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.
