INTRODUCTION
General Description
The Magnum Blade DS12 & DS12E compact cPCI Hubs are
designed to I/O slot for a simple solution to cPCI Ethernet system problems.
This eliminates the need for a hub in a separate box. The reliable Magnum
Blade hubs provide efficient slot utilization in a 6U X 4HP-cPCI form factor
with no cPCI Backplane connections used. They can be used in practically
any cPCI system, without design modifications.
The Magnum Blade DS12 Dual speed cPCI hub has 12 RJ-45 ports,
each 10/100Mbps auto-sensing. Each port can independently identify (via
802.3u auto sensing) and accept either 100Mbps or 10Mbps Ethernet
signals, adapting to match the best speed of the connected device. There are
two internal traffic domains in Magnum Blade hubs, one for the 100Mbps
traffic and one for the 10Mbps traffic. The 100Mbps users share the
100Mbps domain’s bandwidth and the 10Mbps users share the 10Mbps
domain’s bandwidth.
The Magnum Blade Model DS12E has 12 RJ-45 ports, fixed at
100Mbps speed. There is no auto-negotiation and no uncertainty about the
operating speed accordingly.
Magnum Blade Hubs have an up-link switch at port # 1, located on
the top-front to either connect to a user station or node (= position) or
alternatively to be cascaded to another hub or switch (X position).
The Magnum Blade Hubs are in compliance with the IEEE 802.3u
standards. The Magnum Blade Hubs are equipped with LEDs per port,
providing for convenient monitoring of network operation. PWR LEDs
indicates the power up of the unit and COL LEDs indicates the common
collision at 10Mbps and 100MB. LINK / RX and 100LEDs on each port
indicate each port is operational or receiving data, and is at 100Mbpsspeed
when lit. The PWR LED indicates the power is applied to the unit and the
COL LEDs indicates common collision at 10Mbps and 100MB respectively.
