HAPTER
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.
•
Class 1, 2, and 3 devices receive 4, 7, and 13 Watts, respectively. Unclassified (Class 0) devices are
•
budgeted 7.5 Watts by the PoE subsystem, but can receive up to 13 Watts depending on need.
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.
For information on planning PoE installation and detailed information on the CXi II IEEE 802.3af PoE
capability, refer to the Engineering Guidelines.

3300 Power Dongle (Cisco compliant)

: The dongle is specifically designed to connect Mitel desktop appliances to Cisco power equip-

ment. Do not connect equipment other than Mitel desktop appliances to the dongle.
: Telephone firmware must be at Release 3.2 or higher before the phone can be powered from a
CAUTION
Cisco switch or hub through the 3300 Power Dongle. Power the set from a wall plug to update the firm-
ware, and then connect the dongle BEFORE unplugging the phone from the wall.
: When power is supplied by Cisco equipment to the Mitel desktop appliance, the Ethernet cable
CAUTION
must run directly from the Cisco equipment supplying the power to the 3300 Power Dongle
(Cisco-compliant). The dongle will be directly connected to the Mitel desktop appliance.
The 3300 Power Dongle (Cisco-compliant) provides MiVoice IP Phones with LAN power from Cisco hubs
that do not comply with the IEEE 802.3af Standard.
There are two versions available:
3300 Power Dongle (p/n 50002922) Rev1—allows MiVoice IP Phones to be powered by the Cisco

3524 and 6000 series of products or the Cisco WS-PWR-PANEL
3300 Power Dongle (p/n 50003734) Rev2—allows MiVoice IP Phones to be powered by the Cisco
•
3524, 3550, 4000 and 6000 series of products or the Cisco WS-PWR-PANEL.
The dongle provides signaling to the Cisco hub or the Cisco Power Panel to provide power on the
Ethernet line.

The information in this section is believed to be accurate but is not warranted by Mitel. Please refer to
Cisco documentation for specific power limits.
Cisco end-span power/data hubs include the Cisco 3524, 3550, 4000, and 6000 series of products. The
Cisco WS-PWR-PANEL is a mid-span power hub. These hubs all have the capability to power the
following MiVoice IP Phones: 5001 IP Phone, 5005 IP Phone, 5010 IP Phone, 5020 IP Phone, 5140 IP
Appliance, 5207 IP Phone, 5215 IP Phone, 5220 IP Phone, and 5240 IP Phone.
The WS-PWR-PANEL is electrically located between a conventional data hub and the powered device.
This unit passes the data pairs through from the data hub to the terminal device while inserting power on
the spare pairs (4/5 and 7/8).
Before enabling port power, this unit generates a signal that a power-ready device will loop back. This
signal is transmitted on the 7/8 pair and if this is looped back on the 4/5 pair, the hub then assumes a
power-ready device is connected and enables power on that port. The hub continuously probes the port
