Power requirements |
The Cisco Unified IP Conference Phone 8831 is an interoperable IEEE 802.3af PoE (Class 3 device); 48 VDC is required; it can be supplied locally at the desktop using an optional AC-to-DC power supply (CP-PWR-CUBE-3=). Use of the power supply also requires the use of one of the corresponding AC country cords listed in Table 7 later in this document. Use of a power supply (CP-PWR-CUBE-3=) is required when using the Cisco Unified IP Conference Phone 8831 in a daisy-chain configuration. |
