Cabletron Systems 2H23-50R, 2H33-37R manual

Overview

The 2H23-50R is a high speed network repeater/switch device that provides four Ethernet networks and four Fast Ethernet networks (RJ21 MicroLANs, CONN 1 through CONN 4) and two slots (5 and 6) for optional Fast Ethernet Interface Modules. The RJ21 connectors each consist of 12 repeater ports that are able to reside on the Ethernet

(10 Mbps) or the Fast Ethernet (100 Mbps) network. Each Ethernet and Fast Ethernet network supports 802.1D switching (bridging), Cabletron Systems SecureFast Switching Virtual Network technology and IEEE 802.1Q Port Based Virtual Local Area Networks (VLANs). Slots 5 and 6 support Fast Ethernet Interface Modules to provide uplinks to 100BASE-TX or 100BASE-FX Fast Ethernet Networks.

The 2H33-37R is a high speed network repeater/switch device that provides three Ethernet networks and three Fast Ethernet networks (RJ21 MicroLANs, CONN 1 through CONN 3) and one slot for an optional High Speed Interface Module (HSIM). The RJ21 connectors each consist of 12 repeater ports that are able to reside on the Ethernet (10 Mbps) or the Fast Ethernet (100 Mbps) network. Each Ethernet and Fast Ethernet network supports 802.1D switching (bridging), Cabletron Systems SecureFast Switching Virtual Network technology and IEEE 802.1Q Port Based Virtual Local Area Networks (VLANs). The 2H33-37R can be equipped with an optional HSIM to provide additional connectivity to other high speed networking technologies such as Asynchronous Transfer Mode (ATM), Fiber Distributed Data Interface (FDDI), and Wide Area Network (WAN).

The device may be used as a tabletop unit or can be installed in a standard 19-inch rack using the supplied rack mounting hardware.

The 2H23-50R and 2H33-37R have two power supplies with automatic voltage sensing that allows operation using 100–125 or 200–240 Vac, 50/60 Hz. The power supplies load share 50% (+/-5%) of the power required by the device. If one power supply fails, the remaining power supply assumes the entire load of the device without interruption to network traffic. Each power supply module supports its own ac input connection, which allows the user to connect each power supply to a different ac power circuit.
