Hello Everyone,
 
This is what Aastra 53i has in user manuel for POE specifications:
 
Power source
— For Ethernet networks that supply in-line power to the phone (IEEE 802.3af)
 
A 48-port switch I am looking at has the following:
 
48-port 10/100 Ethernet Switch, two shared mini-GBIC slots, two Gigabit ports, 
WebView and PoE (Up to 24 ports at 15.4W each or 48 ports at 7.5W each) 
 
What is with the 15.4W and 7.5W? Would that mean only 24 of Aastra 53i at the 
same time? I don't see any specific requirements other than IEEE 802.3af on 
Aastra's manual.
 
Thanks,
Bruce
