This document describes the Cisco 500 Series Stackable Managed Switches, a line of network communication devices designed for small and medium-sized businesses. These switches are engineered to be operational right out of the box, functioning as standard Layer 2 and Layer 3 switches that forward packets between connected devices upon power-up.
The Cisco 500 Series switches offer robust functionality for network connectivity and management. They are designed to be deployed in various network environments, providing a flexible solution for connecting computers, printers, network storage, and other network devices. A key feature of these switches is their stackable nature, allowing multiple units to be combined into a single logical unit, which simplifies management and increases network capacity and resilience.
The primary function of the Cisco 500 Series switches is to facilitate network communication by forwarding data packets. They operate at both Layer 2 (data link layer) and Layer 3 (network layer) of the OSI model, enabling them to handle both local network traffic and routing functions. In their factory default configuration, they are ready to forward packets immediately after being powered on, making initial setup straightforward.
These switches support Power over Ethernet (PoE) on specific models, allowing them to supply DC power to attached Powered Devices (PDs) such as VoIP phones, IP cameras, and wireless access points over the same Ethernet cable that carries data. This eliminates the need for separate power outlets for these devices, simplifying deployment and reducing cabling complexity. The PoE models are capable of detecting and supplying power to both pre-standard and standard PoE Powered Devices. However, users are cautioned to disable PoE on ports connected to other Power Sourcing Equipment (PSEs) to prevent false detection and potential operational issues.
The stacking capability is a significant feature, allowing up to eight 500 Series switches to be connected together to form a single, high-performance stack. This provides increased port density, aggregated bandwidth, and simplified management as the entire stack can be managed as a single entity. The switches support different stack unit modes:
The stack ports can be configured with various speeds (1G, 5G, 10G, or auto-detection) depending on the switch model and stacking option chosen. It is crucial that stack ports are configured with the same port speed or have compatible speed capabilities on the modules/cables to ensure proper stack formation.
The Cisco 500 Series switches are designed for ease of use and flexible deployment. They can be placed on a flat surface or mounted in a standard 1-rack unit (1RU) rack. When rack-mounting, it's important to ensure proper airflow and avoid mechanical or circuit overloading. The package includes a rackmount kit, power cord, serial cable, and rubber feet for various installation scenarios.
Connecting network devices is straightforward:
Management of the switch can be done through two primary methods:
The front panel of the switch features various LEDs that provide visual status indicators:
The Cisco 500 Series switches include features to aid in maintenance and troubleshooting.
copy running-config startup-config is used to save changes.The switches support SFP (small form-factor pluggable) and SFP+ modules, which are connection points for linking to other switches. These ports are also known as miniGigaBit Interface Converter (miniGBIC) ports. The SFP ports are compatible with various Cisco and other brand modules, while SFP+ optical modules are supported in 500X switches for higher-speed connections. SFP interfaces are combination ports, sharing functionality with an adjacent RJ-45 port; when the SFP is active, the RJ-45 port is disabled.
The Cisco 500 Series Stackable Managed Switches are designed to be a reliable and scalable solution for network infrastructure, offering a balance of performance, flexibility, and ease of management for growing businesses.
