N+1 Redundancy Explained

Redundancy Concept

You can think of N+1 redundancy as a simple way to protect your network from unexpected failures.

A simplified way to look at N+1 is if you were ordering bagels for an office breakfast. There are 20 people working in your office and you decide to order one more bagel than needed just in case. 'N' would represent the exact number of bagels you need (20), while the extra bagel is the '+1'. You would be showing up to work with N+1 or 21 bagels.

This concept applies directly to your Telecom Power System. If your network needs five rectifier modules to operate, you install six. The extra module stands ready to take over if one fails. You always have enough power to keep your equipment running.

N+1 redundancy differs from other models. Here is a quick comparison:

• N+1 redundancy handles one failure.

• 2N redundancy protects against multiple failures with a mirrored system.

• N+2 redundancy offers two backups for even greater reliability.

You choose N+1 redundancy for a balance of protection and efficiency.

Application in Power Systems

You apply N+1 redundancy to your Telecom Power System by adding extra rectifier or battery modules.
N+1 redundancy in rectifier systems means that for every N modules required to meet the load, there is one additional module included. This design ensures that if one module fails, the remaining modules can still provide the necessary power, thus preventing any interruption in service. For instance, if a system needs 15A, it can utilize four 5A modules. If one module fails, the other three can still deliver the required current, ensuring continuous operation.

You see this approach in battery backup systems as well. If your site needs three battery strings, you install four. The extra string keeps your network online if one fails. You maintain service even during maintenance or unexpected outages.

Tip: You can use N+1 redundancy in your Telecom Power System to support critical loads and avoid downtime during repairs.

Reliability Benefits

You gain several reliability benefits when you use N+1 redundancy in your Telecom Power System:
