The standard limited warranty can be upgraded to a Limited Lifetime* warranty by registering
new products within 30 days of purchase from SMC or its Authorized Reseller. Registration
can be accomplished via the enclosed product registration card or online via the SMC Web
site. Failure to register will not affect the standard limited warranty. The Limited Lifetime
warranty covers a product during the Life of that Product, which is defined as the period of
time during which the product is an “Active” SMC product. A product is considered to be
“Active” while it is listed on the current SMC price list. As new technologies emerge, older
technologies become obsolete and SMC will, at its discretion, replace an older product in its
product line with one that incorporates these newer technologies. At that point, the obsolete
product is discontinued and is no longer an “Active” SMC product. A list of discontinued
products with their respective dates of discontinuance can be found at:

before installing the Switch:
WARNING: Installation and removal of the unit must be carried out by
qualified personnel only.
• This guide is intended for use by network administrators who are
responsible for setting up and installing network equipment;
consequently it assumes a basic working knowledge of LANs (Local Area
Networks).
• The unit must be connected to an earthed (grounded) outlet to comply
with international safety standards.
• Do not connect the unit to an A.C. outlet (power supply) without an

I NTRODUCTION
The EZ Switch™ 10/100/1000, SMCGS16 and SMCGS24, are
high-performance Gigabit Ethernet switches designed for delivering
Gigabit connectivity to the desktop. They provide 16/24 full-duplex
1000BASE-T ports that significantly improve network performance and
boost throughput for high-bandwidth applications. With 32/48 Gigabits
of throughput bandwidth, these switches provide the quickest solution to
meeting the growing demands on your network.
Features and Benefits
• Auto-negotiation supported on all ports
• Automatic MDI/MDI-X operation
• IEEE IEEE 802.3-2002 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
The EZ Switch 10/100/1000 features 16/24 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
