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.
