Avaya VSP 7200 Series Installing Manual page 25

The VSP 7254XTQ comes with an 800 W AC power supply and you can install a secondary power
supply for redundancy.
Important:
You must have either a power supply or a power supply cover in each bay to ensure proper
ventilation. Leaving a power supply bay unpopulated or uncovered impairs the ability of the fans
to cool the chassis.
Figure 4: AC power supply
The 800 W AC power supply uses an IEC 60320 C14 AC power cord connector. The AC power cord
is in close proximity to the hot air exhaust, and supports high operating temperatures.
The following table describes the regulatory AC power specifications for the VSP 7200 Series
switches. Note that regulatory power specifications are based on the maximum rated capacity of the
power supplies and are not based on typical power consumption, which is typically lower.
