PBSSF-M50 --10G/1G独立式多模光口断电型Bypass设备
-
产品概述
Silicom PBSST是一款外置bypass断电保护设备,应用于10G/1G光纤以太网络。该设备通过确保断电时的网络完整性来防止网络故障或网络维护时数据中断,它包括Network端口、Monitor端口和Control端口,Network端口用于连接左右两端的交换机/路由器,Monitor端口用于连接被保护的网络设备,Control端口用于控制PBSST的工作模式。通电时,PBSST的工作模式设置为正常,断电时PBSST的工作模式设置为旁路。
- 功能概述
在正常模式下,PBSST将数据从Network端口转移到Monitor端口。
