[AusNOG] Question about hardware spec for a DC

[Tony de Francesco]

Something I did learn from looking at aftermarket auto transfer switches is
that not all of them can handle two power feeds that are not synchronised
(whether that is a potential issue for your site of not?).



Worth asking the question.





Kind Regards



Tony de Francesco

APC make a 1RU ATS. Seen a few of them around the place.



http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=AP7721

SKU: AP7721 - $750ex Wholesale

2 x IEC C14 240v Input and 12 x IEC C13 Output

10A Max Power Draw



There are other cheaper alternatives but what price do you put on your gear
and power.



At least with the APC gear you know what you're going to get.



Cheers,

+1 to James's comment.



We have hardware in our racks that only has 1 power unit (like switches and
routers) so our work around for this is a 1RU APC PDU that connects to both
of the power feeds in our rack and the device connects to APC PDU.  So in
the instance that feed A is disrupted, we still have feed B and the APC PDU
picks up the transfer instantly from our testing.

Dear Alex



As an internal policy we make sure everything we invest in has a minimum of
two power supplies, but this is an internal policy not a standard per say.



Kindest Regards

A question for the list.



When you buy equipment for a DC, would you expect it to come with dual
power supplies, either as an option or as a standard?
