2H28-08R Overview
The 2H28-08R may be used as a tabletop unit or can be installed in a standard 19-inch rack using the supplied rack mounting hardware.
The 2H28-08R has two power supplies. Both are universal ac 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.
1.3.1Connectivity
The six fixed ports on the 2H28-08R connect to Ethernet networks or workstations using SC fiber optic connectors.
The 2H28-08R has two front panel slots (ports 7 and 8) for optional Fast Ethernet Interface Modules to support an uplink to 100 Mbps Fast Ethernet backbones, a high speed connection to a local server, or a connection to 10BASE-T.
1.3.2Switching Options
The 2H28-08R provides traditional switching (IEEE 802.1D bridging), IEEE 802.1Q, or SecureFast Switching Virtual Network Services between all of the front panel interfaces including the optional Fast Ethernet Interface Modules. SecureFast Switching and IEEE 802.1Q allow for migration to Virtual Network technologies without requiring the replacement of existing equipment.
1.3.3Full Duplex Switched Ethernet
All the ports for the 2H28-08R, including the optional modules, can be configured to operate in Full Duplex Switched Ethernet mode, which provides 200 Mbps of throughput.
