Quick Installation Guide  
Introduction  
The CheetaHub Power-3008P/16P provides 8 (16) RJ-45  
ports that automatically adjust to the speed of the  
attached device (for 10Mbps Ethernet or 100Mbps Fast  
Ethernet connections). These dual-speed hubs contain  
two internal repeater buses – one for 10Mbps traffic and  
another for 100Mbps traffic. Traffic passing between  
attached devices that operate at the same speed is confined  
within the appropriate repeater bus. But when traffic must pass  
between 10 and 100Mbps devices, when the destination address is not found in  
the address table, or broadcast traffic is sent, data is forwarded to the other  
repeater bus via an internal 10/100Mbps switch.  
These hubs provide an ideal bridge between 10 and 100Mbps Ethernet networks.  
Moreover, the smart design built into the display panel provides a friendly  
interface that simplifies installation and network troubleshooting.  
Installing the Hub  
Before installing the hub, please verify that you have all the items listed under  
“Package Contents.” If any of the items are missing or damaged, contact your  
local Accton distributor. Also be sure you have all the necessary tools and  
cabling before installing the hub. Note that this hub can be installed on any  
suitably large flat surface or in a standard EIA 19-inch rack.  
Package Contents  
The CheetaHub Power-3008P/16P includes:  
• CheetaHub Power-3008P (Model No. EH3008P)  
Fast Ethernet dual-speed hub with 8 10/100Mbps ports, and internal switch  
or CheetaHub Power-3016P (Model No. EH3016P)  
Fast Ethernet dual-speed hub with 16 10/100Mbps ports, and internal switch  
• Four rubber foot pads  
• Rack mount bracket kit  
• Quick Installation Guide  
• Owner registration card  
• AC power cord  
Description of Hardware  
These hubs provide 8 (16) dual-speed ports (10/100 Mbps). Each port  
automatically senses the speed of the attached device, and channels data to the  
appropriate repeater bus. The learning function of the hub stores the node  
address and corresponding segment number (i.e., bus 1 or 2) of each incoming  
packet in a routing table. If the source and destination node operate at different  
speeds, this information is subsequently used to pass traffic to the segment  
1
1
 
CheetaHub Power-3008P/3016P  
containing the destination node via a 2-port switch that connects the two repeater  
buses. By confining traffic to its respective collision domain, and only forwarding  
traffic to the other segment when required, the overall load on the network is  
significantly reduced.  
These hubs provide a friendly design that simplifies installation and network  
troubleshooting. The following figure shows the components of the EH3016P:  
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 access to the ports and 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 any place where there is 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
 
Quick Installation Guide  
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 (16) dual-speed RJ-45 station ports, one of which also  
serves as a dual-speed MDI daisy-chain port.  
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 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.  
2. You also need to prepare straight-through shielded or unshielded twisted-pair  
cables with RJ-45 plugs at both ends. Use 100Category 3, 4 or 5 cable for  
standard 10Mbps Ethernet connections, or 100Category 5 cable for  
100Mbps Fast Ethernet connections.  
3
3
 
CheetaHub Power-3008P/3016P  
3. 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 10Mbps and 100Mbps 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.  
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  
To make a direct connection to another compatible hub or switch:  
1. Prepare straight-through shielded or unshielded twisted-pair cables with RJ-45  
plugs at both ends. Use 100Category 3, 4 or 5 cable for standard 10Mbps  
Ethernet connections, or 100Category 5 cable for 100Mbps Fast Ethernet  
connections.  
2. Plug one end of the network cable into Port 16MDI on the hub, and the other  
end to any MDI-X station port on the other device. When inserting an RJ-45  
plug, be sure the tab on the plug clicks into position to ensure that it is  
properly seated.  
Notes: 1. Make sure each twisted-pair cable does not exceed 100 meters (328  
feet).  
2. To connect to another hub or switch, you may also attach any RJ-45  
MDI-X port on the hub to an MDI daisy-chain port on the other device. Or  
attach crossover cabling to (MDI-X) station ports at both ends.  
Restrictions on Cascade Length - When cascading to another repeater, note  
that the attached repeaters will function as a single logical repeater, with all ports  
attached to the same collision domain.  
• 10 Mbps Cascade - Based on the IEEE 802.3 recommendation, you may  
cascade up to four 10Mbps hubs.  
• 100 Mbps Cascade - When cascading to a Fast Ethernet hub, limit the daisy-  
chain to two hubs. Another limitation for cascading Fast Ethernet concerns  
connection length. All end-node devices (e.g., workstations or servers) must  
be within 100 meters (328 feet) of the connected hub; and the overall length  
between any two nodes should not exceed 205 meters (672 feet). The easiest  
way to cascade two Fast Ethernet hubs is to connect the MDI daisy-chain port  
on the front panel to an MDI-X port on the other hub. For example, if both  
node A and B are linked to separate repeaters in a two hub system, each using  
100 meters of cable to connect to their respective hub, then the inter-hub  
4
 
