Seagate KSD-541-P manual Introduction, Plug and Play, Fiber Connectivity, Power over Ethernet

1. Introduction

The switches are 5-port Fast Ethernet switches which are featured with four copper ports and one combo port. The combo port comes with one RJ-45 and one SFP slot. The SFP slot can be mounted with a fiber transceiver optionally to support a fiber connection.

For more coming PoE (Power Over Ethernet) applications, the PoE switch model is equipped with PoE design in four copper ports. With proper 48VDC power supply, it is able to deliver power to four PoE PD devices via Cat.5 cables. This guide describes the installation information about two models as follows:

Basic Model Industrial 5-port Fast Ethernet switch with SFP slot

PoE Model Industrial 5-port Fast Ethernet switch with SFP slot and PoE feature

In summary, the switch provides the following advantages:

Plug and Play

No configuration is required in using the switch. With the featured auto-negotiation function, the switch can detect and configure the connection speed and duplex automatically. The switch also provides auto MDI/MDI-X function, which can detect the connected cable and switch the transmission wire pair and receiving pair automatically. This auto-crossover function can simplify the type of network cables used.

Fiber Connectivity

For fiber connection, the SFP slot can be installed with an optional SFP optical fiber transceiver to support one fiber connection when needed.

Power over Ethernet

For PoE applications, four IEEE 802.3af-compliant PoE PSE ports are provided in four copper ports. Each PSE port can deliver +48VDC power to one PoE PD (Powered Device) via the connected Cat.5 cable.

Industrial Features

For industrial environment, the devices are designed with the following enhanced features exceeding that of commercial Ethernet switches:

•High and wide operating Temperature

•Power input interface: Industrial screw terminal block and DC power jack for external commercial power adapter as option

•Screw panel and DIN rail mounting support for industrial enclosure

•Industrial-rated Emission and Immunity performance
