Introduction
48-Port 10/100 + 4-Port Gigabit Switch with WebView and Power over Ethernet
Chapter 1
Chapter 1:
Introduction
Thank you for choosing the 48-Port 10/100 + 4-Port
Gigabit Switch with WebView and Power over Ethernet.
This Switch will allow you to network better than ever.
The 48-Port 10/100 + 4-Port Gigabit Switch with WebView
delivers non-blocking, wire speed switching for your 10
and 100 megabit network clients, plus multiple options
for connecting to your network backbone. Forty-eight
10/100 ports wire up your workstations, while the four
integrated 10/100/1000 ports connect to other switches
and the backbone at Gigabit speeds. The miniGBIC ports
allow future expansion through alternate transmission
media like optical fiber.
All of the 10/100 ports on the Switch support pre-standard
and IEEE 802.3af standard (802.3af) Power over Ethernet
(PoE) capabilities. Each port can detect connected pre-
standard and 802.3af-compliant network devices, such
as IP phones or wireless access points, and automatically
supply the required DC power.
The Switch can provide DC power to a wide range of
connected devices, eliminating the need for an additional
power source and cutting down on the amount of cables
attached to each device. Once configured to supply
power, an automatic detection process is initialized by the
Switch that is authenticated by a PoE signature from the
connected device. Detection and authentication prevent
damage to non-PoE devices.
TheSwitchfeaturesWebViewmonitoringandconfiguration
via your web browser, making it easy to manage the 256
VLANs and up to 8 trunking groups. Or if you prefer, you
can use the integrated console port to configure the
Switch. The non-blocking, wire-speed switching forwards
packets as fast as your network can deliver them.
All ports have automatic MDI/MDI-X crossover detection.
Each port independently and automatically negotiates the
best speed and whether to run in half- or full-duplex mode.
Head-of-line blocking prevention keeps your high-speed
clients from bogging down in lower-speed traffic and fast
store-and-forward switching prevents damaged packets
from being passed on into the network.
Use the instructions in this User Guide to help you connect
the Switch, set it up, and configure it to bridge your
different networks. These instructions should be all you
need to get the most out of the 48-Port 10/100 + 4-Port
Gigabit Switch with WebView and Power over Ethernet.

Front Panel
The LEDs and ports are located on the front panel of the
Switch.
Front Panel
POWER (Green/Amber) Lights up green to
indicate that power is being supplied to the
Switch. Lights amber to indicate that the Switch’s
power-on-self-test (POST) is in progress. Blinks
amber to indicate that the POST has failed.
LINK/ACT (1-48) (Green/Amber) Lights up
green to indicate a functional 10/100Mbps
network link through the corresponding port
with an attached device that does not use Power
over Ethernet (PoE). Lights up amber to indicate a
functional 10/100Mbps network link through the
corresponding port with an attached PoE device.
Blinks green to indicate that the Switch is actively
sending or receiving data over that port.
LINK/ACT (G1-G4) (Green/Amber) Lights up
green to indicate a functional 10/100Mbps
network link through the corresponding port
with an attached device. Blinks green to indicate
that the Switch is actively sending or receiving
data over that port. Lights amber to indicate a
functional 1000Mbps network link. Blinks green
to indicate that the Switch is actively sending
or receiving data over that port. No amber light
indicated that the link is at 10/100Mbps or there
is no link.
ETHERNET 1-48 These RJ-45 ports support
network speeds of either 10Mbps or 100Mbps,
and can operate in half and full-duplex modes.
Auto-sensing technology enables each port to
automatically detect the speed of the device
connected to it (10Mbps or 100Mbps), and adjust
its speed and duplex accordingly.
The Switch’s 10/100 RJ-45 ports also support the
IEEE 802.3af Power-over-Ethernet (PoE) standard
that enables DC power to be supplied to attached
devicesusingwiresintheconnectingtwisted-pair
cable. Any 802.3af-compliant device attached to
a port can directly draw power from the Switch
over the twisted-pair cable without requiring its
own separate power source. This capability gives
networkadministratorscentralizedpowercontrol
for devices such as IP phones and wireless access
points, which translates into greater network
availability.
For each attached 802.3af-compliant device,
the Switch automatically senses the load and
dynamically supplies the required power. The
Switch delivers power to a device using the two
data wire pairs in the twisted-pair cable. Each
port can provide up to 15.4W of power at the
standard -48 VDC voltage.
To connect a device to a port, you will need to
use Category 5 (or better) network cable.
ETHERNET G1-G4 The Switch is equipped with
four Gigabit RJ-45 ports, two that are shared with
two miniGBIC ports. If a Gigabit miniGBIC port is
being used, the associated RJ-45 port (G3 and/or
G4) cannot be used.
All four ports support auto-negotiation, so the
optimum transmission mode (half or full duplex)
and data rate (10, 100, or 1000 Mbps) can be
selected automatically, if this feature is also
supported by the attached device. If a device
connected to one of these ports does not support
auto-negotiation, the communication mode of
that port can be configured manually.
Each port also supports IEEE 802.3-2002
auto-negotiation of flow control, so the Switch
can automatically prevent port buffers from
becoming saturated.
These ports support automatic MDI/MDI-X
operation, so you can use straight-through cables
for all network connections to PCs, servers, or
additional switches.

