ONNECTING THE SWITCH SYSTEM
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 rack-mount
screws to mount the switch in the rack.
Connecting the Switch System
The EZ Switch 10/100/1000 provides 5/8 RJ-45 ports on this device.
Each of these ports supports connection to 10 Mbps Ethernet,
100 Mbps Fast Ethernet, or 1000 Mbps Gigabit Ethernet. In addition, they
are capable of operating at either half or full-duplex at 10 or 100 Mbps. At
1000 Mbps, only full-duplex operation is supported. 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 supported by the attached
device).
Making a Connection to an RJ-45 Port
Because all RJ-45 ports on these switches support automatic MDI/MDI-X
operation, you can use straight-through cables for all network connections
to PCs or servers, or to other switches or hubs. Note that auto-negotiation
must be enabled for automatic MDI/MDI-X pinout configuration.
1. Prepare the network devices you wish to network. Make sure you have
installed 1000BASE-T network interface cards for connecting to the
switch’s RJ-45 ports.
2. Prepare straight-through shielded or unshielded twisted-pair cables
with RJ-45 plugs at both ends. Use 100-ohm Category 3, 4 or 5 cable
for standard 10 Mbps Ethernet connections, 100-ohm Category 5
cable for 100 Mbps Fast Ethernet connections, or 100-ohm Category
5 or 5e cable for 1000 Mbps Gigabit Ethernet.
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 10 Mbps, 100 Mbps and 1000 Mbps

NSTALLING THE SWITCH
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 end nodes.
Caution: Do not plug a phone jack connector into any RJ-45 port.
This may damage the switch. Instead, 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 5e cable for all network
connections or testing existing Category 5 cable to be
sure that it complies with the IEEE 802.3ab standards.
(See “1000BASE-T Cable Requirements” on page 17.)
Restrictions on Cascade Length - The IEEE 802.3 standard
recommends restricting the number of hubs (i.e., repeaters)
cascaded via twisted-pair cable to four; 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 because switches break up the path for connected
devices into separate collision domains, you should not include
switch or connected cabling in your calculations for cascade
the
length involving other devices.

P
OWERING ON THE SWITCH
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 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 switch performs a self-diagnostic test upon power-on. (Note that
this test takes several seconds to complete.)
Note: The unit supports a “hot remove” feature which permits you to
connect or disconnect twisted-pair cables without powering off
the switch and without disrupting the operation of the devices
attached to the switch.

Verifying System Operation
Verify that all attached devices have a valid connection. The switch
monitors the link status for each port. If any device is properly
connected to the switch and transmitting a link signal, the port
8
LED indicator will light up for the corresponding port. If the port
LED indicator fails to light when you connect a device to the
switch, check the following items:
• Be sure all network cables and connectors are properly
attached to the connected device and the switch.
• 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.
• Be sure no twisted-pair cable exceeds 100 meters (328 feet).
Applications
This switch segments your network, significantly increasing both
bandwidth and throughput. Each port on the switch can be
attached to any IEEE 802.3ab-compliant Gigabit Ethernet device,
such as another switch, full-duplex repeater, or a server’s network
adapter. All switch ports operate at 1 Gbps, full duplex, providing
2 Gbps of bandwidth to the attached device.

PPLICATIONS
Bridging Functions – This switch provides fully transparent
bridging functions. It automatically learns node addresses that are
subsequently used to filter and forward all traffic based on the
destination address. When traffic passes between devices attached
to the same shared collision domain, those packets are filtered
from the switch. But when traffic must be passed between unique
segments (i.e., different ports on the switch), the high-speed
switching fabric forwards the packets at near zero latency.
Switching Functions – Store-and-forward switching is used to
forward traffic to other ports. This scheme ensures data integrity
and provides a clean data stream.
Sample Application – This switch is designed to operate as a
high-bandwidth backbone switch. It segments the core of the network,

ROUBLESHOOTING
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 fans on the
right side of the unit are unobstructed and running prior to shutdown. If
you still cannot isolate the problem, then the internal power supply may be
defective.
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.

ABLE TESTING FOR EXISTING CATEGOR Y
1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX connections
should also work for 1000BASE-T, providing that all four wire pairs are
connected. However, it is recommended that for all critical connections,
or any new cable installations, Category 5e (enhanced Category 5) cable
should be used. The Category 5e specification includes test parameters
that are only recommendations for Category 5. Therefore, the first step in
preparing existing Category 5 cabling for running 1000BASE-T is a simple
test of the cable installation to be sure that it complies with the IEEE
802.3ab standards.
Cable Testing for Existing Category 5 Cable
Installed Category 5 cabling must pass tests for Attenuation, Near-End
Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This cable testing
information is specified in the ANSI/TIA/EIA-TSB-67 standard.
Additionally, cables must also pass test parameters for Return Loss and
Equal-Level Far-End Crosstalk (ELFEXT). These tests are specified in the
ANSI/TIA/EIA-TSB-95 Bulletin, “The Additional Transmission
Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”
Note that when testing your cable installation, be sure to include all patch
cables between switches and end devices.

Adjusting Existing Category 5 Cabling
If your existing Category 5 installation does not meet one of the test
parameters for 1000BASE-T, there are basically three measures that can be
applied to try to correct the problem:
1. Replace any Category 5 patch cables with high-performance Category
5e cables.
2. Reduce the number of connectors used in the link.
3. Reconnect some of the connectors in the link.
