FAQ
What Cisco phone models is this adapter compatible with?
The Cisco CP-PWR-CUBE-3-RF AC adapter is specifically designed for and compatible with Cisco Unified 7900 Series IP phones. This includes various models within the 7900 Series lineup that require 48V DC power input for operation and charging.
What input voltages does this power adapter support?
This Cisco adapter supports dual input voltages of 110V AC and 220V AC, making it suitable for use in regions with different electrical standards. This flexibility allows for deployment in North American 110V environments as well as European and other international 220V markets.
What is the output voltage of this AC adapter?
The adapter provides a constant 48V DC output, which is the standard voltage required by Cisco Unified 7900 Series IP phones for proper operation and charging. This stable voltage delivery ensures reliable performance of connected telephony devices.
Does this adapter support different power frequencies?
Yes, the Cisco CP-PWR-CUBE-3-RF supports both 50Hz and 60Hz power frequencies. This frequency compatibility ensures proper operation in regions with different electrical grid standards, including North America (typically 60Hz) and many international locations (typically 50Hz).
Can this adapter be used as a backup power source?
This adapter serves as a primary power source rather than a backup solution. It provides continuous 48V DC power to Cisco Unified 7900 Series IP phones when connected to an AC outlet. For power backup during outages, organizations typically implement UPS systems rather than relying on individual device adapters.
Is this adapter suitable for international business deployments?
Yes, the dual-voltage input (110V/220V AC) and dual-frequency support (50Hz/60Hz) make this adapter well-suited for international business deployments. Organizations with offices in different regions can standardize on this single adapter model rather than sourcing region-specific power supplies for their Cisco Unified 7900 Series IP phones.
