Cisco 3750 series

• We know that Cisco 3750 series is a kind of
  stackable, environmentally-friendly switch that
  improves LAN operating efficiency and offer the
  highest resiliency. Also we are clear that the
  Cisco Catalyst 3750 v2 Series are next-generation
  energy-efficient Layer 3 Fast Ethernet stackable
  switches. These new switches support Cisco
  EnergyWise technology, which helps you manage the
  power consumption of your network, thereby
  reducing energy costs and carbon footprint. And
  the Cisco Catalyst 3750 v2 Series consumes less
  power than its predecessors and is an ideal
  access layer for enterprise, retail, and branch
  environments. It helps increase productivity and
  protects your network investment by providing a
  unified network for data, voice, and video.
• What are the MAIN differences between the lines
  of Cisco 3750 series switches? Now we list a
  brief overview of the biggest differences between
  the Cisco 3750 V2, Catalyst 3750-E, and the Cisco
  3750-X.

• 10/100/1000 Port Availability
• The Cisco 3750V2 series does not have a
  10/100/1000 model. All port configurations are
  either 24-port 10/100 or 48-port 10/100. Gigabit
  is only offered through 2 or 4 SFP ports. Perhaps
  backplane speed or forwarding rate made Cisco
  make a u-turn on this Im not sure. The 3750V1
  series offered a wide variety of 10/100/1000 port
  options. If you want 10/100/1000 port density
  then skips over the 3750V2 series and go with the
  3750-E or 3750-x series.

• Cisco StackPower
• Cisco StackPower combines all the individual
  power supplies installed in the switches and
  creates a pool of power, directing that power
  where it is needed. Up to four switches can be
  configured in a StackPower stack. StackPower
  cables use their own special cables and connect
  in the same way as the popular StackWise cables.

IEEE 802.3af IEEE 802.3at

• Cisco supports this across all 3750 platforms
  that have PoE capabilities. 802.3at provides 30W
  of power per port. Wow. Soon we will power far
  more than just IP phones and wireless access
  points. Wouldnt it be cool to charge your smart
  phone or tablet over an available Ethernet port?
  Just always keep in mind as you rely more on PoE
  you need to put more thought into power
  consumption, backup power, and additional cooling
  in your data closets. Typically this is the most
  forgotten area when deploying PoE technology such
  as IP phones. You dont want those switches
  sitting on a power strip when 24 or more end
  users are relying on that switch to power their
  phones.

• Dual Redundant Power Module Supplies
• The 3750-X supports two hot swappable power
  supplies. The switch ships with one power supply
  by default. The second power supply can be
  purchased at the time of the order or later. Ive
  found that in 3750-X stacks going with one power
  supply works great when combined with StackPower.
  It saves money and reduces power consumption.
•  
• Network Modules
• There are four network modules for the 3750-X.
  Each provides a combination of GbE or 10GbE
  interfaces. For upgrade protection and
  scalability we often find ourselves deploying the
  four port network modules that support either
  four GbE or two 10GbE. This allows a customer to
  utilize existing GbE connectivity and later
  upgrade to 10GbE.
