　　1、在所要查詢(xún)保修期或真?zhèn)蔚慕粨Q機(jī)上找到唯一序列號(hào)，并記下</p><p> 　　2、再打開(kāi)百度搜索引擎，輸入“華為企業(yè)產(chǎn)品”，進(jìn)行百度搜索，搜索結(jié)果中找到“華為企業(yè)產(chǎn)品技術(shù)支持網(wǎng)站”</p><p> 　　3、在新打開(kāi)的界面中找到“維保查詢(xún)”并點(diǎn)擊鏈接進(jìn)入</p><p> 　　4、輸入華為交換機(jī)上的序列號(hào)及驗(yàn)證碼，點(diǎn)擊查詢(xún)，如果產(chǎn)品是正品，在下面即可查詢(xún)出交換機(jī)的保修時(shí)間</p><h2>　　補(bǔ)充：交換機(jī)基本使用方法</h2><p> 　　作為基本核心交換機(jī)使用，連接多個(gè)有線設(shè)備使用：網(wǎng)絡(luò)結(jié)構(gòu)如下圖，基本連接參考上面的【方法/步驟1：基本連接方式】</p><p> 　　作為網(wǎng)絡(luò)隔離使用：對(duì)于一些功能好的交換機(jī)，可以通過(guò)模式選擇開(kāi)關(guān)選擇網(wǎng)絡(luò)隔離模式，實(shí)現(xiàn)網(wǎng)絡(luò)隔離的作用，可以只允許普通端口和UPlink端口通訊，普通端口之間是相互隔離不可以通訊的</p><p> 　　除了作為核心交換機(jī)(中心交換機(jī))使用，還可以作為擴(kuò)展交換機(jī)(接入交換機(jī))來(lái)擴(kuò)展網(wǎng)絡(luò)</p><p> 　　放在路由器上方，擴(kuò)展網(wǎng)絡(luò)供應(yīng)商的網(wǎng)絡(luò)線路(用于一條線路多個(gè)IP的網(wǎng)絡(luò))，連接之后不同的路由器用不同的IP連接至公網(wǎng)</p><h2>　　相關(guān)閱讀：交換機(jī)硬件故障常見(jiàn)問(wèn)題</h2><p> 　　電源故障：</p><p> 　　由于外部供電不穩(wěn)定，或者電源線路老化或者雷擊等原因?qū)е码娫磽p壞或者風(fēng)扇停止，從而不能正常工作。</p><p> 　　由于電源緣故而導(dǎo)致機(jī)內(nèi)其他部件損壞的事情也經(jīng)常發(fā)生。</p><p> 　　如果面板上的POWER指示燈是綠色的，就表示是正常的;如果該指示燈滅了，則說(shuō)明交換機(jī)沒(méi)有正常供電。</p><p> 　　這類(lèi)問(wèn)題很容易發(fā)現(xiàn)，也很容易解決，同時(shí)也是最容易預(yù)防的。</p><p> 　　針對(duì)這類(lèi)故障，首先應(yīng)該做好外部電源的供應(yīng)工作，一般通過(guò)引入獨(dú)立的電力線來(lái)提供獨(dú)立的電源，并添加穩(wěn)壓器來(lái)避免瞬間高壓或低壓現(xiàn)象。</p><p> 　　如果條件允許，可以添加UPS(不間斷電源)來(lái)保證交換機(jī)的正常供電，有的UPS提供穩(wěn)壓功能，而有的沒(méi)有，選擇時(shí)要注意。</p><p> 　　在機(jī)房?jī)?nèi)設(shè)置專(zhuān)業(yè)的避雷措施，來(lái)避免雷電對(duì)交換機(jī)的傷害?，F(xiàn)在有很多做避雷工程的專(zhuān)業(yè)公司，實(shí)施網(wǎng)絡(luò)布線時(shí)可以考慮。</p><hr /><p> 華為交換機(jī)怎么查詢(xún)真?zhèn)伪＜靶奁谙嚓P(guān)文章：</p><p>
