Strictly speaking, don't hang a surge protector that uses MOVs for protection off a UPS that doesn't put out a real sine wave (most are kinda squarish, line power is a sine wave).
just spent 6 hours trouble shooting an application issue on two systems due to this very reason.
Paraphrased from said inspector: The inspector wasn't kind enough to elucidate what, exactly, constitutes the 'fire-hazard'.
We get dinged on the power-strip in power-strip commandment every other year or so. Typically the UPSs are placed at the very bottom of the rack due to weight, then you need some way to give outlets to servers unless you want to run a whole bunch of really long power cords :/The "fire hazard" is that the wiring inside the power strip is only rated for a given wattage and plugging more power-strips into it makes it MUCH easier to exceed the wattage and cause overheating inside the unit, with a possible fire as a result.
Sometimes I hear that it's the power strip that you shouldn't plug into the UPS.
What I haven't gotten is a clear idea of how reliable these recommendations are or how generally/specifically they apply.
Avoid circuit overload during power recovery and extend uptime of critical equipment by prioritizing the load shedding.
Metered Rack PDUs provide power utilization data to allow Data Center Managers to make informed decisions on load balancing and right sizing IT environments to lower total cost of ownership.

Plugging a power strip in "downstream" of the UPS may not be up to fire code (per @sysadmin1138 excellent response) but it's probably not going to hurt anything. There should be only one 'smart' device in-line between the load and source, which would be the UPS.
The UPS should be running as close to hard-wired as possible.Remote outlet level controls allow power on/off functionality for power recycling to remotely reboot equipment and restrict unauthorized use of individual outlets.
