These days a lot of businesses rely on electronic equipment for their industrial processes, communication facilities and data processing. These are sensitive equipment that should be protected from sudden outages and from disturbances that can affect main power supplies and their attached equipment during regular operation which includes surges, spikes, brownouts and frequency and voltage variations.
A correctly-specified uninterruptible power supply (UPS) battery backup can guarantee protection. The question that arises here is how managers and engineers can monitor UPS, to see if they are fit and how can they protect their client’s load? Moreover, how can you effectively apply this function to UPS and distribute it around operational or across various enterprise sites, which in some case could be unmanned or located in remote areas?
To ensure the its success, UPS must effectively communicate with critical load and with central manager. For instance, if the mains fails, the UPS should be able to warn its significant weight, which would allow orderly shutdown before the autonomy of it is compromised. Otherwise, the autonomy might only delay a catastrophic crash instead of preventing it. At the same time, the information that is transmitted to a central manager regarding the health of the UPS and its components will give an insight into the problem areas in advance to prevent any fatal disaster or system failure.
Let us talk about the next thing — SNMP and UPS.
Modern uninterruptible power supply must be well equipped with SNMP capability. Usually, it consists of a network adaptor that can connect the UPS system directly to the computer network, so that the UPS turns into an intelligent network peripheral device.
To begin with, SNMP is a vendor and a platform that is independent and establishes guidelines regarding the information that needs to be collected, how it will be structured and how messages will be formulated between the network peripheral and manager.
The next step is where the network peripherals gather all the data into a Management Information Database (MIB). Operating system software employs SNMP management tools, which will collect and display the MIB in a more consumer-friendly format.
Physically, the SNMP adaptors are either separate enclosures or slot-in cards and are usually placed between the UPS serial communications port and the network. Now when you are talking about the different levels of monitoring and shutdown facilities, it varies between manufacturers, and it is crucial to understand precisely which functions are required before you specify what adaptor.
Moreover, whatever software you are planning to adopt must also be picked carefully for compatibility with the network operating system. Furthermore, major UPS manufacturers support Windows, Apple, Linux and UNIX. In addition to that, there are various options to pick from, but it can be majorly divided into a smart UPS and industrial UPS.
In closing, we would like to conclude that UPS must communicate their status to avoid any kind of catastrophic power failures and any long-term issues. To help communicate this problem across a large site, or various sites, it can be solved with the help of the SNMP protocol, as its different devices and operating systems can share information for display, analysis and action.
