juniper.net 
 => Support 
 => select any RPS-able switch, EX3300 f.e. 
 => Additional Links / EX RPS
 => Documentation
 
thats not virtually non-existent, i believe.  I recommend choosing the
pdf at the side
 =>
http://www.juniper.net/techpubs/en_US/release-independent/junos/information-products/topic-collections/hardware/ex-series/RPS/book-hw-rps.pdf

158 pages of Documentation, ranging from electrical considerations to
restrictions/limitations up to how to configure the RPS from a Switch or
VC (page 81).

if it doesnt work at all, the most probable cause is that you didnt fill
the middle of the three input slots with a PSU. (page 10 in the pdf)
both LEDs in the PSU(s) should be green, if one is red, something is wrong.

also note that according to documentation (i didnt test though), EXs
arent able to boot from the RPS. (page 5 of the pdf)
