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.

HARDWARE INSTALLATION

Installation Procedure

1. Connect power wires to a 12VDC source, generally available inside the

Compact PCI box.

2. Insert the power plug to the power jack at the bottom inside position.

This applies power to the unit. (It is low voltage, 12VDC, safe to handle

when power is applied)

3. Carefully slide the DS12 hub into the Compact PCI I/0 slot and screw it

tightly through upper and lower screws (provided).

4. Connect a device to a RJ-45 hub port using twisted pair cabling. For

unshielded twisted pair, note that the distance between the hub and the

device cannot exceed 100 m, and that the longest UTP cable path

through a 100Mb collision domain (max. of two Class II cascaded hubs)

should not exceed 205 meters.

5. The LINK indicator will indicate if the connection is properly made, and if

there is power on the device on the other end so that the segment is

ready to operate.

6. Connect each applicable device in your network using the same process.

7. Use the up-link switch on Port # 1 to make a cascaded (X-position)

connection.

Note: To reliably operate your network at 100Mb/s, you must use Category

5 wiring. Category 3 or Category 4 wire may sometimes seem to work, but it

will normally cause data loss and unreliable operation.

Stand-alone Configuration

In a simple stand-alone configuration, the up-link switch is in the “=“ or

upward position, and port # 1 (on the DS12 and DS12E) is used to connect

to a user or other node.

Multi-level Configurations, Cascading

If you want to connect more than 12 ports together, use the up-link port to

connect to another hub or switch. This is called “cascading”. Simply

connect the up-link port (port # 1) to any port on another hub or switch,

with the up-link set to the crossover (X) position. Note that cascaded

configurations should be compliant with Fast Ethernet collision domain

specifications.

TROUBLESHOOTING

This section contains information to help solve problems. If

either the Magnum Blade DS12 or DS12E cPCI hub is not functioning

properly, check that the hub was set up according to the instructions in

this manual.

If the DS12 or DS12E cPCI hub does not connect to the network,

•Check the Link / Activity LED lights on the ports. The Link LED on

each port in use should be ON, which indicates that the physical

wiring connection is made on both ends of the wire and that power

is ON for the devices at both ends.

If the Link / Activity LED light is not ON, check all connections at the

adapter or node, and at the hub.

•Try another port on the hub.

•Turn off the power of the hub, after a while re-power the hub.

•Make sure that the cable is installed properly.

The RJ-45 cable must be securely attached. If the problem persists, try

a different cable.

Other Important Tips

•Make sure the network adapter cards installed in the workstations

and cable connections are in good working condition. Also, make

sure adapter drivers are loaded.

•If you are using the up-link port, confirm that the up-link port is in

the correct position:

This up-link switch is “front” for the up-link setting; “back” for

regular (node) setting. The up-link switch enables cascading when

the switch is set to the crossover (X, or front) position. Alternately,

when the switch is set to the normal straight through (=, or back)

position, the port operates as a normal node-connection port.
