Power Over Ethernet
The CXi controller’s Layer 2 switch can provide 120 Watts of power to
802.3af-compliant devices according to the following general rules:
• Up to 16 IP Phones are supported
• Up to four PKMs (PKM12 or PKM48) are supported on Dual Mode IP
phones. Only one PKM can be attached to a set. Multiple PKMs on a
set require an AC adapter.
• Conference units require an AC adapter.
• Port 1 has the highest priority, port 16 the lowest. If the power budget
is exceeded, power will be turned off to the ports, starting with port 16
and ending with port 1, until less than 120 Watts is being consumed.
