Witam serdecznie na mojej aukcji!

Dziś mam do zaoferowania zarządzalnego switcha Longshine LCS-883R-SW2400 10/100Mbps.

Jest to świetna konstrukcja, która w moim przypadku, świetnie sprawdziła się w mojej sieci.
Switch posiada VLAN-y, Port Trunking, możliwość podłączenia dodatkowego modułu fiber (z tyłu).
Z przodu przycisk "MODE" umożliwiający szybie sprawdzenie podstawowych jego funkcji bez konieczności łączenia się z nim.
Zarządzanie odbywa się poprzez kabel null modem rs232.

Z najważniejszych rzeczy: wymieniłem chłodzenie w switchu bo zaczęły już trochę hałasować.
Zostały zamontowane dwa solidne SUNON-y na łożysku kulowym (VAPO). Switch przepracował na nich
kilkanaście dni (nawet się nie zakurzyły).
Rackowe kątowniki są zamontowane.
Dokładam gratis kabel zasilający.

Poniżej przedstawiam dokładny opis w języku angielskim:

This device is a powerful, high-performance Fast Ethernet switching hub, with all 24 ports capable of 10 or 100Mbps auto-negotiation operation (NWay) which means the switch can automatically negotiate with the connected partners on the network speed and duplex. It is ideal for micro-segmenting large networks into smaller and connected subnets for improving the performance of the bandwidth demanding multimedia and imaging applications. Moreover, the 10/100Mbps auto-sensing ability provides an easy way to migrate
10Mbps to 100Mbps networks with no pain. With port trunking and vLAN enhanced features, users can build up 800Mbps fat pipe between switch and switch connection that will boost the backbone bandwidth and get rid of network looping issue. The vLAN function can separate the network traffic into groups that could provide more network security and prevent the broadcast packet impact the network performance.
The switch supports the rich diagnostic LEDs and two status button on the front-panel for providing the operating status and configuration of individual port and whole system. Moreover, the RS232 console port could be used to easily configure the switch status. Plug and play is the most important concept of the system design, users just need to plug the cable and turn on the power then the system could work under all kinds of network protocols.
