Modular Power Supplies
The Cisco Catalyst 3750E-48TD Switch has one power supply slot and supports the following
power supplies.
●
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 3750E-48TD 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 3750E-48TD Switch power supply becomes hot swappable. Table 4 shows the
power supply compatibility matrix.
Redundant Power System
The Cisco Catalyst 3750-E Series Switches support the new generation of Redundant Power
Supply (RPS) 2300. The RPS 2300 increases availability in a converged data, voice, and video
network by providing transparent power backup to two of six attached Cisco Catalyst 3750-E Series
Switches at the same time. The failed power supply can be swapped out while the switch is being
powered up by the RPS 2300.
Primary Features and Benefits
Ease of Use: Deployment
A working stack is self-managing and self-configuring. When switches are added or removed, the
master switch automatically loads the Cisco IOS Software version running on the stack to the new
switch, loads the global configuration parameters, and updates all the routing tables to reflect
changes. Upgrades are applied universally and simultaneously to all members of the stack.
The Cisco Catalyst 3750-E Series stacks up to nine switches as a single logical unit for a total of
468 Ethernet 10/100/1000 ports or 18 10 Gigabit Ethernet ports. Individual 10/100/1000 units can
be joined in any combination to evolve with network needs.
Other ease of use features include but are not limited to:
●
Smartports enable fast and easy configuration of Cisco recommended best practice security
and QoS features, encapsulating years of Cisco networking expertise.
