Remote power
As mentioned earlier in this document, there are three communication standards that phones
can use to advertise their power requirements to an Ethernet switch that supports a PoE
mechanism. In all cases, both the phone and the powered Ethernet switch must comply with
the same standard. The three standards are:
• Cisco Discovery Protocol (CDP)
• IEEE 802.3af Power Over Ethernet Standard (PoE)
• IEEE 802.3ab Link layer Discovery Protocol (LLDP-MED).
CDP power advertisements
Table 35 can be used to determine which CDP power advertisement a phone will use.
When using PoE to provide power to the phones, consult the data sheet for the mid-span hub
or the powered Ethernet switch to determine the maximum power supply capabilities of the
powered Ethernet switch or the mid-span hub.
5560 IPT 12.9
Bluetooth Module for use with 5330, 5340 and 5360. 3.0
UC360 The UC360 can consume up
to 25.5 Watts, however
typical power consumption is
less. For details refer to the
UC360 Engineering
Guidelines.
Note 1: See “Power Restrictions” on page 67. for information about power restrictions related to the Gigabit
Ethernet Phone Stand.
Note 2: The power consumed by this device adds to the power consumption of the phone it is
attached to.
Note 3: The Programmable Key Modules (PKM) are available in two different models, the 5412 and the 5448.
In situations where the PKMs are powered via PoE the installer must add the PKM power consumption and the
phone power consumption together to determine the total power consumption.
Note 4: The 5360 will draw 9.2 Watts when it is in Gigabit Ethernet mode and 7.9 Watts when in 10/100 Mb/s
mode.
Note: The CXi and CXi II only support the IEEE 802.3af PoE standard.
Note: Depending on the particular PoE protocol used, the phone may advertise a power
requirement that is different from the actual phone power consumption shown in
Table 34. Any differences between advertised values and actual values is intentional to
ensure correct interworking with the PoE protocol.
