RE: Orange Power Outlets

I'm not sure, but I believe the orange outlets mean that the outlet is protected with backup power, e.g., a generator, in case of lost power from the grid. I've seen these in hospitals. I don't know if it's in the NEC or not. Anyone? Regards, John Kretsch -Original Message- From:

Bellcore Redundancy Requirements?

Does anyone in the collective know about _where_ Bellcore spells out any sort of redundancy requirements. There is a buzz about L-10 requirements and I'm not sure where this comes from. TIA. Regards, John Kretsch --- This message is from the IEEE EMC

Hygroscopic Dust Troubleshooting

I thought I would try to contact the collective on this one... We have a shelf system that is failing GR-63 hygro dust with excessive bit errors (unit did pass Gaseous contaminants no problem). Air is filtered. Anyone have experiences that they would like to share (non-proprietary of course)

Cell Phone SAR Requirements

Hey Folks: Here's an article about cell phone manufacturers providing SAR info right on the boxes. But, what's interesting, they don't have to put the data on the box, just how to get it from the FCC. http://news.excite.com/news/ap/000717/18/cell-phone-radiation Regards, John R. Kretsch,

RE: Network Card Certification

Just to add a little to this... Make sure UL1950 is 3d edition... And I don't believe Clause 6 applies since you don't direct to the PSTN. Thus, no FCC Part 68 either. Don't forget about EN 55 022 and EN 55 024 if you're selling in the EU. Check with the lab that you'll use for testing for more

Needle Flame on Fiber Loop

Anybody have any decent solutions to passing GR-63 needle flame with regards to fiber service loops and their associated connector boots? This has to be a common problem. Regards, John R. Kretsch, P.E., N.C.E. Manager, Design Assurance Engineering ADC Broadband Communications

RE: modest proposal

I had to throw this in here wink. This came from a friend of mine...the source I do not know. Remember, this is a joke :) Let's just make sure we don't all start speaking New-Speak a la 1984. The European Union commissioners have announced that agreement has been reached to adopt English

Laser Warning Label

Can anyone point me to a source regarding the clarity of the laser warning label per CFR 1010? I'm talking about things like size, fonts, etc. We need to attach a pretty small label to the front of a product. Regards, John R. Kretsch, P.E. Manager, Design Assurance Engineering ADC Broadband

RE: Question on FCC Class B certifications.

Just out of curiosity, how come assembled from FCC Class B compliant components seems to fly but CE + CE = CE obviously does not? What am I missing here? BTW, I don't have much faith taking a piece of equipment that has been assembled from FCC Class B compliant components to a test lab and

RE: isolation of battery (72V max) input

Moshe: We treat the 48V input as a secondary voltage with primary voltage rules. Therefore, you will have to hold to the _reinforced_ distances for creepage and clearance. Regards, John R. Kretsch, P.E. Compliance Engineering Supervisor ADC Broadband Communications john_kret...@adc.com
