Introduction
These CheetahSwitches are ideal for moving workgroups
from the conventional 10Mbps shared Ethernet collision
domain to multiple dedicated Ethernet segments. These
switches deliver dedicated 10/100 Mbps links to each
attached AN segment (independent collision domain) or
attached PCs all with conventional cabling and adapters.
They completely eliminate the bottlenecks of shared
10Mbps Ethernet networks by providing a wide bandwidth of up to 3.2 Gbps. This
makes them ideal for increasing the throughput of interconnected Ethernet hubs
or server farms. On top of all that, they use auto-negotiation to select the optimal
transmission speed and communication mode for each connection. They use
store-and-forward switching to maintain maximum data integrity, even under
heavy loading.
Installing the Switch
Before installing the switch, 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 switch. Note that this switch can be installed on any
suitably large flat surface or in a standard EIA 19-inch rack.

Description of Hardware
These switches contain 8/16 10BASE-T / 100BASE-TX dual-speed ports. They
use auto-negotiation to set the transmission speed (10/100 Mbps) and mode
(half/full duplex). If the attached device does not support auto-negotiation, the
speed will still be correctly set by the switch using auto-sensing. However, full
duplex can only be supported if the attached device also uses auto-negotiation.

The following figure shows the components of these switches:
Mounting the Hub
This switch can be placed directly on your desktop, or mounted in a rack
(ES3016A).
Before you start installing the switch, 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: 110 to 230 VAC (± 10%) at 47 to 63 Hz (± 3Hz). The
switch's power supply automatically adjusts to the input voltage level.
The switch 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 switch out of direct sunlight, and away from heat sources or areas
with a high amount of electromagnetic interference.
If you intend to mount the switch in a rack (ES3016A), 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 Switches on a Flat Surface
The CheetahSwitch can be stacked
anywhere 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 switch.
2. Place the first switch on a firm flat surface where you want to install the stack.
3. Repeat step 1 for each switch before stacking them. The rubber foot pads
cushion the switch against shock/vibrations and provide space between each
switch for ventilation.

Mounting Switches in a Rack (ES3016A)
Please comply with the following
instructions to ensure that your switch
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 switch.
4. Position the switch 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 switch in the rack.
Connecting the Switch System
These CheetahSwitches have 8/16 RJ-45 ports that support connection to
10Mbps Ethernet or 100Mbps Fast Ethernet, and half or full-duplex operation.
The transmission speed for each port is automatically set by the switch to match
the highest speed supported by the connected device. The transmission mode
can be set for each port using auto-negotiation (if also used by the attached
device). However, full duplex can only be supported if the attached device also
uses auto-negotiation. Also note that this CheetahSwitch uses store-and-forward
switching to maintain maximum data integrity under any type of loading.
Making a Connection to an RJ-45 Port
You can use straight-through twisted-pair cable to connect any RJ-45 (MDI-X)
port on the switch 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 switch's RJ-45 (MDI-X) station ports.
2. Prepare straight-through shielded or unshielded twisted-pair cables with
RJ-45 plugs at both ends. Use 100Ω Category 3, 4 or 5 cable for standard
10Mbps Ethernet connections, or 100Ω Category 5 cable for 100Mbps Fast
Ethernet connections.
3. Connect one end of the cable to the RJ-45 port of the network interface card,
and the other end to any available RJ-45 port on the switch. All 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 the switch in a stand-alone configuration, you can
network up to 8/16 end nodes.

IDo not plug a phone jack connector into any RJ-45 port. This may damage the
switch. Instead, use only twisted-pair ca les with RJ-45 connectors that conform
with FCC standards.
Notes: 1. When using Port 8MDI-X on the ES3008A, do not use Port 8MDI.
2. Make sure each twisted-pair ca le does not exceed 100 meters (328 feet).
3. We advise using Category 5 ca le 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 M I aisy-Chain Port
To connect to another compatible switch or hub, take these steps:
1. Use the RJ-45 daisy-chain port (i.e., Port 8MDI on the ES3008A, Port 16MDI
on the ES3016A). When using the ES3016A, set the daisy-chain switch to
MDI and 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.
2. Prepare straight-through shielded or unshielded twisted-pair cables with
RJ-45 plugs at both ends. Use 100Ω Category 3, 4 or 5 cable for standard
10Mbps Ethernet connections, or 100Ω Category 5 cable for 100Mbps Fast
Ethernet connections.
3. Connect one end of the cable to Port 8MDI on the switch, 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. When using Port 8MDI on the ES3008A, do not use Port 8MDI-X.
2. Make sure each twisted-pair ca le does not exceed 100 meters (328 feet).
3. To connect to another switch or hu , you may also attach to (MDI-X)
station ports at oth ends if you use crossover ca ling. (Refer to Port
and Ca le Assignments on page 9 for a description of crossover ca le.)
Restrictions on Cascade Length - The IEEE 802.3 standard recommends
restricting the num er of hu s (i.e., repeaters) cascaded via twisted-pair ca le to 4;
while IEEE 802.3u provides even stricter recommendations for Fast Ethernet.
Therefore, when cascading devices other than this switch, please refer to the
accompanying documentation for cascade restrictions. However, note that ecause
switches reak up the path for connected devices into separate collision domains,
you should not include the switch or connected ca ling in your calculations for
cascade length involving other devices.
Powering On the Switch
1. Plug the power cord into the power socket at the rear of the switch, and the
other end into a power outlet.
2. Check the ED 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.
