It's worth noting that despite higher voltages here there aren't more
deaths or injuries - but maybe it's because people take it more
seriously. Admittedly no one I know is nuts enough to use body parts
for liveness testing.

Is anyone aware of a voip-focused group similar to nanog? Us voip pukes

I was referring to, when a 120v device is attached to the 5-15 end of
the cord. On the inside of these grounded devices I often find that the
neutral is tied to ground. So in the case of the c14 being connected to
a 240v PDU when I 120v device is connected it will ground one of the
load lines.

Not entirely on subject but I thought that allowing DNS queries to
occur via TCP is mission critical for simple mail routing. We ran across
this back in the day at @Home Network. Firewall rules were changed to not
allow port 53 TCP. This severely affected sending mail to large
distribution
If the pdu contains a surge suppressor and was designed for 120v, plugging in
to 220 will cause the MOV that protects against transient over-voltage to emit
smoke. The breaker or fuse is a current limiting device.

I have some similar input. At my company, we use both 120 and 208
volt depending on what servers we are putting in the racks. We can
fill up every single rack to full capacity 100% of the time by using
energy efficient servers. The fact that it is 120 volt or 208 volt
hardly matters on most

When you say that your provider sees errors on the circuit, where are

Also, how is the DS3 being delivered? Be sure to check
