Does ONT reboot after a power failure?

Message 1 of 11

I live in an apartment which has a utility room(AKA computer room). My computer & FIOS TV are in the computer room.

 

I want to reorganize the computer room & clear up the rat's nest of cables.

 

I have a surge protector & a UPS. Right now, the ONT is plugged into the battery backup of the UPS.

 

If I'm watching TV in the computer room & there's a power failure, there's no big deal. But if I'm on my computer, I want the UPS to supply power long enough for me to properly shut down my computer.

 

I assume that the ONT will reboot if there's a power failure, right? I know that the router will reboot after a power failure.

 

Should the router & ONT be plugged into the battery backup of the UPS or does it really make no difference whether the ONT & the router are plugged into the UPS or the surge protector?

The ONT does not have a power switch.  It turns on when power is applied to it, plain and simple.

 

The reason to put the ONT and router on a UPS is to provide internet service during power outages.  If you don't care about having internet service during outages, plug them directly into the wall.

Note that power strip surge protectors are mostly useless.  A surge protector is only as good as it's path to ground.  Most power outlets have a long, convoluted path to ground through the wiring back to the main panel.  Every wire nut in the ground path significantly reduces the ability of the surge protector to dump current.  If you really want to protect your equipment, install a whole home surge protector on the main panel.

 

If your outlet happens to be directly connected to the main panel through a short run of low gauge ground wire, disregard the above statement.

I have 2 surge protectors. A Philips in the living room & an APC in the computer room.

 

I guess that they are better at protecting equipment from surges than power strips. I guess.

 

I think that read somewhere that surge protectors have metal-oxide varistors. According to Wikipedia, "When used as protection devices, they shunt the current created by the excessive voltage away from sensitive components when triggered."

 

I guess that power strips really don't provide protection. They just allow multiple devices to be plugged into 1 power strip.

 

I found this online: It is important to note that not all power strips are surge protectors. While they look very similar, the sole purpose of a power strip is to add extra outlet space. Sometimes it is difficult to tell the difference if it does not come right out and say so. You can look at the packaging when you are figuring out what exactly you are purchasing. A surge protector should have a joules rating on it’s packaging.

 

I live in an apartment. I doubt if management would allow me to install whole home surge protector.

All surge protectors work the same way - they shunt excess voltage to ground.  It doesn't matter if we're talking about a panel mounted protector, a protector in a power strip or a stand alone plug in protector.

 

The problem is any protector is only as good it's ground.  If the ground is a long run with lots of splices and wire nuts, it will not handle high current surges well.  The result will be a lifted voltage on the ground at the protector, due to the resistance in the ground.  When surges occur, the protector can shunts tens of thousands of instantaneous amps or more through the ground.  It doesn't take much resistance to raise the voltage with that much current. That raised voltage can cause problems.

 

Panel mounted protectors work the best, as they have a very short connection to ground.  They also protect all devices on panel, which can be a significant cost savings.

 

In short, a plug in surge protector is only slightly better than nothing.  It will help with smaller surges, but it won't do much against a decent sized one.  If you can't install a panel protector, these are the next best thing.  But don't spend a lot of money on them.

 

Many protectors offer "connected device warranties."  Be sure to read reviews of how the vendor handles claims before you put much value on them.  Not all warranties and vendors are the same.

I don't completely understand what you are talking about.

 

I read online something about joules. The higher the joule rating the more voltage can be shunted to ground. And the more expensive the surge protector!

 

I definitely want to plug my computer & monitor into the battery backup of the UPS. If there's a power failure while I'm on my computer, the UPS will supply power long enough for me to properly shut down my computer.

 

So, from what you say, it's my decision whether to plug the ONT & router into the battery backup part of the UPS or into a surge protector.

The ONT and router can be plugged into a UPS. This is preferred over purchasing the power bank sold by Verizon which only keeps landline service going during a power failure.

 

Many commonly purchased UPSs connect the load directly to commercial power, but can adjust the power delivered to the load as needed. When power fails, there is a fast switch over to the power stored in the batteries. I refer to these as "standby models".

 

Other UPSs are "double conversion" models in that they take commercial AC power, rectify it to charge the internal batteries and invert it back to AC power to run the load. The loads are constantly being fed by power derived from batteries.

 

The double conversion models tend to cost more than standbys. Which type of unit is selected is a matter of personal preference.

I'm saying that plugin surge protectors are a waste of money.  As you noted, they all shunt to ground.  Grounds on most plugs are not good enough to handle the shunted current without causing problems.  A surge protector is only as good as it's ground, no matter how much you pay for it.  If you feel you must have a surge protector, don't spend a lot of money on it unless you know you have a ground designed for shunting surge currents (you most likely don't.)

 

As I said in my first post, it's up to you if you want to plug your ONT, router and other networking gear into a UPS.  I do this, as I want my network to stay up during outages.  It's your equipment; plug it into whatever works for you.

I read online that some surge protectors cut off the power to the plugged-in devices after the MOV fails.

 

How does that work? The surge protector is still plugged into an outlet.

 

HMMM, now that I think about it, I really don't need a UPS. I've had UPSs for years. Back when desktop computers had physical hard drives, a UPS was a good idea. It supplied power long enough for me to shut down my computer without a head crash. Nowdays, computers have SSDs which don't have heads.

 

I know that you stated that surge protectors are worthless, but I don't want to plug my expensive computer equipment into a power strip. A little protection is better than none at all.

A UPS is a good idea if you want to keep equipment running for some period of time during outages.  If you use devices with batteries, such as laptops, phones and tablets; a UPS isn't as critical for them.  If you have devices that don't have batteries, such a desktop computers, set-top-boxes, media servers, and NAS boxes; a UPS can be very useful.  Even though an SSD won't crash like the heads on spinning rust storage, a power outage can cause SSD data loss if pending writes haven't completed (writes can be cached on modern devices.)

It really boils down to what kind of devices you have, how important your data is, how good your backups are, and how much budget you're willing to allocate to power outage protection.  Different people have different perspectives on these issues, so find what works for you.

HMMM, I've had 1,300 VA or 1,500 VA UPSs. If all I want to plug into a UPS is the computer, monitor & printer, I don't need a 1,300 VA or 1,500 VA UPS. I can get a smaller one.

 

And the batteries are expensive! A replacement APC brand battery for my APC UPS costs $80! I didn't pay much more than that for the UPS!

 

I've noticed that the joule rating on UPSs is less than the joule rating on a surge protector. For example, APC makes a surge protector with a joule rating of 4,320. My 1,300 APC UPS has a joule rating of 384.
