Power Requirements

Catalyst 6513 Switch Internal Airflow
Power Requirements
Follow these requirements when preparing your site for the switch installation:
In systems configured with two power supplies, connect each of the two power supplies to a separate
input power source. If you fail to do this, your system might be susceptible to total power failure
due to a fault in the external wiring or a tripped circuit breaker.
To prevent a loss of input power, be sure that the total maximum load on each source circuit is within
the current ratings of the wiring and breakers.
In some systems, you may elect use an uninterruptible power supply (UPS) to protect against power
failures at your site. Please be aware when selecting a UPS that some UPS models that use
ferroresonant technology can become unstable when operating with the Catalyst 6500 series 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.
The AC-input power supply has a detachable power cord (except for the 4000 W power supplies)
that allows you to connect each power supply to the site power source. The 4000 W AC-input power
supply power cords are hard-wired to the power supply and cannot be removed.
