground-breaking technology called Power over Ethernet (PoE). This approach greatly lowers expenses while streamlining network equipment installation and cabling. At the moment, IEEE 802.3af (PoE), IEEE 802.3at (PoE+), and IEEE 802.3bt (PoE++) are the three primary power supply specifications for PoE. Each standard represents a different set of application scenarios and power supply capabilities.

The Cisco Catalyst 9300 Series is a cutting-edge family of enterprise-class switches designed for scalability, flexibility, and security. A key feature of these switches is their stacking capability, which allows multiple units to function as a single logical device. The stacking feature enables seamless management and simplified network operations, often achieved using specialized stacking cables.
