Moving a network project from an office rack to an outdoor cabinet or factory floor hampers its performance. The switch that offered flawless indoor service for years might fail within weeks when placed outside.
When switches are industrial-grade, like Cisco industrial switches, it means the device has been engineered for factors like electrical surges, temperatures, and vibration. A simple enterprise switch will not withstand these conditions, as it is not designed for this purpose.
There is a difference between office and industrial gear, and people need to understand that.
A typical office switch is rated for temperatures in the range of 0°C to 40–45°C, which is more or less office temperature. They last for several years when used in that temperature range.
An industrial switch, on the other hand, is rated for -40°C to 75°C. These switches reflect real deployment conditions such as a substation in Alberta in January, a roadside traffic cabinet in July, and more. Apart from temperature changes, there can be humidity in some situations.
Cold impacts electronics much more than heat. Capacitors lose capacity, components can become brittle, and connectors can crack. Industrial switches have high-grade components in their capacitors and connectors, so they are not affected by extreme cold or clogged with dust in the heat.
The majority of office switches are designed to run on standard AC power from a wall outlet. However, most industrial sites run on DC power of 12V, 24V, or 48V. Industrial switches also support dual power inputs.
Office switches are generally fixed. Industrial switches get installed inside a moving vehicle, on a constantly vibrating machine base, or even near compressors, heavy equipment, or conveyor systems. The wear and tear is on the higher side in such cases.
Standard switches have consumer-grade components and solder joints, assuming that the switch will not move. Over time, micro-fractures develop in the solder joints, and connectors become loose due to vibrations. There might also be intermittent failures that are difficult to locate.
Industrial switches are tested against vibration and defined shock standards. These switches have more rugged physical connectors, so there is minimal chance of a cable coming loose.
A factory or substation is not as electrically quiet as an office. In industrial setups, there are welding equipment, motor start-stop transients, switching transients from heavy machinery, and lightning strikes near outdoor cabinets.
A standard switch has minimal surge protection. An industrial switch has surge suppression on data and power inputs. It also has better isolation to resist electromagnetic interference.
Summing it up
An industrial-grade switch is built for a harsh, unpredictable environment. Hence, it is widely different from a standard switch. The price difference between the two switches is also real. Confirm the requirements before you invest in a switch, whether it is a standard switch or an industrial-grade one. Make sure that you have access to all the necessary details.
