高速、高備援10G脊葉(Spine-Leaf)網路

M4300-28G全網管交換器是市面首創的堆疊式交換器，擁有24個1G RJ45 + 2個10G RJ45 + 2個SFP+網路埠口，讓中小企業可輕鬆建置高備援的小型骨幹網路或小型IP SAN網路，例如 : 光纖連接到需要高速頻寬的網路儲存，或使用RJ45線路連接多台伺服器，如此一來便可降低伺服器10G網路卡的採購成本。只需使用一台交換器即可同時收納10G的光纖與RJ45連線，大量降低成本，並帶來速度升級的優勢。
M4300系列搭載原本應用在Chassis交換器中的Spine-Leaf技術，混合Trunking、Redundant、Stacking等應用，可輕易的建置高備援的網路環境。不用再擔心線路斷線的問題。
