Henan Cisco agents Supply Cisco? Catalyst? 4900M Series Switches

Cisco Catalyst? 4900M series (Figure 1) is designed for data center network design of the widely deployed Cisco? Catalyst 4900 Series Advanced Extension top shelf Ethernet switches. Cisco Catalyst 4900M with high deployment flexibility to support uplink and downlink oversubscription ratio of 1: 1 10/100/1000 server access, as well as 10/100/1000 and 10 Gigabit Ethernet server combination, or a Gigabit Ethernet server environments. Cisco Catalyst 4900M is a 320Gbps, 250Mpps two racks (RU) fixed configuration switches, the basic unit provides 8 fixed wire-speed X2 ports, two optional expansion card slot can increase deployment flexibility and investment protection. Since the Cisco Catalyst 4900M low latency, with scalable buffer memory, high availability, and with 1 + 1 hot-swappable AC or DC power supplies and field-replaceable fan, making it suitable for all types of data centers. 10 Gigabit, Gigabit fiber and Gigabit copper and other flexible port configuration also serve as network aggregation layer switch, or the small size of the network core switches. Cisco Catalyst 4900M Gigabit Ethernet expansion cards and a variety of combinations of Gigabit Ethernet media types. Whatever the combination use, the base unit can be equipped with up to two expansion cards, by the following options: Figure 2.20 port wire-speed 10/100/1000 (RJ-45) port expansion card Figure 3.4 wire-speed Gigabit Ethernet net (X2) expansion card Figure 4.8 ports (2: 1) Gigabit Ethernet (X2) expansion card (compatible with Cisco TwinGig Converter Module) Except deployment flexibility, but also in the further expansion slot to add Gigabit Ethernet Investment protection when media networks and Gigabit Ethernet. Features and Benefits Cisco Catalyst 4900M as shown in Table 1. Table 1. Features and Benefits Feature Benefit superior scalability 16MB shared buffer using a large buffer for powerful, high-traffic control and 250Mpps up to 320Gbps wire-speed performance, low latency for delay-sensitive traffic forwarding, does not affect the normal operation of the line speed uplink expansion cards for use in any combination of switches, eliminate oversubscription bottlenecks uplink and downlink between. Select configuration flexibility Gigabit Ethernet and 10 Gigabit Ethernet interfaces migrate from Gigabit Ethernet to 10 Gigabit Ethernet configuration options provide fine-line insertion and removal of expansion cards service midline card replacement, hot-swappable support Cisco TwinGig Converter Module support on the same line card Gigabit Ethernet and 10 Gigabit Ethernet dual AC or DC power supplies for high availability, uninterrupted run investment protection through modular expansion slot to add expansion cards to migrate to the new media type line Cards can replace the power supply and hot-swappable fans to use existing software to extend the life of the hardware all Cisco Catalyst 4900 Series switches use the same mode of operation of a system, a variety of configurations Cisco Catalyst 4900M can be configured according to the needs of a variety of deployment. Various configuration options as shown in Table 2. Table 2. Cisco Catalyst 4900M 10 Gigabit Ethernet configuration options (X2) port 10/100/1000 Gigabit Ethernet port Cisco TwinGig converter modules (Small Form-Factor Pluggable [SFP]) port 10/100 / 1000 access, using Gigabit Ethernet uplinks 8400 10/100/1000 and 10 Gigabit Ethernet access, using Gigabit Ethernet uplinks or 16 200 12 Gigabit Ethernet (SFP) access using Gigabit Ethernet uplinks 8032 Gigabit Ethernet (SFP) and Gigabit Ethernet access, using Gigabit Ethernet uplinks or 16 016 12 Gigabit Ethernet access, use Gigabit Ethernet uplinks 16 or 2400 with the support of the same piece of expansion card Gigabit Ethernet and Gigabit Ethernet Cisco TwinGig converter module (Figure 5) can be a Gigabit Ethernet X2 interface into two Gigabit Ethernet port to use SFP optical module, enabling customers to use Gigabit Ethernet and Gigabit Ethernet X2 SFP optical module on the same card. Figure 5. Cisco TwinGig converter module can be a Gigabit Ethernet X2 interface into two Gigabit Ethernet SFP ports operational consistency and control of Cisco Catalyst 4900M contains management for all system features a control port. Remote in-band management via SNMP (SNMP), Telnet client, BOOTP and TFTP execution. If you want to support a local or remote-band management, you can use the console terminal or modem connected to the interface. Cisco Catalyst 4900M supports file allocation table (FAT) file system. System images can be updated directly via compact flash reader with a Windows machine. Use CiscoWorks solution, you can configure and manage, let Cisco Catalyst switches provide end device, VLAN, traffic and policy management. CiscoWorks LAN Management Solution (LMS) suite provides CiscoWorks Resource Manager Essentials (SNMS) and CiscoWorks CiscoView (SNMPS) and other tools. These Web-based management tools offer several services, including automated inventory collection information, software deployment, easy tracking of network changes, understand device availability, and quick isolation of errors. Support Cisco VFrame Data Center Cisco VFrame Data Center (DC) to Cisco Catalyst 4900 Series switches configured in Layer 2 topology. Based on the deployment mode automatically ask Cisco Catalyst 4900 Series switches use network can now offer through rapid deployment of Cisco VFrame Data Center. This important features supported include:? Cisco Catalyst 4900 Series switches and Layer 2 VLAN discovery and topology recognition create VLAN Membership Cisco EtherChannel port network interface card (NIC) portfolio allocation based on macro-port configuration Henan High St. Electronic Technology Co., The company is a private high-tech joint-stock enterprises, registered capital of five million yuan, is engaged in network products agents and distributors, integrated wiring, systems integration and application of technical services IT conglomerate.
