The NETGEAR® ProSAFE® S3300 Smart Switch is a high-performance, IEEE-compliant,
stackable switch with either 48
(models S3300-52X and S3300-52X-PoE+) or 24 (models
S3300-28X and S3300-28X-PoE+) twisted-pair ports on the front panel to support
10/100/1000
Mbps networks. In addition, the front panel provides two dedicated 10GBASE-T
ports and two dedicated SFP+ ports for connections to a server or network backbone. You can
configure the dedicated 10GBASE-T and SFP+ ports as stacking links to build a stack system
with other S3300 switches. To simplify installation, the smart switch is shipped ready for use out
of the box.
This hardware installation guide complements the installation guide that came with your smart
switch.

S3300 Smart Switch
Hardware Overview
This installation guide is for the following S3300 Smart Switch models:
•S3300-52X. Supports forty eight 10/100/1000 Mbps ports, two dedicated
100M/1G/10GBASE-T ports, and two dedicated 10G/1G SFP+ ports.
802.1at), two dedicated 100M/1G/10GBASE-T ports, and two dedicated 10G/1G
SFP+ ports.
•S3300-28X. Supports twenty four 10/100/1000 Mbps ports, two dedicated
100M/1G/10GBASE-T ports, and two dedicated 10G/1G SFP+ ports.
•S3300-28X-PoE+. Supports twenty four 10/100/1000 Mbps PoE+ capable ports
(IEEE
802.1at), two dedicated 100M/1G/10GBASE-T ports, and two dedicated 10G/1G
SFP+ ports.
You can configure the dedicated 10GBASE-T and SFP+ ports on the smart switch either as
Ethernet ports or as stacking links.
Using these 10G copper and fiber ports, you can also create high-speed connections to a
server or network backbone. For example, you can do the following:
•Connect switches to each other with high-speed links
•Link to high-speed servers
•Provide 10G/1G/100M copper and 10G/1G fiber connectivity
•Connect up to six switches in a stack to create a high-port-capacity solution with a single
point of administration
The smart switch can be freestanding, stacked with other switches, or rack-mounted in a
wiring closet or equipment room. It is IEEE compliant and offers low latency for high-speed
networking.
All ports can automatically negotiate to the highest speed, which makes the smart switch very
suitable for environments with a mix of Ethernet, Fast Ethernet, Gigabit Ethernet, or
10-Gigabit Ethernet devices. The 10/100 Mbps ports can operate in half-duplex or full-duplex
mode. The 10G/1G ports always operate in full-duplex mode.
The maximum segment length is 328 feet (100 meters) over Category 5 unshielded
twisted-pair (UTP) cable. For 10GBASE-T connections, NETGEAR recommends that you
use a Category
6a cable or a cable that is even higher rated.

The S3300 Smart Switch includes the following key hardware features:
•Forty eight (S3300-52X and S3300-52X-PoE+) or twenty four (S3300-28X and

Introduction Hardware Installation Guide8
S3300 Smart Switch
Stacking
A single switch can control and manage a stack. This switch is referred to as the stack
master, or simply, the master. Any other members in the stack are referred to as slaves. All
switches in a stack are stack members.
Slaves can download firmware from the master and the master can push firmware to the
slaves.
The master runs the fully operational software of a switch. In addition, the master runs the
master software of the distributed switching application that configures and manages all
slaves. Generally, the master operates the remote slave’s low-level drivers through the
distributed switching application part that is running in the context of the slave.
During stacking setup, the switches autoselect one switch as the master. All other switches
become slaves and are assigned unique stack IDs. One of the slaves is designated as the
backup master. The backup master functions as a slave but can become the master if the
original master fails. In the default configuration, the master and backup master are assigned
unit IDs of 1 and 2, respectively. You can use the web management interface to configure
different ID assignments. The master provides a single point of control and management as
well as a single interface through which to control and manage the stack.
Switch software is downloaded separately for each stack member. However, all stack
members must be running the same software version.
A stack unit can operate in one of the following modes:
•A standalone switch runs as a general switch. The standalone unit does not run the
stacking application until it is connected to a stack.
•A master manages the entire stack and is responsible for the entire stack configuration.
All protocols run in the context of the master, which updates and synchronizes the backup
master.
•A backup master runs as a slave until it must take over from the master. In addition, the
backup master continuously monitors the existence and operation of the master. If the
master fails, the backup master assumes the role of master through a switchover.
•A slave runs only a slave version of the distributed switching software, which allows the
applications running on the master to control and manage the resources of the slave.
A stack can contain a mix of up to six S3300 switches. All S3300 models support stacking.
