Product Features
Technical Overview
This Cisco switch operates as a fully manageable Layer 2 device, providing advanced networking features such as IGMP snooping for efficient multicast traffic handling, port mirroring for network monitoring and troubleshooting, and spanning tree protocols for loop prevention and network redundancy. The eight RJ-45 ports deliver Gigabit Ethernet speeds and support PoE+ (IEEE 802.3at), allowing simultaneous data and power delivery over standard twisted-pair cabling.
The dual SFP expansion slots offer modular flexibility, supporting either fiber optic SFP modules for distances up to kilometers or copper SFP modules for shorter runs. Switching capacity is optimized for Gigabit throughput across all ports, with non-blocking architecture ensuring full wire-speed performance. Management is accessible via a web-based interface or command-line interface (CLI), giving administrators granular control over VLANs, QoS, security policies, and port configurations.
This section brings together practical product details such as Total Number of Network Ports, Uplink Port, Modular, Media Type Supported, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.

Deployment / Use Cases
This switch is ideal for environments where reliable, managed connectivity and PoE+ power are required in a centralized rack location. Small office networks benefit from its eight ports for connecting workstations, printers, and PoE devices, while the management features allow for secure segmentation of guest or departmental traffic.
In retail or hospitality settings, it can power and connect VoIP phones, wireless access points for guest Wi-Fi, and IP cameras for security, all through a single switch. The SFP slots enable fiber uplinks to a core switch or router in another building, making it suitable for distributed sites or campuses needing extended reach beyond copper limitations. IT managers appreciate the refurbished condition for cost-effective network upgrades without sacrificing Cisco reliability or feature sets.
Physical Profile
The switch features a steel chassis with a 1U rack-mountable form factor, measuring 1.73 inches in height, 10.56 inches in width, and 7.28 inches in depth. Its compact design fits standard 19-inch rack cabinets, with included mounting brackets for easy installation. The front panel houses all eight RJ-45 ports, two SFP slots, and LED indicators for power, link activity, and PoE status. Rear-panel connections include a power inlet and grounding point, with ventilation for passive cooling. The robust construction ensures durability in controlled environments like wiring closets or server rooms.

User Manual
FAQ
How many devices can this switch power with PoE+?
The switch has a total PoE budget of 67W across its eight PoE+ ports. Each port can deliver up to 25.5W, so the number of devices depends on their individual power requirements. For example, it could power several VoIP phones (typically 3-7W each) and multiple wireless access points (15-20W each) simultaneously, as long as the total does not exceed 67W. The switch automatically negotiates power delivery per port.
What are the SFP slots used for?
The two SFP (Small Form-factor Pluggable) slots allow you to add fiber optic or copper uplink modules for network expansion. You can use them to connect to another switch or router over longer distances via fiber (e.g., up to several kilometers with appropriate SFP modules) or for high-speed copper links. They are shared slots, meaning they can be used interchangeably based on your network topology needs.
Is this switch manageable, and what features does it support?
Yes, this is a fully manageable Layer 2 switch. It supports features like VLANs for network segmentation, Quality of Service (QoS) for prioritizing traffic, port security to control device access, IGMP snooping for efficient multicast streaming, and port mirroring for monitoring. Management can be done through a web-based graphical interface or a command-line interface (CLI), offering flexibility for different IT skill levels.
What does 'refurbished' mean for this Cisco switch?
Refurbished indicates the switch has been previously used or returned, then professionally inspected, tested, and restored to full working condition. It undergoes cleaning, component checks, and firmware updates to meet original performance standards. Refurbished products often come with a warranty and offer a cost-effective alternative to new hardware while maintaining reliability and compatibility with Cisco ecosystems.
Can this switch be mounted in a rack?
Yes, the switch is designed for rack mounting with a standard 1U height. It includes mounting brackets (ears) that attach to the sides for installation in a 19-inch rack cabinet. The compact dimensions—1.73" H x 10.56" W x 7.28" D—make it suitable for space-constrained environments like data closets or server rooms, and it supports front-to-back airflow for proper cooling in enclosed racks.
What types of cables and media does this switch support?
The switch supports twisted-pair copper cables (Cat5e/Cat6/Cat6a) for its eight RJ-45 ports, which are used for Gigabit Ethernet connections up to 100 meters. For the SFP slots, it supports optical fiber cables (via SFP modules) for longer-distance links or copper SFP modules for shorter runs. This dual-media flexibility allows integration into diverse network infrastructures, from office LANs to fiber-based backbones.
What uplink, SFP, fiber, or media support detail is listed?
The warranty or support detail listed is Yes, giving buyers a clearer picture of expected coverage after purchase.
Does the product support PoE or wireless networking?
Connectivity support is listed in the product specifications, including the relevant wireless or port options when available.
