UNPACKING AND INSTALLATION
This chapter provides unpacking and installation information for the Switch.
Unpacking
Open the shipping cartons of the Switch and carefully unpacks its contents. The carton should contain the following items:
±
One Web Smart 48+2G-Port 10/100/1000Mbps/SFP Switch
±
One AC power cord, suitable for your area’s electrical power connections
±
Four rubber feet to be used for shock cushioning
±
Screws and two mounting brackets
±
CD-Rom with Web Management Utility and User’s Guide
If any item is found missing or damaged, please contact your local reseller for replacement.
Installation
The site where you install the hub stack may greatly affect its performance. When installing, consider the following pointers:
Install the Switch in a fairly cool and dry place. See
Technical Specifications
for the acceptable temperature and humidity operating
ranges.
Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to
sunlight.
Leave at least 10cm (about 4 inches) of space at the front and rear of the hub for ventilation.
Install the Switch on a sturdy, level surface that can support its weight, or in an EIA standard-size equipment rack. For information on
rack installation, see the next section, titled Rack Mounting
.
When installing the Switch on a level surface, attach the rubber feet to the bottom of each device. The rubber feet cushion the hub and
protect the hub case from scratching.
Rack Mounting
The Switch can be mounted in an EIA standard-size, 19-inch rack, which can be placed in a wiring closet with other equipment.
Attach the mounting brackets at the Switch’s front panel (one on each side), and secure them with the provided screws.
Figure 1. Combine the Switch with the provided screws
Then, use screws provided with the equipment rack to mount each Switch in the rack.
Figure 2. Mount the Switch in the rack
Connecting Network Cable
The Switch supports 10Mbps Ethernet or 100Mbps Fast Ethernet and it runs both in half- and full- duplex mode using two pairs of
Category 5 cables.
The Switch also supports 2-Ports Gigabit Ethernet that runs in Auto-negotiation mode and 10Mbps Ethernet or 100Mbps Fast
Ethernet that runs both in half- and full- duplex mode and 1000Mbps Gigabit Ethernet runs in full-duplex mode using four pairs of
Category 5 Cables.
These RJ-45 ports are Auto-MDI type port. The Switch can auto transform to MDI-II or MDI-X type, so you can just make an easy
connection that without worrying if you are using a standard or crossover RJ45 cable.
There are additional two mini-GBIC ports for optional mini-GBIC/SFP modules.

LED Indicator:
Comprehensive LED indicators display the status of the Switch and the network (see the LED Indicators chapter below).
Fast Ethernet Ports (Port 1~48):
These ports support network speeds of either 10Mbps or 100Mbps, and can operate in half- and full- duplex transfer modes. These
ports also supports automatic MDI/MDIX crossover detection function gives true “plug and play” capability, just need to plug-in the
network cable to the hub directly and don’t care if the end node is NIC (Network Interface Card) or switch and hub.
Gigabit Ethernet Ports (Port 49~50):
The Switch is equipped with two Gigabit twisted pair ports, supported auto negotiable 10/100/1000Mbps and auto MDI/MDIX
crossover detection function. These two ports can operate in half-duplex mode for 10/100Mbps and full-duplex mode for
10/100/1000Mbps.
Note: When the port was set to “Forced Mode”, the Auto MDI/MDIX will be disabled.
mini-GBIC (SFP) Ports (Port 49~50):
The Switch is equipped with two mini-GBIC ports, supported optional 1000BASE-SX/LX mini-GBIC transceivers.
Port 49 and 50 are the same ports with the mini-GBIC no.49 and 50 ports, when the mini-GBIC transceiver is plugged in, the
device will activate mini-GBIC, and the RJ-45 port will be disabled.
Reset:
The Reset button is to reset all settings back to factory defaults.
Note: Be sure that you record the setting of your device, or else all settings will be erased when pressing the “Reset” button.
Rear Panel

AC Power Connector:
This is a three-pronged connector that supports the power cord. Plug in the female connector of the provided power cord into this
connector, and the male into a power outlet. Supported input voltages range from 100-240V AC at 50-60Hz.
