Cisco Systems OL-8122-01 SFP Module Slots, LEDs, Setup Button, Cisco Redundant Power Supply RPS

Chapter 1 Introduction

Features and Benefits

10/100-Mbps Fast Ethernet Ports

10/100/1000-Mbps Gigabit Ethernet Ports

•Autosensing (autonegotiation) of port speed and autonegotiating of duplex mode optimizes port bandwidth.

•Automatic-medium-dependent interface crossover (auto-MDIX) capability automatically detects the required cable connection type (straight-through or crossover) and configures the connection appropriately.

PoE-Capable Ports (Available only on the Catalyst Express 500-24LC and Catalyst Express 500-24PC switches.)

•Up to 15.4 W of power provided to connected Cisco prestandard and IEEE 802.3af-compliant powered devices if the switch detects that there is no power on the circuit.

SFP Module Slots

•Fiber-optic SFP modules provide cable media and distance options for switch connectivity. A list of supported Cisco SFP modules is in the “Supported Hardware” section on page 1-13.

LEDs

•System LEDs show switch status, problem detection, PoE usage, and setup status.

•Port LEDs show port status. From the device manager GUI, port LEDs also show duplex mode, speed, and PoE status.

•RPS LED shows status of an installed Cisco redundant power supply (RPS). (Available only on the Catalyst Express 500-24PC model.)

Setup Button

•Button starts the Express Setup program.

Cisco Redundant Power Supply (RPS)

•Cisco redundant power supply (RPS) enhances power reliability. A list of supported RPS models is in the “Supported Hardware” section on page 1-13. (Available only on the Catalyst

Express 500-24PC model.)

Security Slots

•Slots to attach a security cable to the switch.
