Here's what APC has to say about it:

Sorry about the wrap...

Basically, they say not to plug surge strips into the output of a UPS.
You should use PDU's instead.
Or, more basically: Buy APC's power strips, because we think we engineered them correctly, and think nobody else possibly could design a decent power strip.

Here's a URL showing some of their rack mounted PDU products

While I like APC products, I have to wonder whether this "requirement" for using only "PDU" products was written by their lawyers to cover liability concerns when someone uses a low-quality power strip, and/or their marketing folks to push their own power strips.
