Cisco 3750 Comparison, 3750 V2,
3750-E, and 3750-X
Cisco 3750 series
• We know that Cisco 3750 series is a kind of stackable, environmentallyfriendly 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.
Comparison Chart for 3750 V2, 3750-E,
and 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 – I’m
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. Wouldn’t 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 don’t 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. I’ve 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.
