System Architecture
Cisco Catalyst 4500 Series Service Provider DC Power Supply
The triple-input 1400 W DC power supply is optimized for service provider or central-office
deployments. By providing multiple inputs, the service provider DC power supply enables central-office
technicians to customize the output power to meet their application needs. Many central-office
deployments require only a fraction of the 1400 W available in the service provider power supply. Low
current inputs mean technicians can connect the supply to smaller fuses and breakers. The service
provider power supply makes it possible to deploy a Cisco Catalyst 4503-E with a single 15 A circuit.
Likewise, it is possible to deploy a fully populated Cisco Catalyst 4510R-E with two 20 A and one 15 A
circuits rather than a single 60 A connection, which often requires rack rewiring.
Management Flow
Figure 1-18 shows management and status information flow through the system.
Figure 1-18 Management Flow
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 E-series switches support:
• Cisco Group Management Protocol, for standards-based and Cisco technology-enhanced efficient
multimedia networking.
• Simple Network Management Protocol (SNMP).
• CiscoWorks, which can manage critical network characteristics such as availability, responsiveness,
resilience, and security.
• Cisco NetFlow Services. The Cisco NetFlow Services Card for the Supervisor Engine IV and V
support statistics capture in hardware for flow-based and VLAN-based statistics monitoring. This
data can be exported, collected, and analyzed for virus detection and mitigation, network-traffic
accounting, usage-based network billing, network planning, network monitoring, and data-mining
capabilities. Cisco NetFlow Services is integral to the Supervisor Engine V-10GE.
