Grounding IP OFFICE 406

[mk81596]

We have an IP office 406 and it was installed and not grounded. It is in our data racks so is that a good enough ground. I am new so just trying to figure it out. The cabinets from what I can tell are not grounded.

Thanks

on the back of the 406 is a screw (in the middle)
there you can put your ground on

I do know where to ground it. I was just wondering if it is needed if inside the rack.

 

[tlpeter]

yes you need too

i ground the ipos that i install to to a itxlink towermax ksu surge protector. it as a screw terminal on the top of it and then grounds to the outlet via the grounded plug. assuming the outlet is installed right.

I always ground my systems to a good ground either building steel or cold water pipe. I did one on a site with a raised floor and the floor was grounded and i did some testing with a multimeter and found that the system would pick up its ground from the rack. The rack was toggle bolted to the floor and then the IPO just being screwed to the rack would pick it up on the ground screw. I still always run a separate ground but just thought i would throw this out there.

If it helps - We went through 3 units until we found the problem was the installers did not ground the unit. Ever since then we haven't had a problem (knock on wood). I would definatly make sure the units are properly grounded per the specs. Don't count on the rack grounding to be sufficient.

Our IP Office system is grounded via the grounding screws to the server racks and in turn the server racks are grounded to building steel with #4 copper. I would rather overkill the ground, than have a potential for a ground loop. So IMO, they most definitely need the additional grounding via the screws to the racks. It's certainly easy enough to implement.

They key is check and never ever assume.

Recently the local power company did some work on our sites transfomer and so wheeled in a big generator rig on a flat bed to provide our power for a few days. I so wanted to gather all the software engineers in front of it and point to the ground - one very solid iron spike driven into the earth and a serious cable from it to the generator - as we say 'proper job'.

I used to work on equipment for newspaper printing presses which can generate scary amounts of static potential (a printing press is just a Van de Graaff generator after all). What with very volatile inks in the building also the safety guys were grounding crazy with good reason.
