The fan module has two fans to cool the chassis, and a failure of a fan does not immediately affect system operations. When any fan in a fan module fails, fix the fan module as soon as possible.
The fan module reports an alarm when a fan in it fails. When receiving such an alarm, fix the fault immediately to ensure effective cooling for the chassis.
Automatic fan speed adjustment
The switch provides intelligent fan speed adjustment based on temperature in each zone, and correlate speeds of fans in the entire chassis. The system monitors the temperature of key components, and adjusts the fan speed based on temperature changes. This intelligent fan speed adjustment function ensures that the system stays within the proper operating temperature range, and reduces power consumption and noise.
Hot swapping
Supported
Other fan modules are not affected when you install or remove a fan module.

EH1M00FBX000 FAQ
Q1: Is this firewall module compatible with the Huawei S12916 flagship switch? Is an additional firmware upgrade required?
A1: Fully compatible! It supports the entire S12900 series flagship switches. Firmware versions V200R023C00 and above can be used directly without additional upgrades. It automatically recognizes and enables flagship-level security features after insertion.
Q2: Is the 20Gbps throughput unidirectional or bidirectional? Can it meet the high bidirectional traffic demands of ultra-large data centers in actual deployments?
A2: 20Gbps is the bidirectional throughput (total bidirectional). In actual deployments, it can easily handle 20Gbps concurrent bidirectional traffic in ultra-large data centers. The dedicated security chip has no performance degradation, and the forwarding latency is <1ms.
Q3: What are the core differences between this and the Huawei EH1M00FBX001 (standard grade)? How to choose?
A3: The core differences lie in performance and compatible devices: EH1M00FBX000 (20Gbps, tens of millions of concurrent connections) is compatible with the S12700/S12900 flagship device, suitable for ultra-large core networks; EH1M00FBX001 (10Gbps, millions of concurrent connections) is compatible with the S9300/S9700, suitable for medium to large networks. Choose the flagship device for ultra-large core scenarios, and the standard device for medium to large scenarios.
