Answer:
FACTORS TO CONSIDER WHEN BUYING UPS
Explanation:
Power
You must consider the power needed. The rule of thumb is to get a UPS with a power capacity that is 25% higher than your total power needed. Furthermore, you must consider its capacity for expansion.
Backup Runtime
We also need to identify how much backup runtime we will need for your UPS. Generally a UPS is needed to have enough time to properly save files and shut down the equipment before a power outage. Since this will be connected to a server, we must look at the capacity to increase the run time.
Type
There are three types of UPS.
- The standby or offline UPS
- The line-interactive UPS
- The online UPS
For a server, the Online UPS will be best as it provides clean power regardless of its input power.
Tower or Rack Mount
UPS’s are generally available as either a tower or a rack mount.
The type of mount to be considered should take into consideration where it will be placed, the airflow and the ease of fitting bigger batteries if need be.
Maintenance
The maintenance cycle of the batteries should be considered. The longer the maintenance cycle while retaining its reliability, the better.
Total Cost of Ownership
When selecting a UPS, it’s important to remember that product with lower initial cost may not always be the best long-term solution. The long term durability of such product should be placed as a priority.
Remote Access
Most UPS systems can be managed through their communication ports and a connected computer. This option should be looked at to ease maintenance during off work periods.
Warranty and After Sales Service
Warranties should be considered as it makes maintenance and replacement if batteries easier.
