Re: [nznog] Any NOCs seeing alarms in the Tauranga Chorus exchange?

That seems very odd Jesse. Especially considering that in all major exchanges they have a separate rectifier rack and battery bank on the A side to the B side, so if a rectifier failed and took the other rectifiers down, we should have seen one of the -48VDC feeds stay up (or at least that is what I would have expected). All the same, I'm keen to know what actually happened. Sounds like some more major has happened. On Sun, Sep 13, 2015 at 4:44 PM, Jesse Archer wrote:

We're back up.

It appears a rectifier (1 of 8) failed and its failure tripped the other units.

The battery backup doesn't appear to have done its job hence voltage drop to 32V and thus your equipment powering down. On Sep 13, 2015 16:39, "Craig Whitmore" wrote:

There seems to be a power outage in the exchange affecting all chorus circuits. UFF seems to be broken as well .

We've lost power in the colo room, to both A + B feeds.
