2、對(duì)應(yīng)的指示燈熄滅.3. 如果端口自檢失敗如果端口自檢失敗, 對(duì)應(yīng)指示燈呈黃色對(duì)應(yīng)指示燈呈黃色.4. 如果有任何自檢失敗情況，系統(tǒng)指示燈呈現(xiàn)黃色如果有任何自檢失敗情況，系統(tǒng)指示燈呈現(xiàn)黃色.5. 如果沒(méi)有自檢失敗如果沒(méi)有自檢失敗, 自檢過(guò)程完成自檢過(guò)程完成.6. 隨著自檢過(guò)程的完成隨著自檢過(guò)程的完成, 指示燈閃亮后熄滅指示燈閃亮后熄滅.交換機(jī)初次啟動(dòng)時(shí)的顯示信息交換機(jī)初次啟動(dòng)時(shí)的顯示信息控制臺(tái)連接控制臺(tái)連接Catalyst 1900 Management ConsoleCopyright (c) Cisco Systems, Inc. 1993-1998All rights reserved.En
