NMC 是一種介于UPS和網(wǎng)絡的設備，它可以從UPS獲得狀態(tài)信息并且發(fā)出指令。NMC支持兩種協(xié)議－簡易網(wǎng)絡管理協(xié)議(SNMP)和超文件傳輸協(xié)議(HTTP)以供使用者進入。通過SNMP的網(wǎng)絡管理站(NMS)和網(wǎng)頁瀏覽器，用戶可以獲得UPS的狀態(tài)信息、發(fā)出指令至UPS并且通過網(wǎng)絡設定NMC。
NMC 也為不同的操作系統(tǒng)提供關機軟件。不同操作系統(tǒng)的關機軟件可以通過網(wǎng)絡連接至NMC，并且利用特殊的通信方式與NMC卡通訊。當UPS發(fā)生異常以及用戶設置的條件滿足時，NMC會發(fā)出關機消息至裝有關機軟件的客戶端。關機軟件根據(jù)自身的設定進行對應的關機的程序，從而避免因電力問題而造成客戶端和服務器的不正常關機。
