2M46-04R Overview

The 2M46-04R is a tabletop unit that can be installed in a standard 19-inch rack using the supplied rack mounting hardware.

The 2M46-04R has two ac power supplies. 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.

The 2M46-04RDC operates from two dc voltage power sources. 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 dc input connection, which allows the user to connect each power supply to a different dc power source.

1.3.1Connectivity

The 2M46-04R has two front panel slots (ports 1 and 2) for optional Fast Ethernet Interface Modules to support an uplink to 100 Mbps Fast Ethernet backbones or a high speed connection to a local server. There are also two HSIM slots for optional HSIMs to provide additional connectivity to various networking technologies.

1.3.2Full Duplex Switched Ethernet

The optional Fast Ethernet Interface Modules can be configured to operate in Full Duplex Switched Ethernet (FDSE) mode which provides up to 200 Mbps of throughput per interface.
