Chapter 1 Overview Front-Panel Description When set for autonegotiation, a port senses the speed and duplex settings of the attached device and advertises its own capabilities. If the attached device supports autonegotiation, the port negotiates the best connection (that is, the fastest line speed that both devices support and full-duplex transmission, if the attached device supports it) and configures itself accordingly.
Chapter 1 Overview Front-Panel Description 100BASE-FX and 1000BASE-SX Ports The 100BASE-FX and 1000BASE-SX ports both use 50/125- or 62.5/125-micron multimode fiber-optic cabling. The 100BASE-FX ports operate only at 100 Mbps in full-duplex mode, and the 1000BASE-SX ports operate only at 1000 Mbps in full-duplex mode. In full-duplex mode, the cable length from a switch to an attached device cannot exceed 1804 feet (550 meters).
Chapter 1 Overview Front-Panel Description • 1000BASE-T GBIC module for copper connections that cannot exceed 328 feet (100 meter). • CWDM GBIC module for single-mode fiber-optic connections that cannot exceed 393,719 feet (120 kilometer). • GigaStack GBIC module for creating a 1-Gbps stack configuration of up to nine supported switches.

Chapter 1 Overview Management Options Cisco RPS Connector The RPS is a 300W redundant power system that can support six external network devices and provides DC power to one failed device at a time. It automatically senses when the internal power supply of a connected device fails and provides power to that device, preventing loss of network traffic. Warning Attach only the Cisco RPS 300 (model PWR300-AC-RPS-N1) to the RPS receptacle.
Chapter 1 Overview Management Options • IOS command-line interface (CLI) You can manage switches by using command-line entries. To access the CLI, connect a PC or terminal directly to the console port on the switch rear panel. If the switch is attached to your network, you can use a Telnet connection to manage the switch from a remote location. For more information, refer to the switch command reference.
C H A P T E R 2 Installation This chapter describes how to install your switch, interpret the power-on self-test (POST), and connect the switch to other devices.

Appendix C Translated Safety Warnings DC Power Disconnection Warning Warnung Avvertenza Advarsel Aviso ¡Advertencia! Varning! Ethernet-Kabel müssen abgeschirmt werden, wenn sie in einer Zentrale eingesetzt werden. I cavi Ethernet devono essere schermati se utilizzati in un ambiente di ufficio centrale. Ethernet-kabler skal være skjermet når de brukes i et sentralt kontormiljø. Os cabos “Ethernet” deverão estar armados quando usados em ambiente de escritório central.
Appendix C Translated Safety Warnings DC Power Disconnection Warning Varoitus Varmista, että tasavirtapiirissä ei ole virtaa ennen seuraavien toimenpiteiden suorittamista. Varmistaaksesi, että virta on KATKAISTU täysin, paikanna tasavirrasta huolehtivassa kojetaulussa sijaitseva suojakytkin, käännä suojakytkin KATKAISTU-asentoon ja teippaa suojakytkimen varsi niin, että se pysyy KATKAISTU-asennossa.
Appendix C Translated Safety Warnings DC Power Disconnection Warning Aviso Antes de executar um dos seguintes procedimentos, certifique-se que desligou a fonte de alimentação de energia do circuito de corrente contínua. Para se assegurar que toda a corrente foi DESLIGADA, localize o disjuntor no painel que serve o circuito de corrente contínua e coloque-o na posição OFF (Desligado), segurando nessa posição a manivela do interruptor do disjuntor com fita isoladora.
Appendix C Translated Safety Warnings Exposed DC Power Wire Warning Exposed DC Power Wire Warning Warning Waarschuwing An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power source wire extends from the terminal block plug. Een blootgestelde verbindingsdraad van een ingangsgelijkstroombron kan gevaarlijke elektriciteitsniveaus geleiden.
Appendix C Translated Safety Warnings Service Personnel Warning Aviso Um fio condutor exposto de uma unidade de entrada de DC (corrente contínua) pode transportar níveis perigosos de electricidade. Certifique-se de que nenhuma secção exposta de um fio condutor da fonte de energia de entrada de DC se extende a partir da ficha da placa de terminais. ¡Advertencia! Un cable desnudo de una fuente de entrada de alimentación de corriente directa (DC) puede conducir niveles de electricidad peligrosos.
