Chapter 1. Introduction of the Product
This chapter describes the features of the RGS-1024 24-port
Gigabit Ethernet Switch.
1.1 Overview of the Product
The RGS-1024 24-port Gigabit Ethernet Switch provides you with
a high-performance, low-cost, easy-to-use, seamless and
standard upgrade to boost your old network to 1000Mbps.
Increase the speed of your network server and backbone
connections make Gigabit a reality. Power users in the home,
office, workgroup, or creative production environment can now
move large, bandwidth-intensive files faster. Transfer graphics,
CGI, CAD, or multimedia files and other applications that have to
move large files across the network almost instantly.
The ROSEWILL RGS-1024 features a non-blocking switching
architecture that forwards and filters packets at full wire-speed for
maximum throughput, MAC address auto- learning and
auto-aging, IEEE802.3x flow control for full-duplex mode and
backpressure for half-duplex mode. It is compatible with all 10,100
and 1000Mbps Ethernet devices because it is standard-based. It
protects your existing network investments while providing you
with a straightforward migration path to faster Gigabit speeds.
The ROSEWILL RGS-1024 is plug-and-play and no configuration
is required. Auto MDI/MDI-X cable detection on all ports eliminate
the need for crossover cable or Uplink port. Each port can be
used as general ports or Uplink ports, and any port can be simply
plugged into a server, a hub, a router or a switch, using the
straight cable or crossover cable. Diagnostic LEDs which display

link status and activity, allowing you to quickly detect and correct
problems on the network.

1.3 IEEE 802.1p QoS
The RGS-1024 24-port Gigabit Ethernet Switch automatically
provides 802.1p priority queuing Quality of Service, which is an
implementation of the IEEE 802.1p standard. With 802.1p QoS
function, you can reserve bandwidth for important functions that
require a large bandwidth or have a high priority, such as VoIP
(Voice-over Internet Protocol), web browsing applications or video
conferencing.
The Switch has separate hardware queues on every physical port
which packets from various applications are mapped to and

24-Port Gigabit Ethernet Switch RGS-1024 User Manual
-8-
assigned a priority to. The illustration below shows how 802.1p
priority queuing is implemented on the Switch.
Mapping QoS on the Switch
The Switch has four priority queues labeled 0, 1, 2 and 3. The
untagged packets and the eight other IEEE 802.1p priority levels
defined by the standard are mapped to the four class queues
used on the Switch. Among these four priority queues on the
Switch, Class 3 has the highest priority, while Class 0 has the
lowest priority and Class 2 has higher priority compared with
Class 1. The Untagged packets and eight priority tags, specified in
IEEE 802.1p are mapped to the switch’s priority tags as follows:
zThe Untagged packets, priority 1 and 2 are assigned to the
switch’s Class 0 queue.
zPriority 0 and 3 are assigned to the switch’s Class 1 queue.
zPriority 4 and 5 are assigned to the switch’s Class 2 queue.
zPriority 6 and 7 are assigned to the switch’s Class 3 queue.
The Switch uses WRR (Weighted Robin Round) for scheduling.
WRR queue-scheduling algorithm schedules all the queues in
turn and every queue can be assured of a certain service time.
The default value of QoS mode on this Switch is “weight 1:2:4:8”
from Class 0 to Class 3 queue in turn.

Chapter 2. Installation
2.1 Mounting the Switch on a Desk
Before place the Switch on a desk, attach four rubber footpads to
the flutes on the Switch bottom, then lay the Switch on the
desktop, where can be have as much as 5kg placed on top.
Note:
1. The electrical outlet shall be installed near the device and
shall be easily accessible.
2. Make sure there is free space for radiating heat and air.
3. Make sure not to place anything too heavy on top of the switch.
2.2 Mounting the Switch in a Rack
The dimension of RGS-1024 is designed according to the
standard 19 rack-mountable steel case of Electronic Industries
Association.
Turn off all the equipment connected to the Switch before
mounting it in the rack, then rivet the two "L" brackets onto each
side of the Switch, fasten it with screws in the rack.
Figure 2-1 Rivet the “L” brackets onto the Switch

2.3 Power On
RGS-1024 24-port Gigabit Ethernet Switch is powered by AC
power supply. Powering on the Switch, it will automatically
initialize and its LED indicators should respond as follows:
1）All of the Link/Act and 1000Mbps LED indicators will flash
momentarily for one second, which represents a resetting of
the system.
2）The Power indicator will light up.
If the LED indicators don't respond as described above, please
check the power supply and connection.

¾POWER LED: This indicator will light solid red when the
Switch powers up. If the LED is not lit, please check the power
supply and connection.
¾Link/Act LED: This indicator will light solid green when the
corresponding port is connected to another device and will
flash green when data is being transmitted or received on the
working connection.
¾1000Mbps LED: This indicator will light solid green when the
corresponding port is connected to a 1000Mbps device.
