Typical Network Configurations
The MXe and AX do not support PoE. The phones need to be powered
from an adapter or power brick, or from a powered Ethernet
connection. A variety of L2 switches provide PoE.
Category 5 cable is required for the uplink connection between the
expansion switches and the CXi/CXi II/MXe/AX, and is recommended
for all other Ethernet connections. Category 3 cable can be used to
connect single IP Phones directly to the expansion switches or to the
Layer 2 switch of the CXi/CXi II.
L2 switches for voice-only networks do not require VLAN capability.
Voice and Data Networks
You can connect additional IP phones to the AX, MXe and CXi/CXi II
controllers. Use one or two switches connected in a daisy chain. The L2
switches connect to the Ethernet ports or to the controller.

Note:The expansion switches must be manageable and must adhere to the
802.1p/Q VLAN standard.
