● 10BASE-T ports: RJ-45 connectors, 2-pair Category 3 (Cat-3), 4, or 5 unshielded twisted-pair
Connectors
and Cabling
(UTP) cabling
● 100BASE-TX ports: RJ-45 connectors, 2-pair Cat-5 UTP cabling
● 100BASE-FX ports: MT-RJ connectors, 50/125 or 62.5/125 micron multimode fiber

mode, or multimode fiber)
● 10GBASE-ER XENPAK-based port (single-mode)
● 10GBASE-LR XENPAK-based port (single-mode)
● Cisco StackWise stacking ports: copper-based Cisco StackWise cabling that is also
compatible with the StackWise Plus technology in the Cisco Catalyst 3750-E Series
Switches.
● Management console port: RJ-45-to-DB9 cable for PC connections
● Customers can provide power to a switch by using either the internal power supply or a
Power Connectors
redundant power system (Cisco RPS 2300 or the Cisco RPS 675). The connectors are
located at the back of the switch.
● Internal power supply connector
● The internal power supply is an autoranging unit.
● The internal power supply supports input voltages between 100 and 240VAC.
● Use the supplied AC power cord to connect the AC power connector to an AC power outlet.
● Cisco RPS Connector
● The connector offers connection for an optional Cisco RPS 2300 or RPS 675 that uses AC
input and supplies DC output to the switch.
● The connector automatically senses when the internal power supply of a connected device
fails and provides power to the failed device, preventing loss of network traffic.
● Only the Cisco RPS 2300 (model PWR-RPS2300) or the Cisco RPS 675 (PWR675-AC-RPS-
N1=) should be attached to the redundant-power-supply receptacle.
Indicators
● Per-port status LEDs: link integrity, disabled, activity, speed, and full-duplex indications
● System-status LEDs: system, RPS, and bandwidth-utilization indications
