The official source for downloading Huawei switch firmware is the Huawei Enterprise Support Portal
. To access these files, you generally need an enterprise account with the appropriate permissions. Review: Huawei Switch Firmware Upgrade Process
Upgrading a Huawei switch is a critical but well-documented procedure. The process varies depending on whether you use the Command Line Interface (CLI) Web-based management Smart Upgrade 1. Preparation & Accessibility Account Requirements
: Accessing firmware requires an enterprise login. Users often find this restrictive, as a standard personal account (like Gmail) usually lacks the necessary download privileges. File Verification : Huawei provides system software ( ) and patch files (
). A strong point in their process is the emphasis on integrity; users are encouraged to verify files using CRC checks before proceeding. Documentation
: Each version typically comes with a specific upgrade guide, which is highly detailed and helpful for navigating version-specific dependencies. 2. Upgrade Methods
Upgrading firmware on a Huawei switch can be done through several methods, each suited for different environments. Below are the most common approaches, with direct links to the official Huawei support documentation for each. 1. The Standard Manual Upgrade (CLI or Web)
For most network administrators, the standard manual process involves downloading the firmware file (usually with a .cc extension) and a patch file (.pat) from the Huawei Enterprise Support Portal.
Download Source: Log in to Huawei Support and search for your specific model (e.g., S5700 series) under the Software Download tab. The Process: huawei switch firmware upgrade link
Transfer the files: Use FTP or SCP to upload the new firmware to the switch's flash memory.
Configure next startup: Use the command startup system-software to tell the switch which file to use when it reboots.
Verify & Reboot: Check the configuration with display startup, then perform a reboot to complete the process. 2. The One-Click "Smart Upgrade"
If your switches have internet access, Huawei offers a more automated "Smart Upgrade" feature through the Huawei Online Upgrade Platform (HOUP).
Huawei switch firmware and patches can be downloaded directly from the official Huawei Enterprise Support Portal
. Accessing these files typically requires an enterprise or partner account; a standard guest account may have restricted download permissions. How to Find and Download Firmware
To find the correct firmware version for your specific device, follow these steps: Locate Your Model : Log in to the Huawei Support Site and navigate to Support > Software Download Select Product Series Enterprise Network > Switches , then select your specific series (e.g., S5700 Series Identify Versions
: Look for the target software version, usually formatted as VxxxRxxxCxx V200R019C10 Download Files System Software : The main image file ends in Patch Files : These fix specific bugs and end in Documentation : Always download the Upgrade Guide Release Notes The official source for downloading Huawei switch firmware
corresponding to your version to check for hardware compatibility and dependencies. Summary of Common Upgrade Commands
Once you have uploaded the files (via FTP, TFTP, or SCP) to the switch's flash memory, use these CLI commands to execute the upgrade: CLI Command Check Current Version display version Specify Software for Startup startup system-software

At 3:47 AM, the standby module rebooted successfully. Lin Wei initiated a failover test. Traffic shifted seamlessly. Then, the active module—now idle—began emitting a faint, high-pitched whine from its power supply. He touched the chassis. Hot. Too hot.
He checked the sensors: Temp: 82°C (critical threshold 85°C).
The firmware upgrade had changed the fan PWM algorithm. The new default curve was too conservative. Without a config adjustment, the switch would overheat in 12 minutes.
Lin Wei opened the hidden enhanced thermal profile link (another URL he’d saved from a forgotten Huawei forum thread):

There, a field engineer from Brazil had posted a fix: a single line of CLI to override the fan duty cycle.
He typed it in, sweat on his brow. Fans roared to life like jet engines. Temperature dropped to 58°C.
Once the switch is back online, log in and run:

Confirm that the "VRP Version" matches the new firmware you installed.
S5700.cc may support S5700-LI, S5700-SI, and S5700-EI, but not S5700-HI. Always cross-reference the Release Notes (available on the support portal).display license.Instead of sending you to a generic Huawei support page that asks for a contract login, use this official, accessible starting point:
Huawei Enterprise Support – Software Download (Public access for many models):
👉 https://support.huawei.com/enterprise/en/software
(Search your exact model, e.g., “S5720-28P-LI-AC”, then filter by “VRP8” or “VRP5”)
Alternative for older switches (no support contract):
Huawei’s official technical documentation portal:
👉 https://info.support.huawei.com/info-finder/enterprise – Enter your switch model → Click “Software” or “Release Notes”.
⚡ Pro tip: Always download the Release Notes first. They contain the mandatory upgrade path and pre-checks.
For CloudEngine (CE) series switches, Huawei also distributes firmware through CloudEngine Fabric Insighter (CE-FI) or iMaster NCE-Fabric. In these SDN controllers, the firmware upgrade link is embedded inside the upgrade workflow. You can also download firmware directly from the Huawei eSupport portal under "CloudEngine Data Center Switches."
If your support portal access is limited, open a Technical Assistance Center (TAC) case. Provide the switch model, serial number, and current firmware. The TAC engineer will either:
