Описание
Cisco EHWIC-D-8ESG-P is the 8 ports POE high-speed Gigabit Ethernet interface module for 1900/2900/3900 series ISR2 router. The low-density Gigabit Ethernet interface switching module designs for small to medium-size business or branch offices to reduce the total cost of ownership and simplified management by integrating switching and routing functionality into a single chassis. Moreover, the switching module enables Cisco's industry-leading power initiatives, Cisco EnergyWise, Cisco Enhanced Power over Ethernet (ePoE), and per-port Power over Ethernet (PoE) power monitoring, which enhance the ability of the branch office to scale to higher performance requirements and still meet environmental initiatives for IT teams to operate a power-efficient network.
