1.9.1 Powering the desk phone
The phone can be powered either via a power adapter (5V/3A - sold separately), via Power over
Ethernet (PoE) or Power over Digital Line (PoDL). The power adapter is sold separately. The power
adapter can be connected to a USB-C connector (connector: 1).
1.9.2 Power Boost
The Power Boost enables the desk phone to provide more USB power (to power an expansion
module, for example) when it is powered via Power over Ethernet (PoE) or Power over Digital Line
(PoDL).
Power Boost is enabled:
• When the desk phone is powered via 5V 3A USB-C PD power adapter.
• When the desk phone is powered by PoE/PoDL, the administrator must ensure that the
PoE/PoDL switch delivers the equivalent of Class 3 power on the port before enabling Power
Boost on the system side. The desk phone needs to be restarted for any changes to take
effect. The management of the USB current limiter is adjusted to increase the available power.
Contact your administrator if necessary.
