Historic energy consumption is probably higher than classically POE supported.
Also, any length of POE run gets voltage drop, and POE switches and injectors often have tedious modal configuration based upon length of run and are designed with non-standard limitations such as maximum draw limits shared across multiple ports, which in aggregate will cause no end of issues. For verification, ask any experienced CCTV installer. These are exactly the sort of issues that cause users to take products back to their distributors.
So it's a case of "works in theory, PITA in reality, probable support and brand image impact huge, resulting priority zero".
- JoeAltmaier 3y agoIt's really popular in factories etc, because it reduces cable runs I guess.
- contingencies 3y agoThat's right, but factories have other problems too: especially EMI due to huge loads being switched, which twisted pairs, shielded twisted pair and ethernet termination magnetics are designed to resist. Also, industrial cable routing can get pretty hairy, this means the ability to round a corner at a relatively tight radius can be important. Using standard ethernet cables for low current DC power keeps these concerns generally within acceptable realms of normality.
