What’s more, there is no big price difference between a normal switch with a single power supply and a switch with redundant power supplies. However, a redundant power supply solves unnecessary downtime and data loss caused by accidental power damage. This is why they are only used in situations where uptime is extremely important. The one downside to a redundant power supply setup is that it takes up more room within the device itself. Is It Necessary to Get a Network Switch With Redundant Power Supply?Īlthough the redundant power supply could offer many conveniences in different aspects, it has one shortcoming as well. Equipment that operates using multiple power supplies will allow you to simply unplug the defective power supply and plug a new one physically. If one of the power supplies stops working, you will typically be able to replace it without taking the device offline. Normally, network switches with two or more power supplies support hot-swapping. Note: In partially redundant power solutions (1:N), it takes time to come online in the event of a power failure leading to an outage. Under such circumstances, the power supply offering compensation could be regarded as a backup of the power in the whole network. Guarantee the Continuous and Normal Operation of the EquipmentĪssuming there are two power supplies, if one power supply is powered off for some reason, the other one will immediately compensate to provide full power to the device so there is no downtime at all. It has dual power supplies with the same advantages listed below: Normally, there are three main advantages of using a switch designed with a redundant power supply. How Can We Benefit From a Redundant Power Supply? However, in a switch of full redundancy, one power supply may also be idle due to different manufacturers. The two power supplies will be powered on and work at the same time. Normally, the dual power supply in a network switch usually refers to full redundancy. Here is the scheme of the two different types of power redundancy: When there is a power failure in your network switch, the power supply needs time switching from one source to another. In partial redundancy, there is one extra power supply for multiple switches. This scheme is also called 1:1 redundancy (or 1+1 redundancy sometimes). In full redundancy, every switch is attached to two power supplies, so that if one goes down, the other takes over. The power supply redundancy could be divided into two types, namely full redundancy and partial redundancy. Now, it is prevailing in many networking devices like network switches as well. It is usually used in servers and other highly important computers, to minimize the chance of a complete computer shutdown or failure. This makes sure that the device could operate normally even if one power supply fails. Each of the power supplies will have the capacity to run the device on its own. Then, what is a redundant power supply? How can we benefit from it?Ī redundant power supply is when a single piece of networking equipment operates using two or more physical power supplies. This may be a challenge when dealing with network applications that require redundant power to ensure reliability and continuous availability.
