10/100 802.3af LAN Ports (CXi II)

The CXi II includes a 16-port managed Layer 2 Ethernet switch. Each port supports auto-negotiation and
is able to connect to 10Base-T or 100Base-TX devices and determine the appropriate data rate from infor-
mation provided to it. Duplex mode and flow control are also programmable for each port. The ports use
8-way RJ-45 connectors that conform to Category 5 wiring standards. Although CAT5 cabling is recom-
mended, Category 3 can be used for limited installations. Refer to Appendix A and the Engineering Guide-
lines for CAT3 Cabling details.
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 CXi II Specific
Guidelines in the Engineering Guidelines document.
