populated Cisco Catalyst 4510R with two 20A and one 15A circuits rather than a

Each system component has an EEPROM that identifies it to the supervisor
engine over a serial connection on the backplane, which also passes along
information like temperature, fan speed, power draw per slot and port, and port
activity. LED status information is also sent to the supervisor engine, which
makes it available to an administrator through a terminal connection or
management software.
All Catalyst 4500 series switches support:
Hardware-based multicast-Protocol Independent Multicast (PIM).
