I have purchased the above conference phone from a big supplier in the US. They claim that the power cube compatible with the phone is cp-pwr-cube-4 but this cube does not fit. The vendor seem to be unable to give me the correct fitting cube. I have googled cisco product sheet and there is a mention of a Power cube 3? Is this the compatible one for the conference phone 8831? Please advise!
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.
