Description of Hardware
This hub contains 8 RJ-45 Fast Ethernet ports (MDI-X) for connecting to a
workstation or other compatible devices, and 1 daisy-chain port (used instead of
Port 8) for linking to another compatible hub or switch with straight-through twisted-
pair cable. The following figure shows the components of this hub:
Mounting the Hubs
This hub can be placed directly on your desktop or any other level surface.
Before you start installing the hub, make sure you can provide the right operating
environment, including power requirements, sufficient physical space, and proximity
to other network devices that are to be connected. Verify the following installation
requirements:
Power requirements
EH3008D: 13 - 14 VDC, 0.8A max.
EH3008F: 100 to 240 VAC (± 10%) at 50 to 60 Hz (± 3Hz)
Note: Both the external power adapter (for the EH3008D) and the internal power
supply (for the EH3008F) automatically adjust to the input voltage level.
The hub should be located in a cool dry place, with at least 10 cm. (4 in.) of
space at the front and back for ventilation.
Place the hub out of direct sunlight, and away from heat sources or areas with a
high amount of electromagnetic interference.
