Does the redundant power supply have a battery
I call you lucky! Tying batteries directly together provides more capacity, not redundancy. Look at my simple failed case above, or just think for a moment at why not put in a redundant power system in? Honestly, it does cost much, and if one power source happens to fail (battery, cable, regulator, BEC, etc) you are covered!

Why do engineers usually short ground and negative ports on a DC power ...
Short answer: it can prevent damage to the power supply equipment.; Long answer: When its not shorted it means that the power supply is "floating" (i.e. NONE of the terminals is connected to ground) --> thus, although a specified voltage is maintained b/w the +ve and –ve terminals BUT the voltage b/w either +ve and ground OR –ve and ground terminals is …

hardware
As others have stated you have multiple power supply units for redundancy. Normally in a data center you would connect one half of the power supply units to feed A and the other half to feed B. Than when the DC does maintenance on their feeds your equipment wont go down, crashing applications, corrupting a DB or something else.

If my power supply is 700w, do I need a 700w UPS?
For example, a server may have two 600W power supplies in parallel-redundant mode, for a total power rating of 1200W. But the steady state power consumption in this case will be less than 600W. In another example, a high-end workstation with an 850W PFC power supply may only consume 350W under normal operation.

UPS Design & Redundancy Decrease Downtime
"2N" Configuration. The next step in UPS redundancy utilizes two independent "N" systems to support an "A" side and a "B" side power source for the critical load. In this case, a failure of the "A" side system would typically not affect the "B" system. This would be considered a "2N" UPS system. The critical load should either be a dual-corded power supply system or ...
How to calculate my UPS requirements
QUICK TIP: The PowerEdge supplies are redundant and will share the power equally. So if you have an existing UPS with the second power supply plugged directly to utility, then your total power draw on the UPS during a power outage will be twice what you see on the single UPS when the power is on. That might help you bypass all the estimation ...

UNDERSTANDING HOT SWAP N+1 REDUNDANCY
A redundant power supply is often called an N+1 power supply, and consists of two or more power supply modules contained in a single chassis. The power supply is usually specified so that if one module goes down, the remaining modules have the capacity to supply the load. The failure of a module should not cause any disturbance to the DC
The best UPS to power a modem and router : r/batteries
You lose a lot of power in this conversion alone. Probably more power is lost to this conversion than power consumed by your router. You are better off with a 12V battery connected to battery charger all the time and a buckboost converter circuit to maintain 12V supply that you can provide directly to your router.
