Some time ago I had a case with damaged file system on Huawei S5300 switch. It had been caused by power failure on one site. The switch was not able to decompress VRP software and rebooted itself all the time.

I decided to spend my vacation without access to internet, only wife, children, beach and windsurfing. I succeeded, September 3rd was the first day, after 3 weeks of my vacation, when I opened my mail box. Sorry for the delay in replying for your emails.
Last time I was asked about a procedure how to upload files through console port. The procedure is simple and I will try to show it in this post. Taking Huawei’s S3300 switch as an example I will show you how to upload file through console port, upgrading bootrom at the same time. Notice that uploading files by console is very slow and it is better to use it only for small files, unless you do not have any other choice.
Please use HyperTerminal to upload files by console port.
Power on the switch and enter into bootrom mode by pressing CTRL+B (default password huawei):

What to do if you forgot console password to Huawei S5300 switch?
I received such question last week. One of readers of this blog forgot console password and he wanted to modify startup configuration file from bootrom menu. His operation failed and there was a notification from the system that there is an “invalid package file!” and “auto-booting failed!”.
There was s5300ei-v100r002c02spc100 software installed in this switch so we can focus just on this software.
In S5300 there are two ways to solve this problem:
- Create configuration file on your PC, upload it to S5300 and modify startup file
- Delete configuration file from S5300 to let it to boot with empty configuration
Let’s start with the first way:
- Create configuration file on your PC. You can use default empty configuration downloaded from another switch
- Start FTP server on your PC
- Upload the configuration file to flash of S5300 from bootrom menu:
