xStack DGS-3120系列 L2 網管型Gigabit交換器
44埠10/100/1000Base-T + 4埠Combo 10/100/1000Base-T/SFP + 兩埠實體堆疊埠。
DGS-3120-48TC為xStack系列最新一代L2 Gigabt交換器機種。支援D-Link Grenn節能技術,領先業界於網管型交換器導入節能機制,可偵測線路長度及遠端電腦開關機狀態自動調整電力輸出。提供完整的E2ES安全性功能及支援完整的IPv6功能,可提供客戶具備未來相容性、擴充性及安全應用的需求。
DGS-3120系列提供豐富的Endpoint Security機制:
• Host-based 802.1X認證/授權
• DHCP Server Screening
• 支援Microsoft 802.1X/ DHCP NAP
• 整合D-Link Zone Defense區域聯防機制
DGS-3120-48TC支援D-Link Green節能技術
1. 自動偵測網路線長度: 傳統交換器連接埠電力輸出可將訊號傳輸至100公尺。
但多數辦公網路環境連接電腦距離多在50公尺之內,
將會依據網路線長度自動調節電力輸出在不影響傳輸效能狀況下節省交換器電力需求。
2. 自動偵測電腦開關機: 自動偵測遠端設備開關機狀態,電腦關機時該連接埠自動調整呈休眠狀態,大幅節省電。
通過IPv6 Ready Logo Phase2認證,支援IPv6功能。
