I know someone who is running 48 Linksys SPA942 phones off of that switch.

Hello,

That would the cabling from the server room to the wall jacks and to the cubicles. The place doesn't have walls. I can do the cabling too. So, very flexible. Do you know if all the 48 phones will fire up? Linksys Switch has 15.5W per port if only 24 port is used. It has 7.7W if all ports are used for POE.

Thanks
