Chassis Power Budget
Checking Chassis Power Before Adding Components
Adding Network Interface (NI) modules and other components, as well as removing power supplies,
significantly affects the overall power budget for the switch. As soon as a component is inserted and the
component’s connectors make contact with the chassis backplane, the additional power requirements take
effect. If there is not adequate power, the incoming component will not power on. Additional power errors
may also occur, which can interrupt data flow on the switch. Therefore, it is important to manually check
the current chassis power before adding a module to verify that the current chassis power supports the
change.
Use the show chassis command to determine available power budget.
