Installation

Choosing a Location

The 10/100 Managed Hub location should be less than 100 meters from servers, workstations, or switches. The 10/100 Managed Hub can be desk mounted or rack mounted.

CAUTION: Category 5 UTP/STP cables are environmentally sensitive. Make sure that the cable route is not too close to electrical noise sources such as power lines or fluorescent lights.

Stacking

The 10/100 Managed Hubs are stackable in standard 19” racks. Up to six hubs can be stacked with cascade cables. One master and up to five slaves can make up a stack. The master can be positioned anywhere in the stack, so you can add to a stack without re-positioning the hubs.

Rack Mounting

Rack mounting brackets are included to mount hubs in a standard EIA 19-inch racks.

Align the mounting brackets on the sides of the unit with the slit over the holes. Secure the screws tightly to fix the brackets to the device. Then, place the device into the 19” rack and affix it properly. Please ensure that the ventilation holes on the unit are not blocked.

Using Cascade Cables

You can stack the 10/100 Managed Hubs using cascade cables. The master hub can be placed anywhere in the stack. By cascading the hub stack, each hub is automatically identified and assigned an ID number according to its position in the stack.
