Introduction
Product Description
The RLH Managed Ethernet Switch is a smart managed switch that offers 16 10/100Base-T(x) RJ-45 TCP
ports together with 8 100Base- FX fiber connectors. The optical interfaces may be dual fiber single mode or
multimode, or bi-directional single fiber, and have a transmission up to 120Km/74 miles.
The switch can be managed through it’s imbedded Web Interface, with simplified settings accessible through
the console port, and also supports external alarm functions for alarm input monitor purposes. It supports
Port based VLAN and IEEE802.1Q VLAN, VLAN groups and VLAN IDs can be created. It also supports
Broadcast storm control, Port bandwidth control, QOS, etc.
The switch may be used to establish SW-Ring for accomplishing redundancy for an Ethernet ring network
topology. The intelligent redundancy system has a short self-recovery time for automatic recovery of the
network section.
The RLH Managed Ethernet Switch uses only 1RU and comes complete with EIA19” rack ears for rack mount
applications, or it may be used on a desktop or shelf. The fiber optic ports allow for Ethernet network
extension over long distances, and fiber optic cable provides electrical isolation between devices. It is ideal
for institutional use, medium/small enterprises and intelligent community networks that need to
accommodate various services such as video, VOIP and high speed data over fiber.
The RLH 16+8 Ethernet Switch comes complete with an internal 115/220VAC power supply, and is covered
by a 5 year warranty.
