2M46-04R Overview
2M46-04R/2M46-04RDC User’s Guide 1-3
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.
1.3.1 Connectivity
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.
1.3.2 Full 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.
