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 SNMP or SSL to integrate Cisco and third-
party management systems.
Cisco EnergyWise extends the network as a platform for power control plane for gathering, managing, and reducing
power consumption of all devices, resulting in companywide optimized power delivery and reduced energy costs.
10 Gigabit Ethernet Uplinks and the Cisco TwinGig SFP Converter
The Cisco Catalyst 3750-E features wire-speed 10 Gigabit Ethernet uplink ports for high-bandwidth applications,
relieving congestion and helping ensure smooth delivery of data. The TwinGig SFP converter (see Figure 2) converts
a 10 Gigabit Ethernet X2 interface into two Gigabit Ethernet SFP ports. This way, customers can initially use the
switch with Gigabit Ethernet uplinks and later implement 10 Gigabit Ethernet uplinks as business demands change,
without having to upgrade the access layer.

Modular Power Supplies
The Cisco Catalyst 3750-E Series Switches have one power supply slot and support the following power supplies.
PoE switches require a PoE power supply. Data-only switches can operate with any of the power supplies.
●
C3K-PWR-1150WAC: 1150WAC power supply with 800W PoE
●
C3K-PWR-750WAC: 750WAC power supply for 24-port switch with 420W PoE
●
C3K-PWR-265WAC: 265WAC power supply for 48-port or 24-port switch without PoE
●
C3K-PWR-265WDC: 265WDC power supply for 48-port or 24-port switch without PoE
Maximum power availability for converged voice and data networks is attainable when a Cisco Catalyst 3750-E
Series Switch is combined with the Cisco RPS 2300 Redundant Power System for transparent protection against
internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power
outages. Using the RPS 2300 to provide backup power, the Cisco Catalyst 3750-E Series Switch power supplies
become hot swappable. Table 3 shows the power supply compatibility matrix.
