Product Review

The Fortinet FG-400E offers a comprehensive set of features with its 16 GE RJ45 and 16 GE SFP slots, along with 2 GE RJ45 management ports and included transceivers, catering to diverse networking needs. However, the device's power consumption, peaking at 214W with a noise level of 48 dBA, might be a concern for energy-conscious environments or those requiring low noise levels. Its rack-mount form factor, 1 RU height, and operational temperature range from 32°F to 104°F ensure compatibility with standard data center environments, though the weight of 16.4 lbs could be a consideration for physical handling and installation.


The Fortinet FG-400E is a comprehensive networking solution designed to meet the rigorous demands of modern network environments. This device is engineered to provide unparalleled performance and reliability for businesses of all sizes. With its compact design, the FG-400E is ideally suited for rack mount installation in data centers and IT closets, occupying only 1 RU of space. The dimensions of this unit are 1.75 inches in height, 17.0 inches in width, and 15.0 inches in length, making it efficient in terms of space utilization. Weighing in at 16.4 lbs (7.4 kg), it strikes a balance between durability and portability. In terms of power requirements, the FG-400E operates within a broad range of AC power inputs from 100–240V AC, at 50/60Hz, with an average consumption of 109 W and a maximum draw of 214 W. For environments utilizing DC power, it supports input voltages from -48V to -60V DC. This device is also 80Plus compliant, ensuring efficient power usage. Despite its power, the FG-400E maintains a heat dissipation rate of 730 BTU/h, keeping thermal output manageable. The noise level is rated at 48 dBA, which is comparable to the ambient noise in a quiet office, ensuring that it does not intrude on workplace concentration. The operating conditions for the FG-400E are designed to be flexible, supporting a minimum operating temperature of 32°F (0°C) and a maximum of 104°F (40°C), with a humidity range of 10%–90% non-condensing. This allows the device to function reliably in a wide range of environmental conditions. Storage conditions are similarly broad, with the device capable of withstanding temperatures from -31°F (-35°C) to 158°F (70°C). Connectivity is a strong suit of the FG-400E, offering a total of 32 hardware-accelerated ports split evenly between GE RJ45 interfaces and GE SFP slots. This provides flexibility in connecting a wide range of devices and fiber connections for high-speed networking. Additionally, it includes two GE RJ45 management ports for efficient network management and comes with two SFP (SX 1 GE) transceivers.
