Power Connectors

You can provide power to a switch either by using the internal

power supply or the Cisco RPS 300. The connectors are

located at the back of the switch.

Internal Power Supply Connector

• The internal power supply is an autoranging unit

• 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

• Connection for an optional Cisco RPS 300 that uses AC

input and supplies DC output to the switch

• 300-watt redundant power system that can support six

external network devices and provides power to one failed

device at a time

• Automatically senses when the internal power supply of a

connected device fails and provides power to the failed

device, preventing loss of network traffic

• When internal power supply has been brought up or

replaced, the RPS 300 automatically stops powering the

device

• Attach only the Cisco RPS 300 (model

PWR300-AC-RPS-N1) to the RPS receptacle

Indicators

• Per-port status LEDs: link integrity, disabled, activity,

speed, and full-duplex indications

• System status LEDs: system, RPS, and bandwidth

utilization indications

Dimensions and Weight (H x W x D)

• Dimensions: 1.72 x 17.5 x 9.52 in. (4.36 x 44.45 x 24.18

cm)

• One rack-unit (RU) high (1.72 in./4.36 cm)

• Weight: 6.5 lbs (3.0 kg)
