If manual restart is chosen, there will be delays depending on the level of service provided by personnel regarding the device. There are generally three levels of service level:
1. manned: 1-hour response time
2. Telephone alarm: 4-hour response time
3. Unmanned: 24-hour response
Considering these factors, the equipment downtime caused by communication power supply issues has become very serious.
After increasing the use of UPS, there will be three other situations that affect system downtime. They are:
1. If the power outage time is shorter than the UPS operation time, UPS can provide normal power supply, eliminating the impact of power outage on the system.
2. If the power outage time is longer than the UPS operation time, it delays the impact of power outage on the system.
3. UPS itself may experience malfunctions, leading to power outages
It is evident that the advantage of APC UPS lies in reducing power outages. When the UPS installed does not consider equipment operation or service level, the frequency of power outages is reduced.
Considering all factors, it can be seen that adding APC UPS will significantly reduce downtime, but the extent of the reduction will be largely influenced by the level of service provided to the equipment and the operation of the equipment.
1. A UPS may only slightly reduce downtime, or it may reduce downtime by three orders of magnitude, depending on the selected UPS type, equipment operation, and service level.
2.If we switch from using a UPS that can run for 5 minutes to a UPS that can run for 1 hour, the downtime rate can generally be reduced by an order of magnitude.
3.To achieve the policy of 99.999% normal operating time, it is required to arrange UPS or UPS equipped with generators that can operate for more than 1 hour.
4. In an unmanned address, it is necessary to install a fault-tolerant (N+1) UPS and a generator to achieve the policy of 99.999% normal operation time.
5.After installing UPS, the system that requires manual restart benefits the most in extending normal operation time.
Power outage is a primary obstacle to achieving the 99.999% normal operating time policy (with only 4.8 minutes of downtime per year). For long-distance addresses that require manual restart of the system, the downtime will reach 4000 times that of 4.8 minutes, while for the I system deployed by general companies, the downtime may be 23 times that of 4.8 minutes. UPS can significantly extend its normal operating time. But if we want to achieve a reliability policy of 99.999%, we may need to deploy UPS systems that operate for longer periods of time or UPS systems with generators.
This article does not address the impact of other power issues other than power outages; High voltage and transient voltage issues can also lead to an increase in downtime, affecting system performance, and therefore require prevention measures. The use of APC UPS can also help eliminate such problems, so the benefits that APC UPS brings to users far exceed the advantages introduced in this article.
