Installation Guidelines
This section will discuss the hardware installation guidelines that the user
must follow in order to properly and safely install this switch into the
appropriate environment.
- Visually inspect the power cord and see that it is fully secured to both the power connector, on the Switch, and the electrical outlet that supplies power.
- Install the Switch in a fairly cool and dry place within the acceptable operating temperature and humidity ranges.
- Install the Switch in a site free from strong electromagnetic field generators such as motors, vibration, dust, and direct exposure to sunlight.
Installing the Switch without a Rack
This section is used to guide the user through installing the Switch in an
area other than a switch rack. Attach the included rubber feet to the bottom
of the Switch. Take note that there should be marked blocks on the bottom of
the Switch to indicate where to attach the rubber feet. These markings are
usually found in each corner on the bottom of the device. The rubber feet
cushion the Switch, protecting the casing from scratches and preventing it
from scratching other surfaces.
Install the Switch on a sturdy, level
surface that can support the weight of the Switch. Do not place any heavy
objects on the Switch. The power outlet should be within 1.82 meters (6 feet)
of the Switch. Make sure that there is proper heat dissipation from and
adequate ventilation around the Switch. Leave at least 10 cm (4 inches) of
space at the front, sides, and rear of the Switch for ventilation.
Installing the Switch in a Standard 19” Rack
This section is used to guide the user through installing the Switch into a
switch rack. The Switch can be mounted in a standard 19″(1U) rack using the
provided mounting brackets. Fasten the mounting brackets to the sides of the
Switch using the screws provided.
Fasten the mounting brackets in any available open space in the rack using the
screws provided with the rack.
Installing Transceivers into the
Transceiver Ports
The Switch is equipped with Enhanced Small Form-factor Pluggable (SFP+) ports
that can be used to connect various other networking devices to this switch
that do not support the standard RJ-45 wiring connection. These ports are
generally used to connect this switch to optical fiber connections and can be
used to connect devices to the Switch over great distances. The maximum
distance that the RJ-45 wiring connection can reach is 100 meters. Fiber optic
connections can span several kilometers.
Power On (AC Power)
Plug one end of the AC power cord into the power socket of the Switch and the
other end into the local power source outlet.
Power Failure (AC Power)
In the event of a power failure, just as a precaution, unplug the power cord
from the Switch. After the power returns, plug the power cord back into the
power socket of the Switch.
Installing Power Cord Retainer
To prevent accidental removal of the AC power cord, it is recommended to
install the power cord retainer together with the power cord. With the rough
side facing down, insert the tie wrap into the hole below the power
socket.
Plug the AC power cord into the power
socket of the Switch.
Slide the retainer through the tie
wrap until the end of the cord.
Circle the tie of the retainer around
the power cord and into the locker of the retainer.
Fasten the
tie of the retainer until the power cord is secured.
Management Options
This Switch provides multiple access platforms that can be used to configure,
manage, and monitor networking features available on this Switch. Currently
there are three management platforms available which are described below.
Command Line Interface (CLI)
This Switch can be managed, out-of-band, by using the console port on the
front panel of the Switch.
SNMP-based Management
The Switch can be managed with an SNMP-compatible console program. The Switch
supports SNMP v1, SNMPv2c and SNMPv3.
Web User Interface (Web UI)
The Web UI can be accessed from any computer running web browsing software.
This management interface is a more graphical representation of the features
that can be viewed and configured on this Switch.
Connecting to the Console Port
The front panel of the Switch provides an RJ-45 console port to connect a
remote system for monitoring and configuring the Switch. To use the RJ-45
console port, the following equipment is needed:
- A terminal or a computer with both an RS-232 serial port and terminal emulation software.
- A console cable with a male DB9 connector on one end and an RJ-45 connection on the other.
To connect the RJ-45 console port on the Switch to the computer:
- Connect the male DB9 connector on the console cable (shipped with the Switch) to the RS-232 serial port on the computer running terminal emulation software then insert the RJ-45 connector into the RJ-45 console port on the front of the Switch.
To configure the terminal emulation software as follows:
- Select the appropriate serial port (COM1 or COM2).
- Set the data rate to 115200 baud.
- Set the data format to 8 data bits, 1 stop bit, and no parity.
- Set flow control to none.
Connecting to the Switch for the First Time
After successfully connecting to the Switch’s console port and the Switch was turned on, the boot-up procedure will be displayed, as shown below.
After the
Switch was successfully booted up, the username and password prompt will
appear. Both the default Username and Password is admin. Enter the username
and password and press ENTER after each entry.
NOTE: For security reasons,
it is highly recommended to configure a personal username and password for
this Switch
Logging into the Web UI
Supported Web browsers:
- Microsoft Internet Explorer 8 or above

To access the Web UI, open a standard web browser, enter the Switch’s IP
address into the address bar of the browser, and press the ENTER key. To
access the Web UI from normal LAN ports, the default IP address is
10.90.90.90, with a subnet mask of 255.0.0.0. When connecting to the Web UI of
