請完成下列程序、視需要升級您的 Cumulus Linux 版本。

您需要的產品

中級Linux知識。
熟悉基本文字編輯、UNIX檔案權限及程序監控。已預先安裝多種文字編輯器、包括 vi 和 nano。
存取Linux或UNIX Shell。如果您執行的是Windows、請使用Linux環境做為命令列工具、與Cummulas Linux互動。
對於NVIDIA SN2100交換器主控台存取、序列主控台交換器上的傳輸速率需求設定為115200、如下所示：
- 115200傳輸率
- 8個資料位元
- 1停止位元
- 同位元檢查：無
- 流程控制：無

關於這項工作

請注意下列事項：

每次升級 Cumulus Linux 時、整個檔案系統結構都會被清除並重新建立。您現有的組態將會清除。更新 Cumulus Linux 之前、您必須先儲存並記錄交換器組態。

累計使用者帳戶的預設密碼為*累計*。第一次登入CummulUS Linux時、您必須變更此預設密碼。安裝新映像之前、您必須更新任何自動化指令碼。CummUS Linux提供命令列選項、可在安裝程序期間自動變更預設密碼。
