Re: Want to move to all 208V for server racks
by Mark Kent 02 Dec '10

"Why do we install 120v instead of 208v?" was asked over a year ago either here or on cisco-nsp. It generated a long discussion, but it should have been cut short as early in the thread someone said all that had to be said: "because we are idiots." -mark

We called into Level3, but they "weren't aware of any issues". Not accepting that explanation for things, we eventually looked at Internet Health Report and saw a latency of 115ms and packet loss at 33% between at&t Chicago and Level 3 Detroit. So if anyone has more information, I'd appreciate it. thanks, -James

We have run into some reasonably recent flat panel LCD's not running on 208v; we began having our colo build the new cages we order with 208v a few years ago and then found we couldn't use one of our crash carts in the newer cages until we replaced the monitor. If you're doing colo, some customers may have rack mounted LCD panels that could be an issue. And this was not a power brick monitor, straight plug.

You can use one AS and communities to seperate your traffic/policies. -jim ------Original Message------ From: Ryan Finnesey To: NANOG list Subject: regional ASN's Sent: Dec 1, 2010 1:13 PM I see various people are recommending networks setup regional ASN's. I am in the process of setting up a new network which will serve as a transit network for all our operating units. I was planning on using one ASN for North America, Asia and Europe. Is this not recommended? Cheers Ryan Sent from my BlackBerry device on the Rogers Wireless Network

Anyone know where I can buy cage nuts and rack screws locally near SAVVIS DC3 in Sterling, VA? They don't seem to have a local supply here, and somehow the racks we bought came with a 2:1 screw:nuts ratio. -cjp
