How long will a 635 VA UPS power the FiOS ONT and Router?

Post by Arnie Goetchius
I know that the FiOS battery backup in the ONT will power the phone for
6-8 hours. However, it does not power the Internet or video except for
about 10 minutes. So I plugged the ONT and the router into a 635 VA UPS.
Can anyone tell me how long this will last?
I read somewhere that the ONT may draw about 40 watts and the router
about 10 for a total of 50 watts. Does that sound right?

I have heard 40watts for the ONT power supply but I think that is maximum
power consumption when the power supply is also charging the 12vdc 7.2ah
lead-acid battery. I think it is more like 10-15 watts quiescent power and
rises to 40 watts if charging the 12vdc battery.

The router is way off. I just looked an the power supply my ActionTec is
rated 110~120vac @ .45amps.
Assuming a nominal 110vac @ .45 that 49.5 watts or ~50watts for the Router.

So I think you are looking at something like 65 watts quiescent and 90 watts
if the ONT power supply is charging the battery.

Frankly I don't know how long it will last but a .635KVA UPS is supplying
something like 450watts.

I have an Actiontec MI424-WR and the power adapter says 3amp - 15 watts.

Hopefully, I can get a couple of hours out it so I can send emails to
friends and family telling them that Sandy shut off my power.

There is no way the AC side is using 3 amps so you must be looking at the DC
side which is wrong. You need to look at the AC power consumption which is
what the power supply and the router consumes. To convert AC to DC there
"must" be power lost

That's why I posted "110vac @ .45 that 49.5 watts or ~50watts". I am using
a MI424WR Rev.E.

Always remember you work on worst case scenarios and the total power used is
consumed power (load) plus power losses (AC/DC conversion).

OK, I will use 50 watts for the router. Thanks for the education!!

I was hoping to test out the length of time it would last when we lost
power at 9pm on 10/29. However, at 10pm we had a tree go down breaking
the pole, electric and Fios cable so not able to continue with test.
After spending a few days of misery with no heat, TV, Internet or
telephone, I moved into a motel in North Philly where every thing works.

What a downer!
Just remember to Lysol your fridge when you get back :-{ . Cheers, -- tlvp

My parents were thinking road trip but, they got there power back.

Still no power and still in motel. They say power will "likely" be back
on Wed. Of course, Verizon says they can't repair the FiOS cable until
the power is back so it will be a few more days before I can access
internet at home. Have to find something locally that has a secure wifi,
possibly the local library.

That's ridiculous. They don't need grid power to use a TDR to
find fiber breaks and fuse them with a splicer.

Of course, it's a GREAT excuse to the subscriber -
"It's not OUR fault..."

Wonder how the excuse changes when you tell them "I have power
here but no FIOS..."

They don't have to look for a break. They FiOS line from the pole to the
house is broken by a tree lying on the FiOS and power cables. They won't
be able to do anything until the tree is removed and the power cables
are lifted off the ground. The tree has to be removed by a JCPL tree
crew because the power cables are all tangled up in the tree. If the
tree is removed and the power cable is lifted off the ground and hooked
back up, even if there is no power, Verizon could then safely proceed
with the repair of the FiOS line.

I don't know if it is easier to fuse the break or run a new drop.
