Cisco Systems 4500 manual Management Flow

Chapter 1 Product Overview

System Architecture

Catalyst 4503 with a single 15A circuit. Likewise, it is possible to deploy a fully populated Cisco Catalyst 4510R with two 20A and one 15A circuits rather than a single 60A connection, which often requires rack rewiring.

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).

•Internet Group Management Protocol (IGMP).
