Description Specification

Catalyst 3750G-16TD)

• Configurable maximum transmission unit (MTU) of up to 9000 bytes, with a maximum Ethernet frame size

of 9018 bytes (jumbo frames) for bridging on Gigabit Ethernet ports, and up to 1546 bytes for bridging and

routing on Fast Ethernet ports

Connectors and Cabling

• 10BASE-T ports: RJ-45 connectors, 2-pair Category 3 (Cat-3), 4, or 5 unshielded twisted-pair (UTP)

cabling

• 100BASE-TX ports: RJ-45 connectors, 2-pair Cat-5 UTP cabling

• 1000BASE-T ports: RJ-45 connectors, 2-pair Cat-5 UTP cabling

• 1000BASE-T SFP-based ports: RJ-45 connectors, 2-pair Cat-5 UTP cabling

• 1000BASE-SX, -LX/LH, -ZX, and CWDM SFP-based ports: LC fiber connectors (single-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

• Management console port: RJ-45-to-DB9 cable for PC connections

Power Connectors

• Customers can provide power to a switch by using either the internal power supply 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 240 VAC.

• 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 675 that uses AC input and supplies DC output

to the switch.

• The connector offers a 675W redundant power system (RPS) that supports up to 6 external network devices

and provides power to 1 failed device at a time.

• 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 675 (model 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
