How To

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:

1. Create configuration file on your PC, upload it to S5300 and modify startup file
2. 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:

In my previous post I wrote about upgrade of Huawei S5300 switch. The question is, what to do if flash memory is too small to fit more than one software. As it was mentioned last time, you can format flash from bootrom menu and download a new software using FTP, from bootrom menu. In this post I will show you how to deal with this problem more smoothly. You can come up against this problem in Huawei S3328TP-SI switch, where flash capacity is 15MB. Let’s take it as an example.

<S3328>display version

Quidway S3328TP-SI uptime is 0 day, 0 hour, 4 minutes

As you can see flash capacity is 15MB:
