求助！关于使用xmodem传输ios的问题

laqbbb

我误删除了思科2960s系列交换机的flash，上网搜索知道要使用xmodem传输ios到设备中再boot，可是每一次ios文件都传送失败，显示如下：
switch: copy xmodem: flash:c2960-lanbasek9-mz.122-55.SE7.bin
Begin the Xmodem or Xmodem-1K transfer now...

switch: dir flash:
Directory of flash:/


32513024 bytes available (1024 bytes used)



这个ios文件是从另一台正常设备上复制下来的，请问是哪里的问题？

之前使用的xshell，换成超级终端就好了。。。
