NTRODUCTION
The EZ Switch 10/100/1000, SMC8505T and SMC8508T, are
high-performance Gigabit Ethernet switches designed for delivering
Gigabit connectivity to the desktop. They provide 5/8 full-duplex
1000BASE-T ports that significantly improve network performance
and boost throughput for high-bandwidth applications. With 10/16
Gigabits of aggregate bandwidth, these switches provide the quickest
solution to meeting the growing demands on your network’s limited
resources.
Features and Benefits
• Auto-negotiation supported on all ports.
• Automatic MDI/MDI-X operation.
• IEEE 802.3ab, 802.3u, and 802.3 compliance ensures compatibility
with standards-based hubs, switches and cards from any vendor.
• Store-and-forward switching ensures error-free transmission.
• Half- and full-duplex flow control prevents packets from being
dropped under heavy loading.
• Plug-and-play—nothing to configure.
• “At-a-glance” LEDs for port and system status monitoring.
• Desktop or rack installation.

Front Panel RJ-45 Ports
These EZ Switch 10/100 models feature 5/8 1000BASE-T ports with RJ-45
connectors located on the front panel of the switch. Because all ports
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.
Front Panel LEDs
The front panel of the switch provides status LEDs for “at-a-glance”
system monitoring. The following table details the functions of the
various indicators.
Port and System Status LEDs
LED Condition Status
Power On The switch is receiving power.
Off The switch is not receiving power.
Ports
Link/Act On The port has established a valid network
connection.
Off The port has not established a network
connection.
Flashing Traffic is passing through the port.
1000M On Indicates the port is operating at 1000 Mbps.
Off Indicates the port is not operating at
1000 Mbps.
10/100M On Indicates the port is operating at 100 Mbps.
Off Indicates the port is operating at 10 Mbps.

Before installing the switch, verify that you have all the items listed under
“Package Contents.” Note that the switch can be installed on any suitably
large flat surface or in a standard EIA 19-inch rack.
Package Contents
The EZ Switch 10/100/1000 includes:
Selecting a Site
Be sure to follow the site selection guidelines below when choosing a
location:
• Select a suitable location for the switch:
• It should be accessible for installing, cabling and maintaining the
switch.
• The temperature and humidity should be within the ranges listed
in the specifications.
• The status LEDs should be clearly visible.
• EZ Switch 10/100/1000 (SMC8505T or SMC8508T).
• Four rubber foot pads.
• Rack-mount bracket kit.
• Appropriate DC power adapter.

• There should be adequate space (approximately two inches) on
all sides for proper air flow.
• Make sure twisted-pair cable is always routed away from power lines,
fluorescent lighting fixtures and other sources of electrical
interference such as radios, transmitters, etc.
• Make sure that a properly grounded power outlet is within 2.44
meters (8 feet) of the switch and is powered from an independent
circuit breaker. As with any equipment, using a filter or surge
suppressor is recommended.
Instructions
1. Positioning the Switch: For desktop or shelf mounting, attach
the four adhesive foot pads to the bottom of the switch. For rack
mounting, install into a standard EIA 19-inch rack using the included
brackets.
2. Applying Power: Plug one end of the power adapter into the socket
on the switch’s rear panel, and the other end into an appropriate
electrical outlet. Check the Power LED to be sure power is on.
Note: It is not necessary to power off the switch before connecting or
disconnecting any UTP cables, as these actions will not disrupt
the operation of other devices attached to the switch.
3. Connecting PCs: Connect each PC to an RJ-45 port on the switch
using Category 5, 5e, or 6 shielded or unshielded twisted-pair (UTP
or STP) cable, maximum length 100 meters (328 ft). The EZ Switch
10/100/1000 will support up to 5/8 PCs. All ports on the switch
support automatic MDI/MDI-X operation, so you can use
straight-through cables for all network connections to PCs or servers,
or to other switches or hubs.
Note: If an attached device does not support auto-negotiation, the
data rate will be sensed automatically and the communication
mode will default to half duplex.

4. Cascading Switches and Other Network Devices: All the ports on
the switch support automatic MDI/MDI-X configuration for cable
connections. This allows you to use straight-through cable to connect
to other switches or hubs from any port on the switch. No crossover
cables or other device settings are needed. See the “Cable
Specifications” on page 11 of this guide for further information.
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.
