NETGEAR JGS516 User Manual
Start Here
The NETGEAR JGS516 16-port Gigabit Ethernet Switch and JGS524 24-port Gigabit
Ethernet Switch provide you with a low-cost, high performance network solution, designed
to support power workgroups operating at speeds from 10 megabits per second (Mbps) to
1000 Mbps.
Gigabit Ethernet switches provide 10 times the bandwidth that Fast Ethernet switches do,
boosting the speed at which files, voice, video, imaging, or other applications move across
your network.
Each of the JGS500 series switches offer both non-blocking performance to maximize your
network throughput and plug-and-play simplicity to use it. Every port negotiates to the
highest supported speed, enabling you to mix legacy Ethernet gear with newer products on
one network. This simplifies your upgrade to a complete gigabit network and keeps the
project within your budget.
LEDs
Network Port
All ports on the switch are 10/100/1000 Mbps capable ports that auto negotiate for speed,
and duplex. Additionally, all ports have Auto Uplink™to make the right connection.
Auto Uplink
™
The Auto Uplink technology that Netgear has included in this product will automatically
sense whether the straight-through cable plugged into any port should have a “normal”
connection, e.g., connecting to a PC; or an “uplink” connection, e.g. connecting to a
router, switch, or hub. That port will then configure itself to the correct configuration.
This feature also eliminates the need to worry about crossover cables, as Auto Uplink will
accommodate either type of cable to make the right connection.
Note: Auto Uplink will compensate for setting uplink connections, and crossover or
straight-through cables. Using Auto Uplink to create multiple paths between any two
network devices will disable your network.
Applications
Desktop Switching
Model JGS516/JGS524 Gigabit Ethernet Switch is used as a desktop switch to build a
small network that enables users to have 1000 Mbps access to file servers. Due to the the
full-duplex nature of Gigabit Ethernet, each connection will actually move 2000 Mbps of
data (1000 Mbps in each direction).

Install the Switch
To install your switch on a flat surface, you do not need any special tools. Be sure the
switch is positioned with at least 2 inches of space on all sides for ventilation.
To install the switch in a rack, first attach the mounting brackets to the side of the switch.
Insert the screws provided in the rack mount kit through each bracket mounting hole in
the switch. Tighten the screws with a #1 Phillips screwdriver to secure each bracket. Align
the mounting holes in the brackets with the holes in the rack and insert two pan-head
screws with nylon washers through each bracket and into the rack. Tighten the screws
with a #2 Phillips screwdriver to secure the switch in the rack.
Connect the Devices
To connect devices to the switch:
1. Connect the devices to the 10/100/1000 Mbps ports on the switch, using Category 5
UTP cable and RJ-45 plug.
Note: Ethernet specifications limit the cable between your PC or server and the
switch to 328 feet (100 meters) in length.
2. Connect one end of the DC power adapter cable to the power outlet on the rear
panel of the switch and other end of the power adapter cable to wall outlet.
