A cup with a power failure that causes the Huawei switch to fail to start

The previous day, a power failure caused a switch in the branch to fail to start.

Fault description: The day before yesterday, our branch colleagues called us and said they were connected to the organization. I went through the ping test and found that the gateway to the branch was successful, but I couldn't reach the branch server.

The preliminary judgment is whether the network cable between the switch or the switch and the router has been broken (the network environment of the Branch is not very good, and there may be animals like rats ).

Later, the startup file of the flash switch of the System Branch was damaged.

Recovery Process: Huawei quidway s3500c Switch

Since this switch is an old one and the unit has other same vswitches, it is decided to import the Startup File from other vswitches and then reconfigure the vswitch.

1. Download the tftp software from the Internet and install it on the local machine;

On the basis of the local machine, enter the normal switch

<Xxxx_3528c> dir Enter

# List files in flash of a vswitch;

Directory of flash :/

-Rwxrwxrwx 1 wl_qjx 4115639 Sep 17 2005 11:23:08 S3528efc-vrp310-r0030.bin

......

<Xxxx_3528c> sys Enter

[Xxxx_3528c] tftp put S3528efc-vrp310-r0030.bin // 17.01.88

#172.161.88 is the server address, that is, the address where the tftp software is installed on the local machine;

# Store the BIND file in the normal switch to the server in the System View;

2. Import the BIND file to the flash of the broken switch.

Log on to the damaged switch through the Super Terminal on the local machine, and delete the damaged binfile step by step according to the boot menu.

Then press 1 in the boot menu to download the binfile. At the same time, because I didn't know how to configure the switch, I used XMODERM to download the binfile.

Note: In Please select your download baudrate, it must be consistent with the bit rate set by yourself.

Because my Super Terminal bit rate is 9600, I chose 1. At the same time, select the send button under the menu to display the Send File window, select the bin you just downloaded from the normal switch, and select XMODERM here for the Protocol, send the file to the vswitch as prompted.

Transferring files via XMODERM is a little slow. Please wait, but this is also the safest.

3. Restore the vswitch Configuration

Re-configure the switch through the transferred configuration file.
