- 強(qiáng)化 PoE + 供電覆蓋能力：若設(shè)備延續(xù) PoE + 特性，單端口最大輸出 30W，總 PoE 功率預(yù)計達(dá) 370W-500W，可同時為 48 臺 PoE 終端供電（實(shí)際數(shù)量需結(jié)合設(shè)備功耗，如攝像頭約 15W / 臺、AP 約 20W / 臺），無需額外部署多臺 PoE 注入器或交換機(jī)，尤其適配大型監(jiān)控系統(tǒng)、無線覆蓋密集的場景，簡化布線的同時降低供電成本。
- 專業(yè)托管型管理升級：繼承 Web 圖形化界面與 CLI 命令行操作，新增 “端口分組管理” 功能，可按部門、區(qū)域?qū)?48 個電口分組配置 VLAN、QoS 策略，避免單端口逐一設(shè)置的繁瑣；支持 SNMP v3 協(xié)議與 Enterasys OneControl 平臺深度對接，可同時監(jiān)控多臺 48 口交換機(jī)的端口狀態(tài)、流量分布，批量下發(fā)配置模板，大幅提升大規(guī)模網(wǎng)絡(luò)的運(yùn)維效率。
- 多層級可靠性保障強(qiáng)化：除 STP/RSTP/MSTP 生成樹與 LACP 鏈路聚合外，新增 “端口冗余備份” 功能，可將空閑電口設(shè)置為關(guān)鍵終端（如服務(wù)器、核心攝像頭）的備用端口，故障時自動切換；同時優(yōu)化風(fēng)暴抑制算法，支持基于端口的廣播 / 組播 / 單播風(fēng)暴閾值自定義，精準(zhǔn)攔截不同區(qū)域的異常流量，防止大規(guī)模網(wǎng)絡(luò)因局部故障癱瘓。
Extreme Networks 08G20G4-48P以太網(wǎng)交換機(jī) 英文資料：
48 port full gigabit high-density access architecture: As an upgraded version of the 08G20G4-24P port, the 08G20G4-48P provides 48 10/100/1000Base-T electrical ports, paired with 4 SFP gigabit optical ports, doubling the number of electrical ports. It can simultaneously access 48 terminal devices (such as PCs, IP phones, high-definition cameras), covering high-density scenarios such as medium-sized enterprise office areas, large chain stores, and small data center access layers with a single device. Compared with 2 24 port switches, it reduces cabinet space occupation by 50% and reduces management complexity caused by device stacking.
Doubling performance to support large-scale business: the entire machine's switching capacity has been increased to 96Gbps, with a packet forwarding rate of 71.4Mbps, supporting full gigabit non blocking transmission, and able to stably carry large-scale business such as multi department concurrent office work, more than 32 4K monitoring feedback channels, and multiple video conferences, avoiding performance bottlenecks caused by port expansion; Simultaneously optimizing the data caching mechanism, the single port cache capacity has been increased to 2MB, which can cope with sudden traffic shocks, reduce data packet loss during peak hours, and ensure business smoothness.
Strengthening PoE+power coverage capability: If the device continues the PoE+feature, the maximum output of a single port is 30W, and the total PoE power is expected to reach 370W-500W, which can simultaneously power 48 PoE terminals (the actual number needs to be combined with device power consumption, such as cameras about 15W/unit and APs about 20W/unit), without the need to deploy multiple PoE injectors or switches, especially suitable for large monitoring systems and wireless coverage intensive scenarios, simplifying wiring while reducing power supply costs.
Professional hosted management upgrade: Inheriting the Web graphical interface and CLI command line operation, adding the "Port Group Management" function, which can group 48 electrical ports by department and region to configure VLAN and QoS policies, avoiding the tedious process of setting up a single port one by one; Support deep integration between SNMP v3 protocol and Enterasys OneControl platform, which can simultaneously monitor the port status and traffic distribution of multiple 48 port switches, issue configuration templates in batches, and greatly improve the operational efficiency of large-scale networks.
Multi level reliability assurance enhancement: In addition to STP/RSTP/MSTP spanning tree and LACP link aggregation, a "port redundancy backup" function has been added, which can set idle electrical ports as backup ports for critical terminals (such as servers and core cameras) and automatically switch in case of failure; Simultaneously optimize the storm suppression algorithm, support port based broadcast/multicast/unicast storm threshold customization, accurately intercept abnormal traffic in different regions, and prevent large-scale networks from being paralyzed due to local failures.
