I'm interested to know if anyone has ever installed SOHO equipment in IP67 (waterproof) enclosures.

I'm looking to install a Draytek VDSL router and a Mikrotik RB750GL router in the ground and concerned about heat build up. If I use a metal access hatch (think man hole cover), this could be used as a heatsink, but ultimately the gear will be in an air and watertight box.

Thoughts?

It has to be in or under ground as it's not on my property so need to comply with the conditions of my easement.

This sounds like a bad idea :P do you not have room for them inside your house?

Yes, but needs must.

I'm Rural and it's to reduce 96 metres off my VDSL run. I'm on the cusp for VDSL, so this 96 metres means a huge difference in speed. I already have my modem connected where the line enters the house, but based on tests Chorus did at the roadside, it will double my download speed and increase the upload six fold.

Ah! So that makes sense.

No way you can hang it off a fencepost or similar? I suspect that will be a lot easier than burying something. You can then bring the cables in through the bottom (via grommets) and provide some vents if needed, without letting rain in.

cant say i have much to comment on the heating, but interested in this none the less.

for me, ive been looking to do this, with about 230M of drive to the road however.

Would you not be better off sticking just the modem at the entry point, then you have less load on PoE (assuming your not planning to run power to the point).

Added advantage of there only being one device you have to go outside if you need to physically do a hard reboot on too.

I run a RaspberryPi in a weather-proof box on the side of my house for ADS-B flight tracking. I've got another on the side of the building at our Sydney office, and it survives the heat and direct sunlight without problem.

I agree with hio77 - put only the bare minimum of equipment in the pit. I'd put the modem and power supply. try for 802.3af/at PoE if you can - one less cable to run. I use a TP-Link TL-POE10R inside my box to power the Pi from my PoE switch in my office. You should be able to power a VDSL modem the same way.

That's a good point, no real need to site the router next to the modem, fast ethernet can go 100m on cat5e, I have read that up to 500m is possible on cat6 but PoE might be getting sketchy at that sort of distance. I wouldn't think 200m was too much of a stretch if you're just powering a modem.

I actually have two VDSL connections, so plan to put two VDSL modems in the box and VLAN them back to the house.

In your case you probably don't need to go underground. As for your 230m run, you'll probably hit the length limit for ethernet. In theory it's 100m, in practice, 150 metres is easily attainable with modern cabling. Take a look at a mikrotik Map 2N - It's supposed to be a wireless access point. It's smaller than a pack of cigarettes, can be run on up to 57 Volts DC, runs on minimal power, runs Mikrotik router OS, PoE IN on one port and PoE OUT on the other. It makes for a great ($70) PoE and Ethernet repeater for those really long runs.

Ah, for the Vlan, yeah that makes sense, so your actually sticking two modems in there?

Defiantly have to look at the RBmAP2n, certainly a cheaper solution than going with a POE Extender

You can't do 230m over Ethernet. This is the major stumbling block with your plan. You'll need something half way to avoid issues.

the OP's is only 97m, hio77's is 230m :)

Since it is VDSL surely 100mbit per modem will be fine. If so 100baseT only uses 2 pairs out of the 4 in a cat cable. So just stick those ethernet double adaptors on each end.

Forget putting active gear in a pit. No matter how hard you try (and what the IP rating is) water will always get in.
Needs to be in a proper IP67 enclosure that is PROPERLY installed above ground.

Then you would run a cat5e (underground rated) and a two-core electrical cable (a 2.5mm 2-core TPS would work well). Don't think they need to be isolated from each other as the voltages are so low.

Then you pump some DC voltage to your box from the house to power your gear. If you had 48V at the house there will only be a few volts lost by the time it gets to the gate. But you will obviously need a voltage regulator to keep things consistent for your devices.

Now for the data.....
You simply install a VDSL bridge on one of the pairs of the cat5e. This should easily do 100Mbps over that distance. Also they are layer 2 so you can VLAN to your hearts content.

Edit: Just read the link is only 97m. Don't worry about vdsl bridge. Just run two cat5e and do away with mikrotik. Cable is cheap =)

What do you mean by VDSL bridge? Do you mean a modem? Or an active VDSL repeater?

I don't have an option to install above ground. I'm still looking into options at the moment.
