Most Servers and high end Network devices have 2 Power inputs ,But Many other devices like basic switches as an example have only one, So even if the Server is Up and running in case of shortage , if there is a problem with the switch... , the switch will go down because it is on a differrent circuit ... So nothing would work .
How can i Set up power redundancy for those with one power input ? Better of using Separate UPS ? Or Buying the same network equipment ?
Whats are the pros & cons ?...And anything else i should know regarding it ? Any other way of doing it ?
