Note: If more than one hub with internal switching is used in the stack, switching
between stack segments will be managed by the unit highest in the stack, and
internal switching will be disabled for all other units.
These hubs provide a friendly design that simplifies installation and network
troubleshooting. The following figure shows the components of this hub:
Mounting the Hub
These hubs can be placed directly on your desktop, or mounted in a rack.
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: 100 to 240 VAC (± 10%) at 50 to 60 Hz (± 3Hz). The hub's
power supply automatically adjusts 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.
If you intend to mount the hub in a rack, make sure you have all the necessary
mounting screws, brackets, bolts and nuts, and the right tools.
Check if network cables and connectors needed for installation are available.
Stacking Hubs on a Flat Surface
These CheetaHubs can be stacked anywhere there is a enough flat space, such as
on a table or desktop.
1. Stick the self-adhesive rubber foot
pads (that come with this package)
on each of the 4 concave spaces
located on the bottom of the first hub.
2. Place the first hub on a firm flat
surface where you want to install the
stack.
3. Repeat step 1 for each hub before stacking them. The rubber foot pads cushion
the hub against shock/vibrations and provide space between each hub for
ventilation.
Mounting Hubs in a Rack
Please comply with the following
instructions to ensure that your hub is
securely mounted in the rack.
1. Use a standard EIA 19-inch rack.
2. Use the brackets and screws supplied
in the rack mounting kit.
3. Use a cross-head screwdriver to attach the brackets to the side of the hub.
4. Position the hub in the rack by lining up the holes in the brackets with the
appropriate holes on the rack, and then use the supplied screws to mount the
hub in the rack.
Connecting the Hub System
These hubs have 8 (or 16) dual-speed RJ-45 station ports, one of which also serves
as a dual-speed MDI daisy-chain port. Two stack backplane ports are also located
on the rear panel; using these ports you can stack up to six hubs.
Making a Connection via an RJ-45 Station Port
You can connect any RJ-45 (MDI-X) station port on the hub to any device that uses
a standard network interface such as a workstation or server, or to a network
interconnection device such as a bridge or router (depending on the port type
implemented).
1. Prepare the network devices you wish to network. Make sure you have installed
10BASE-T or 100BASE-TX network interface cards for connecting to the hub's
RJ-45 (MDI-X) station ports. You also need to prepare straight-through shielded
or unshielded twisted-pair cables with RJ-45 plugs at both ends. Use 100W
Category 3, 4 or 5 cable for standard 10 Mbps Ethernet connections, or 100W
Category 5 cable for 100 Mbps Fast Ethernet connections.
2. Connect one end of the cable to the RJ-45 port of the network interface card, and
the other end to any available (MDI-X) station port on the hub. The RJ-45 ports
support 10 Mbps and 100 Mbps Ethernet connections. When inserting an RJ-45
plug, be sure the tab on the plug clicks into position to ensure that it is properly
seated. Using a hub in a stand-alone configuration, you can network up to 8 (16)
end nodes.
I
Do not plug a phone jack connector into any RJ-45 port. This may damage the hub.
Use only twisted-pair cables with RJ-45 connectors that conform with FCC
standards.
Notes: 1. Make sure each twisted-pair cable does not exceed 100 meters (328 feet).
2. We advise using Category 5 cable for all network connections to avoid any
confusion or inconvenience in the future when you upgrade attached devices
to Fast Ethernet.
Making a Connection via an MDI Daisy-Chain Port
1. To make a direct connection to another compatible hub or switch, use an RJ-45
daisy-chain port (ports with an associated MDI-X/MDI switch). Set the daisy-
chain switch to MDI and then connect to any MDI-X station port on the other
device. Alternatively, you can connect from any RJ-45 MDI-X port on the switch
to an MDI daisy-chain port on the other device.
