Introduction

Introduction to Industrial Managed Switch

Welotec’s RSAES series are product lines of powerful industrial managed switch which are referred to as Open Systems Interconnection (OSI) Layer 2 bridging devices. Unlike an “unmanaged” switch, which is normally found in homes or in Small Office/Home Office (SOHO) environments and runs in “auto-negotiation” mode, each port on a “managed switch” can be configured for its link bandwidth, priority, security, and duplex settings. The managed switches can be managed by Simple Network Management Protocol (SNMP) software, web browsers, Telnet, or serial console. Since every single port can be configured to specific settings, network administrators can better control the network and maximize network functionality.

Welotec’s managed switch is also an industrial switch and not a commercial switch. A commercial switch simply works in a comfortable office environment. However, an industrial switch is designed to perform in harsh industrial environments, i.e., extreme temperature, high humidity, dusty air, potential high impact, or the presence of potentially high static charges. Welotec’s managed switch works fine even in these environments.

Welotec’s managed switch is designed to provide faster, secure, and more stable network. Advantages that make it a powerful switch are that it supports security such as IP Source Guard, DHCP Snooping, ARP Inspection as well as Access Control List (ACL) and network redundancy protocols/technologies such as Ethernet Ring Protection Switching (ERPS), Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP). These protocols provide better network reliability and decrease recovery time.

Welotec’s managed switch supports a wide range of IEEE standard protocols. This switch is excellent for keeping systems running smoothly, reliable for preventing system damage or losses, and friendly to all levels of users. The goal of this innovative product is to bring users an enhanced network management experience.

Introduction to the Document

There are total of five sections in this document: Introduction, Configuration, Monitor, Diagnostics, Maintenance. The first section introduces the device, the software features, and the document. The second section, configuration shows users the setting webpage and the meaning of each parameter. The third section, Monitor, allows user to see the current status of the device. The forth section, Diagnostics, allows user to identify problems and troubleshooting through ping and traceroute webpage. Lastly, the fifth section, Maintenance, will let user to restart the device, reset all settings to the default values, as well as, upload software version and save/download/upload/activate/delete the current configuration.
