Hi every one ...I wanted to know why my switch network (has poe) not provide power to my ip camer that has poe option but when I connected my ip camera to switch it didn't power on..I connected my ip camer by single poe injector to ip camer and then ip camera turn on...what is going wrong
Thanks in advance..
Consider running a new, working patch cable wired to T-568B spec on both ends OR T-568A spec on both ends from switch to camera to bypass your "extender connector". The POE injector works possibly because it is passive or Mode B (pins 4/5 for positive DC and pins 7/8 for negative DC ) and the switch's POE scheme is a different mode, such as Mode A where power is on pins 1/2 for positive DC and pins 3/6 for negative DC. It's also possible there is an issue with the cable you said you "...cut in middle of path and I used extender connector."
