The "CTS-PWR-AIR-INJ5+" can be ordered when we purchase CTS-CTRL-DVX-10 from Cisco
and the "CTS-POE-INJ" can be ordered when we purchase the CTS-SX20-PHD12X-K9 from Cisco
both of them are used by the Touch 10 (CTS-CTRL-DVX-10) for the SX20
what is the difference between them? are they actually the same thing?
