Key Features:

• Cost-effective 10/100 Layer 2 Ethernet switch provides 24 or 48 10BASE-T/100BASE-TX autosensing ports, 2 flexible combo uplink ports, and built-in stacking ports that reduce cost by eliminating the need to purchase cascade modules.
• A scalable, stackable architecture enables up to 8 switches to be connected to support up to 384 ports.
• Two flexible combo uplink ports for high-speed connectivity to wiring closet or backbone devices.
• Wire-speed performance is delivered by a 16 Gigabit per second (Gbps) switch fabric that supports full frame forwarding and filtering across all ports at wirespeed performance.
• BoSS (Ethernet Switch Software) is a single software image that is used for Ethernet Switches 425-24T, 420-24T, and 425-48T. Future versions provide new features and will be available for free for the lifetime of the switches.

Features & Benefits

Cost-effective 10/100 Layer 2 Ethernet switch provides 24 or 48 10BASE-T/100BASE-TX autosensing ports, 2 flexible combo uplink ports, and built-in stacking ports that reduce cost by eliminating the need to purchase cascade modules.

• A scalable, stackable architecture enables up to 8 switches to be connected with Gigabit cable to support up to 384 ports.**
  
• Two flexible combo uplink ports for high-speed connectivity to wiring closet or backbone devices.
  
• Wire-speed performance is delivered by a 16 Gigabit per second (Gbps) switching fabric and ASICs that filter and forward up to 6.6 million packets per second with no packet loss.
  
• BoSS (Ethernet Switch Software) is a single software image that is used for Ethernet Switches 425-24T, 420-24T, and 425-48T.
  
• Distributed Multi-Link Trunking (DMLT) feature allows trunked ports to span multiple units of the stack for redundant connectivity to mission-critical servers and the network center.
  
• Up to 255 port-based VLANs can be established for each switch, to extend the broadcast domain and segment network traffic for higher network efficiency.
  
• Support for up to 8,000 MAC addresses provides scalability for growing networks with many attached devices and workgroups connected to each switch.
  
• User Interface push-button on the front panel is provided for the purpose of base unit selection and, for resetting the unit or the stack.
  
• Auto MDI/MDI-X feature on each port allow the use of either a crossover or straight through cable to connect to a hub or switch
  
• IEEE 802.1p queuing prioritizes the order in which the switch forwards packets. The switch supports up to four queues.

Benefits

• Scale easily as the network grows, by stacking up to 8 units and 384 ports. Built-in stacking connectors make stacking very easy and save money by not requiring additional cascade module.
  
• Deliver wire-speed throughput, up to 10.1 million packets per second with no packet loss.
  
• Resilient uplink connectivity for minimal network downtime.
  
• Simple software upgrades with single image for Ethernet 425 and 420 Switches.
  
• Common look and feel across Ethernet Switches minimizes training and installation costs.
  
• Power and space savings with a low power consumption of 46W and 1 rack-unit high design that saves premium wiring closet space.
