WS-C4507R引擎故障更換

最近在一用戶處巡檢，發(fā)現(xiàn)其核心交換機cisco4507R一個引擎有報警，查看module情況如下：

在槽2 的引擎板看不到，冗余狀態(tài)為disable，判斷引擎板有問題，因這個型號太老了，只能買到一塊舊的引擎板，為保險起見，更換引擎前先備份配置和運行引擎板的ios，因怕ios太大tftp 32M文件的限制，采用ftp來上傳，用win7自帶的ftp功能（win7怎么配ftp可以百度一下），具體過程如下：

4507r(config)#ip ftp username czq

4507r(config)#ip ftp password 615

在4507上建立可以ftp的win7 ftp服務器的用戶名和密碼，接下來備份ios，

4507r#copy bootflash:cat4500-ipbase-mz.122-31.SGA8.bin ftp

Address or name of remote host []? 192.168.13.107

Destination filename [cat4500-ipbase-mz.122-31.SGA8.bin]?

Writing cat4500-ipbase-mz.122-31.SGA8.bin !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!12127880 bytes copied in 12.096 secs (1002636 bytes/sec)

同樣把start-config配置也拷貝一下。

 把引擎板熱插入原故障板的槽位中，耐心等待直到原故障燈變?yōu)榫G色，查看module，發(fā)現(xiàn)更換的引擎與原引擎版本不同，并且冗余狀態(tài)為 Standby Supervisor SSO Standby clod，這不是想要的最終狀態(tài)，需要升級引擎與原引擎一致，過程如下：

4507r# copy bootflash： slavebootflash：

刪除slave的ios ：

4507r#delete slavebootflash：

需要把更換的引擎板再重啟一下，（可以重新插入引擎板），以便新ios生效，最后module狀態(tài)如下：

 4507r#show module

現(xiàn)在更換引擎已是熱備狀態(tài)，齊活，可以收工了。