MiniGBIC (1-2) The Switch is equipped with
two miniGBIC ports that have shared Gigabit
Ethernet ports (G3 and G4) which provide for
the installation of one expansion module. These
ports provide links to high-speed network
segments or individual workstations at speeds of
up to 1000Mbps (Gigabit Ethernet).
To establish a Gigabit Ethernet connection using
a miniGBIC port, you will need to install a MGBT1,
MGBSX2, or MGBLH1 Gigabit expansion module
and use Category 5e cabling or fiber optic
cabling.
To establish a Fast Ethernet connection using a
miniGBIC port, you will need to install a MFEFX1
(100BASE-FX) or MFELX1 (100BASE-LX) 100SFP

Pre-Installation Considerations
Fast Ethernet Considerations
If you are using the Switch for Fast Ethernet (100Mbps)
applications, you must observe the following guidelines:
Full-Duplex Considerations
The Switch provides full-duplex support for its RJ-45
ports. Full-duplex operation allows data to be sent and
received simultaneously, doubling a port’s potential data
throughput. If you will be using the Switch in full-duplex
mode, the maximum cable length using Category 5 cable
is 328 feet (100 meters).
1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100Base-TX
connections should also work for 1000Base-T, providing
that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any
new cable installations, Category 5e (enhanced Category
5) or Category 6 cable should be used. The Category
5e specification includes test parameters that are only
recommendations for Category 5. Therefore, the first
step in preparing existing Category 5 cabling for running
1000Base-T is a simple test of the cable installation to be
sure that it complies with the IEEE 802.3ab standards.
Positioning the Switch
Before you choose a location for the Switch, observe the
following guidelines:
Make sure that the Switch is accessible and that the
cables can be connected easily.
Keep cabling away from sources of electrical noise,
power lines, and fluorescent lighting fixtures.
Position the Switch away from water and moisture
sources.
To ensure adequate air flow around the Switch, be
sure to provide a minimum clearance of two inches
(50mm).
Do not stack free-standing Switches more than four
units high.
Placement Options
There are two ways to physically install the Switch, either
setthe Switch on itsfourrubberfeetfor desktop placement
or mount the switch in a standard-sized, 19-inch high rack
for rack-mount placement.

Desktop Placement
Attach the rubber feet to the recessed areas on the
bottom of the Switch.
Place the Switch on a desktop near an AC power
source.
Keep enough ventilation space for the switch and
check the environmental restrictions mentioned in
“Appendix C: Specifications” as you are placing the
Switch.
Connect the Switch to network devices according to
the Hardware Installation instructions below.
Attaching the Switch’s Rubber Feet
Rack-Mount Placement
To rack-mount the Switch in any standard 19-inch rack,
follow the instructions described below.
Place the Switch on a hard flat surface with the front
panel faced towards your front side.
Attach a rack–mount bracket to one side of the Switch
with the supplied screws and secure the bracket
tightly.
Attaching the Brackets
Follow the same steps to attach the other bracket to
the opposite side.
After the brackets are attached to the Switch, use
suitable screws to securely attach the brackets to any
standard 19-inch rack.

Mounting in Rack
Connect the Switch to network devices according to
the Hardware Installation instructions below.
Hardware Installation
To connect network devices to the Switch, follow these
instructions:
Make sure all the devices you will connect to the Switch
are powered off.
Connect a Category 5 Ethernet network cable to one
of the numbered ports on the Switch.
Connect the other end to a PC or other network
device.
Repeat steps 2 and 3 to connect additional devices.
If pre-standard or 802.3af-compliant PoE devices are
connected to the Switch’s 10/100 ports, the Switch
automatically supplies the required power.
If you are using a miniGBIC port, then connect a
miniGBIC module to the miniGBIC port. For detailed
instructions, refer to the module’s documentation.
Connect the supplied power cord to the Switch’s
power port, and plug the other end into an electrical
outlet. When connecting power, always use a surge
protector.
Power on the devices connected to the Switch. Each
active port’s corresponding LED will light up on the
Switch.
Uplinking the Switch
To uplink the Switch, connect one end of a Cat 5 (or better)
Ethernet network cable into one of the 4 gigabit ports, and
then connect the other end of the cable into the peripheral
device’s uplink port. MDI/MDIX will automatically detect
the speed and cable type.
The hardware installation is complete. Proceed to“Chapter
4: Configuration using the Console Interface”, for directions
on how to set up the Switch.