Quick Installation Guide  
cabling will be limited to 5 meters (16 feet). The only way to extend the inter-  
hub cabling, would therefore be to reduce the length of the cabling used to  
attach the end nodes to the hubs.  
Ethernet Switch - There are no formal restrictions on cascade length if a  
device is connected to a switch, which effectively breaks up the collision  
domain. When a collision domain is broken up by a device like a switch,  
cascade length is limited only by the time-out requirements of the particular  
applications running over the network.  
Powering On the Hub  
1. Plug the power cord into the power socket at the rear of the hub, and the  
other end into a power outlet.  
2. Check the LED marked Power on the front panel to see if it is on. The unit will  
automatically select the setting that matches the connected input voltage.  
Therefore, no additional adjustments are necessary when connecting it to any  
input voltage within the range marked on the rear panel.  
3. The hub performs a self-diagnostic test upon power-on.  
Note: The unit supports a "hot remove" feature which permits you to connect/  
disconnect cables without powering off the hub and without disrupting the  
operation of the devices attached to the hub.

Verifying System Operation  
Verify that all attached devices have a valid connection. The hub monitors the  
link status for each port. If any device is properly connected to the hub and  
transmitting a link beat signal, the Link indicator will light up for the  
corresponding port. If the Link indicator fails to light, see Troubleshooting on  
page 8.  
Applications  
These dual-speed CheetaHubs allow great flexibility in configuring your network.  
You can use them to mix and match legacy Ethernet and Fast Ethernet network  
resources on your local network. Moreover, you can easily extend your LAN by  
making a high-speed connection to a collapsed backbone device (e.g., a switch  
or a router).  
Stand-Alone Network - These CheetaHubs have an internal switching function  
that can be used in a simple stand-alone configuration as illustrated on the next  
page. Regardless of whether you are making 10 or 100 Mbps connections with  
twisted-pair cable, limit the distance for each cable to 100 meters (328 feet).  
Cascading Hubs with the Daisy-Chain Port - You can easily connect to  
another hub or switch via the RJ-45 MDI daisy-chain port on the front panel. The  
figure on the next page shows a sample configuration. When connecting to  
10Mbps Ethernet, the maximum number of hubs that can be cascaded is four  
(with up to 100 meters or 328 feet of cable allowed between each hub). However,  
when connecting to another Fast Ethernet hub, the number of hubs that can be  
cascaded is limited to two, and the total network span allowed is only 205 meters  
(672 feet).

Diagnosing Hub Indicators  
The hub can be easily monitored through panel indicators to assist the network  
manager in identifying problems. This section describes common problems you  
may encounter and possible solutions.  
Symptom: Power indicator does not light up (green) after power on.  
Cause:  
Defective power outlet, power cord, or internal power supply.  
Solution: Check the power outlet by plugging in another device that is functioning  
properly. Check the power cord with another device. If these measures  
fail to resolve the problem, have the unit's power supply replaced by a  
qualified Accton distributor.  
Symptom: Link indicator does not light up after making a connection.  
Cause:  
Network interface (e.g., a network adapter card on the attached device),  
network cable, or hub port is defective.  
Solution: Verify that the hub and attached device are powered on. Be sure the  
cable is plugged into both the hub and corresponding device. Verify that  
the proper cable type is used and its length does not exceed specified  
limits. Check the adapter on the attached device and cable connections  
for possible defects. Replace the defective adapter or cable if necessary.

Quick Installation Guide  
Power and Cooling Problems  
If the Power indicator does not turn on when the power cord is plugged in, you  
may have a problem with the power outlet, power cord, or internal power supply  
as explained in the previous section. However, if the unit powers off after  
running for a while, check for loose power connections, power losses or surges  
at the power outlet, and verify that the fan on back of the unit is unobstructed and  
running prior to shutdown. If you still cannot isolate the problem, then the  
internal power supply may be defective. In this case, contact your Accton  
distributor for assistance.  
Cabling and Adapters  
If the Link indicator fails to light when you connect a device to the hub, check the  
following items:  
Be sure the twisted-pair cable is properly attached to the connected device  
and the hub. Verify that the media connector snaps into place when attached.  
See if your cable is functioning properly by using it for another port and  
attached device that displays valid indications when connected to the network.  
Check the length of each twisted-pair cable to be sure it does not exceed 100  
meters (328 feet). If you have cascaded two Fast Ethernet hubs together, be  
sure the interhub cabling is no longer than 5 meters (16 feet).  
Verify that the workstation's adapter card is functioning properly by trying it in  
another computer that has been successfully connected to the network.  
Installation  
Verify that all system components have been properly installed. If one or more  
components appear to be malfunctioning (e.g., the power cord or network  
cabling), test them in an alternate environment where you are sure that all the  
other components are functioning properly.
