I decided to edit this since it got moved to a different place where it might not be understood:
I have a UC320w phone system. I have SPA508g phones. I have a cisco POE switch next to the UC320. But, I have one far location that has one ethernet port and we want 3 computers and the SPA508g phone. I don't have a POE switch and I'd prefer to put the switch before the phone. (the out port on the phone is 10/100 where I'd like the link to the far switch to be gigabit).
The SPA508g didn't come with power cords. I know I can get them.
But I happen to have an Aironet 1200 access point power enjector: AIR-PSINJSYS1200. I think the aironet needs 48 volts, so I assume this power injector provides that (or up to that?).
Is that ok to use this power injector with a SPA508g? Will it just draw whatever it needs or is that power enjector too much power? I seem some documentation that says the AIR-PSINJSYS1200 will work with a access point that requires less power, but I don't see any other documentation.
