Im speccing up a new 16A PDU for a 42u rack build, i need a PDU with IP control so that i can power cycle devices remotely. But I've noticed that most PDUs with IP control don't have surge protection on them.
I can find lots of surge protected PDUs but they tend to be "rack mounted surge protected extension leads" rather than IP controllable PDUs.
Any idea why this is ?
My thought was that i could get a IEC PDU, IP, but non surge and then plug some IEC surge protected "rack mounted extension lead type PDU" something like THIS. But if i did that although the equipment in the rack would be surge protected, the IP controllable PDU wouldn't be.
There are a whole lot of "it depends" on this one. In most cases involving a managed PDU, suppression is handled upstream somewhere.
If you are in a colo I would recommend talking to their power guys there to get their recommendation. You may have plenty surge suppression already.
If you will just be plugging these into your own UPSes I would follow the manaufacturer's recommendations. Some specifically warn against adding suppression on the load (output) side. Some have suppression built in. Contact your UPS vendor.
