Hardware Technical Reference Manual
The 16 ports comply with the 802.3af Power over Ethernet specification, which enables them
to deliver power to IP phones and other Ethernet devices over Category 3 or 5 cabling. As a
minimum, the PoE module provides enough power for 16 IP phones, some of which may be
fitted with PKMs. For details about PoE and planning a PoE installation, see the Engineering
Guidelines on the Mitel Edocs web site (http://edocs.mitel.com).
The internal switch uses 802.1p/Q VLAN prioritization to ensure the quality of voice calls,
forwarding packets with priority value 6 (from IP phones) ahead of packets with priority value 0
(from PCs and other IP devices). Programming is required only if an expansion switch is
connected. Refer to the CX/CXi-Specific Guidelines in the Engineering Guidelines document.
Features
• Managed switch functions: support for 802.1p/Q prioritization on default VLAN (1)
• Auto-MDIX: automatically adjusts for straight-through or crossover cables on all ports
• Port speed auto negotiation: the port will negotiate with the far end device to select 10Base-T
or 100Base-TX transmission rates and half or full duplex (or manually programmable)
• Flow control: ensures reliable communication during full-duplex operation
