Tabulate the power requirements for the module(s) to be added. For example, let’s say that the
following module is to be added to the chassis:
•
OS7-GNI-U12 (48 watts)
As shown, the total power required for the incoming module is 48 watts. If the module is installed, the
switch’s power budget will be exceeded by
at least 8 watts
. The module
will not
be power on until:
•
One or more modules are removed from the chassis and the switch is rebooted
or
•
An additional power supply is added (if applicable) and the switch is rebooted
