The 16-port 10 Gigabit Ethernet module provides up to 130 10 Gigabit Ethernet ports in a single Cisco Catalyst 6500 chassis and 260 10 Gigabit Ethernet ports in a virtual switching system (VSS) and is targeted for LAN campus aggregation and data center access, where fan-out and port density are very important. It consists of 4 port groups of 4 ports each. Users can operate each port group in either oversubscription mode (2 to 4 ports used per port group) or performance mode (1 port used per port group), allowing maximum flexibility for using some ports for connection to servers in performance mode and some other uplinks to wiring closets in oversubscription mode. When in performance mode, up to four 10 Gigabit Ethernet ports can be used to create a virtual switch link in a VSS.1 In addition, the 16-port 10 Gigabit Ethernet module has reduced power consumption. It uses half the power per port compared to the 8-port 10 Gigabit Ethernet module, providing substantial power savings to the customer.
CloudEngine S5731-H series switches are brand-new enhanced gigabit access switches that provide all-GE electrical downlink ports, fixed 10GE uplink ports, and one extended slot. CloudEngine S5731-H delivers gigabit connectivity at the aggregation or access layer in large and midsize campuses, at the core layer in branches and small campuses, and at the access layer in data centers. Integrating native WLAN AC capabilities to support up to 1024 WLAN APs, CloudEngine S5731-H enables you to converge your wired and wireless networks for simplified operations. It also offers free mobility to deliver consistent user experience and VXLAN-based virtualization to create a multi-purpose network. With built-in security probes, CloudEngine S5731-H supports abnormal traffic detection, Encrypted Communications Analytics (ECA), and network-wide threat deception.
HUAXUAN HIGH TECHNOLOGY�® KH-204 Is a new version high-performance polycarboxylic superplasticizer. Compared with other high efficiency water-reducing agents,it has the properties of ultra-high water reduction,low shrinkage,low bleeding rate and small avalanche loss. Ultra-high water reducing rate:up to 40%,particularly significant in high-grade concrete (above C50).In the same condition,it costs less material to get the same effect. Excellent plastic retention: Excellent plastic retention performance: Because the steric hindrance of the extended polymer side chain effectively hinders the secondary agglomeration between cement particles, the product has high dispersion and can maintain this performance for a long time. Good early strength and strengthening effect: under the same conditions, the concrete mixed with this product has a higher early strength and strengthening effect than other types of superplasticizers. Significantly improve the durability of concrete: The product has a low alkali content, and because itâ??s an air-entraining type high efficiency water reducing agent, it significantly reduces the alkali-aggregate reaction of concrete and improves the freeze-thaw resistance of concrete. Stability: The concrete shrinkage and creep properties will be effectively improved after adding the product,in the meanwhile, it gains a good stability, so there are lower risks of cracks.
