Power Requirements

When preparing your site for the switch installation, follow these requirements:
• When installing two power supplies, connect each power supply to a separate input power source. If
• To prevent a loss of input power, be sure that the total maximum load on each source circuit is within
• You might decide to use an uninterruptible power supply (UPS) to protect against power failures at your
• The AC-input power supply has a detachable power cord that allows you to connect each power supply
• You can connect the DC-input power supply to the power source with heavy-gauge wiring connected
• If you are using a 200/240 VAC power source in North America, the circuit must be protected by a
• The source AC outlet must be within 6 feet (1.8 meters) of the system and should be easily accessible.

unstable when operating with the Catalyst 6880-X switch power supplies which use power factor
correction (PFC). This can cause the output voltage waveform to the switch to become distorted resulting
in an undervoltage situation in the system.
