10 Gigabit Ethernet Uplinks and the Cisco TwinGig Small Form-Factor Pluggable Converter
The 2350 Series switches feature wire-speed 10 Gigabit Ethernet uplink ports for high-bandwidth
applications, relieving congestion and helping ensure smooth delivery of data. The TwinGig
converter (see Figure 2) converts a 10 Gigabit Ethernet X2 interface into two Gigabit Ethernet
Small Form-Factor Pluggable (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
Cisco Catalyst 2350 Series switches have one power supply slot and support the following power
supplies:
●
C3K-PWR-265WAC: 265WAC power supply
●
C3K-PWR-265WDC: 265WDC power supply
Primary Features and Benefits
Ease of Use in Deployment
Ease-of-use features include:
●
Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches
through a boot server eases switch deployment.
●
Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to
optimize bandwidth.
●
Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all switch
ports.
●
Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel
groups or Gigabit EtherChannel groups to link to another switch, router, or server.
●
Automatic, media-dependent interface crossover (MDIX) automatically adjusts transmit and
receive pairs if an incorrect cable type (crossover or straight-through) is installed.
