SUPERSTACK 3 SWITCH 4400 PWR ML (NMS)
In-line Power over Ethernet Switch with 24 10/100 Ports
The SuperStack® 3 Switch 4400 PWR combines Power over Ethernet technology (IEEE-802.3af) with the advanced features, simplicity, and style of the SuperStack 3 Switch 4400 family.
The compact stackable 1-RU design provides power and data over a single cable to any compliant device, including 3Com NBX phones, wireless LAN access points, Network Jack, and IntelliJack™ products.
Power over Ethernet eliminates additional electrical cabling costs and greatly reduces total installation time and expense, helping to lower the total cost of ownership, especially when paired with networked telephony solutions.
The switch supports all SuperStack 3 Switch 4400 enhanced capabilities, such as traffic classification and prioritization, traffic filtering, and IEEE 802.1X network log-in for user-based security.
The Switch 4400 PWR can stack with other enhanced SuperStack 3 Switch 4400 devices to form a resilient switch stack of up to 384 10/100 ports. This allows distribution of high-speed connections across the stack (up to 4Gbps) for resilient, high capacity connections to the network core, including those running with 3Com XRN™ technology.
Optional switching modules provide resilient high-speed connections such as Fast Ethernet, including 100BASE-LX (Ethernet in the First Mile), and Gigabit Ethernet copper or fiber links.
Data switching and Power over Ethernet (PoE) integrated into one unit, saves rack space, excess cabling, and the need for multiple backup systems— simplifying installation of networking devices
Complies with the IEEE 802.3af specification
Shares the enhanced switching feature sets of the SuperStack 3 Switch 4400 family, including advanced Layer 4 traffic classification and prioritization, and RADIUS security network login and accounting
User network login with IEEE 802.1X and RADIUS, combined with RADIUS Authenticated Device Access (RADA), based on MAC address, provide secure network access control at the network edge
Authenticated users can be automatically placed into a specific VLAN, restricting access only to the data needed
Secure Shell (SSH) encryption of login passwords, management VLANs, and management station "trusted IP address" lists help protect network from rogue management threats
Add optional switching modules to provide resilient high-speed connections, such as Gigabit Ethernet backbone links, or 100BASE-LX 10 links for Ethernet in First Mile over Point to Point Fiber (EFMF)
Ideal solution for NBX voice telephony installations, as switch automatically prioritizes NBX voice traffic; guaranteed power support for up to 24 NBX phones per switch
Pre-configured PoE power profiles for 3Com equipment eases power budgeting; use with networked phones and 3Com Network Jacks and IntelliJack™ products and enterprise LAN access points
Mix and match 24-port and 48-port SuperStack 3 Switch 4400s to create a resilient stack of up to a total of 384 10/100 connections
Redundant power for all stacked units using the 3Com SuperStack Advanced Redundant Power System
3Com Network Supervisor software (60-day trial included) supports automatic prioritization of real-time or critical traffic
