conserves energy with customized policies. Together, Cisco EnergyWise technology and Cisco Catalyst switches
reduce greenhouse gas (GhG) emissions and increase energy cost savings and sustainable business behavior.
Sustainability features in the Cisco Catalyst 2960-S and 2960 Series Switches include the following features sets:
●
Cisco EnergyWise technology
●
Efficient switch operation
●
Intelligent power management
Cisco EnergyWise Technology
Cisco EnergyWise is an innovative architecture, added to fixed-configuration switches, promoting companywide
sustainability by reducing energy consumption across an entire corporate infrastructure and affecting more than 50
percent of global greenhouse gas emissions created by worldwide building infrastructure, a much greater effect than
the 2 percent generated by the IT industry. Cisco EnergyWise enables companies to measure the power
consumption of network infrastructure and network-attached devices and manage power consumption with specific
policies, reducing power consumption to realize increased cost savings, potentially affecting any powered device.
EnergyWise encompasses a highly intelligent network-based approach to communicate messages that measure
and control energy between network devices and endpoints. The network discovers Cisco EnergyWise-manageable
devices, monitors their power consumption, and takes action based on business rules to reduce power consumption.
EnergyWise uses a unique domain-naming system to query and summarize information from large sets of devices,
making it simpler than traditional network management capabilities. Cisco EnergyWise’s management interfaces
allow facilities and network management applications to communicate with endpoints and each other using the
network as a unifying fabric. The management interface uses standard Simple Network Management Protocol
(SNMP) or TCP to integrate Cisco and third-party management systems.
Efficient Switch Operation
Cisco Catalyst 2960-S and 2960 Series Switches, designed and engineered by Cisco, provide optimum power
saving, low power operations for industry best-in-class power management, and power consumption capabilities.
The Cisco Catalyst 2960-S ports are capable of reduced power modes so that ports not in use can move into a lower
power utilization state.
Intelligent Power Over Ethernet Management
The Cisco Catalyst 2960 Series PoE models support the latest PoE devices including Cisco IP phones and Cisco
Aironet
®
WLAN access points, providing up to 15.4W of power per port, as well as any IEEE 802.3af-compliant end
device.
●
Per Port Power Consumption command allows customers to specify maximum power setting on an
individual port
●
Cisco Discovery Protocol Version 2 allows switches to negotiate a more granular power setting when
connecting to a Cisco powered device such as IP phones or access points than what is provided by IEEE
classification
●
PoE MIB provides proactive visibility into power usage and allows customers to set different power-level
thresholds
●
IEEE 802.3af and Cisco Prestandard PoE support comes with automatic discovery to detect a Cisco
prestandard or IEEE 802.3af endpoint and provide the necessary power without any user configuration. Per-
port PoE power sensing measures the actual power being drawn, enabling more intelligent control of
powered devices.
