The current image is s5000v5_ei-cmw710-boot-r6319p01.bin

(*)-with main attribute

(b)-with backup attribute

(*b)-with both main and backup attribute

//明显这个bin文件不是这个交换机的文件，交换机是旧的，忘记了配置，需要重新配置使用，找了运营商的工程师帮忙让调试一下，结果整成这样了，好像记得他往交换机里面ftp过文件，试了几次都没成，我这几天闲下来了，寻思着琢磨琢磨。

//如果键入5“恢复出厂配置”的话，显示：

Password recovery capability is enabled. To perform this operation, first

disable the password recovery capability using the undo password-recovery

enable command in CLI.

请各位大神指导。。。。。。。
