## Long description

The LevelOne KILBY 28-Port L3 Managed Gigabit Switch is a high-performance networking solution designed for demanding enterprise environments. It provides 24 Gigabit Ethernet ports for standard connectivity, complemented by two 10GbE SFP+ uplinks and an additional 10GbE module slot for high-speed data transfer. With its L3 routing capabilities and stackable architecture, this switch offers robust traffic management and scalability for growing network infrastructures.
Advantages
This managed switch excels in environments requiring high availability and advanced traffic control. Its stackable design allows for the integration of up to eight switches, simplifying management while increasing port density. The inclusion of 10GbE connectivity ensures that bandwidth-intensive applications and server aggregations operate without bottlenecks. Furthermore, the device supports comprehensive security features such as Dynamic ARP Inspection and Access Control Lists, ensuring that the network remains protected against unauthorized access and common spoofing attacks.
Suitable for
Enterprise data center server aggregation
Backbone network upgrades
High-performance Gigabit-to-the-desktop deployments
Network environments requiring advanced VLAN and QoS management
This switch may not be suitable for small home offices or basic residential setups where L3 routing and 10GbE uplink capabilities are not required. Its enterprise-grade feature set and rack-mount design are specifically optimized for professional IT environments rather than simple plug-and-play home networking.
Key specifications
24 x Gigabit Ethernet (10/100/1000) RJ-45 ports
2 x 10GbE SFP+ uplink ports
1 x 10GbE module expansion slot
Switching capacity: 128 Gbit/s
MAC address table: 16,000 entries
Managed L3 functionality with CLI/WEB support
Stackable architecture (up to 8 units)
Rack-mountable design
Weight: 3.7 kg
To use the LevelOne KILBY switch, mount it in a standard server rack and connect your network devices using appropriate Ethernet or fiber optic cables. Access the management interface via the RJ-45 console port or through the web-based GUI to configure VLANs, routing protocols, and security settings according to your network requirements. Ensure that the firmware is updated to the latest version to maintain optimal performance and security.
What to consider before purchase
Verify that your existing infrastructure supports the required SFP+ modules for 10GbE connectivity.
Ensure that your rack space is sufficient for the physical dimensions and weight of the unit.
Assess whether your network requires L3 routing features or if a simpler L2 switch would suffice.
Confirm that your power supply and cooling environment meet the requirements for enterprise-grade networking hardware.
Usage recommendations: For optimal performance in a stacked configuration, use high-quality cables and ensure all units are connected to a stable, uninterruptible power supply. Regularly monitor the switch via SNMP to proactively manage bandwidth and identify potential network bottlenecks.
