3 3COM SWITCH 4800G GIGABIT FAMILY KEY BENEFITS (continued) Powerful, Integrated Management Capabilities the Switch 4800G supports Simple network Management Protocol (SnMP) versions 1/2c/3 and open network management platforms such as OpenView and the QuidView network Management System (nMS). For additional convenience, the switches may also be managed via Command Line interface (CLi), Web network management, tELnEt and huawei Group Management Protocol (hGMP) cluster (stacking) management. Encryption modes such as SSh2.0, SnMPv3 and httPS are embedded in the switch, ensuring that management traffic is highly secure. MAC-and protocol-based VLAns, combined with ACL policies in the global or VLAn mode, minimize hardware resources and simplify configuration. inbound and outbound packets are randomly sampled and collected according to a set ratio with the sFlow function. LLDP and LLDP-MED are supported for standards-based neighbor discovery. Redundant Power System Support Four 3Com Switch 4800G models support a redundant power system (RPS) connection. RPS units provide these benefits: › For PWR switches, an RPS can deliver more power budget for iEEE 802.3af Power over Ethernet than what the switches alone can provide. › they deliver redundant power to switches so there is continued operation should the switch unit power supply fail. this allows for continuous operation of advanced Enterprise networks, particularly important for converged networks running iP phones on the network. 3Com H3C RPS Systems 3Com switches are compatible with 3Com h3C® RPS solutions. these are enterprise-class power redundancy systems that work with many 3Com fixed-configuration switches. 3Com Corporation manufactures networking equipment under the h3C brand for sale into many markets. these h3C RPS models are used with the Switch 4800G: › the h3C RPS 1000 is 1U high and provides multiple power output connections to support multiple switch units at the same time. two power rectifiers can be installed for 1+1 load sharing and power redundancy. it supports switches with -54V RPS connections, and delivers sufficient power to fully provision all PoE ports of a switch with full power redundancy. › the RPS 800 provides selective DC outputs of +12V and -54V. this is a fixed-configuration 1U high unit with a single power rectifier and a single power connection. Sufficient redundant power is available for provisioning a single Switch 4800G 48- or 24-port non-PoE unit. › the RPS 500 provides selective DC outputs of +12V and -54V. this is a fixed-configuration 1U high unit with a single power rectifier and a single power connection. Sufficient redundant power is available for provisioning a single Switch 4800G 24-port non-PoE unit. FEATURE HIGHLIGHTS Provides up to 450 Gigabit ports in a stack nine units high, managed as a single-iP entity Equipped with four dual-purpose ports providing either 10/100/1000 or SFP Fast/Gigabit Ethernet connectivity Full iPv4/iPv6 networking support Offers optional 2-port 10-Gigabit (XFP or SFP+), 2-port local connection, or 2-port Fast Ethernet (SFP) modules Delivers wirespeed and line-rate performance on all ports Offers OSPF and multicast routing, 3Com XRn stacking technology and iEEE 802.3af Power over Ethernet Provides high resiliency and continuous availability with active load sharing and support for ultra-fast failover recovery implements multilayer distributed security including ACLs, DES 56/168-bit† encryption, iEEE 802.1X network login and RADA authentication Prioritizes converged network traffic to ensure high levels of service for latency-sensitive applications Supports advanced enterprise switching technology: Border Gateway Protocol (BGP), VLAn VPn (Q-in-Q) and others Leverages existing infrastructure power schemes with built-in support for both AC and DC power Consolidates administrative control and enhances core-to-edge visibility with the latest Comware V5 OS Offers an SFP-based model with 24 SFP Gigabit ports, eight of which are dual-purpose Backed by top-flight service, support and training from 3Com and 3Com authorized partners † 168-bit encryption not available in all countries.
