1. Introduction
The 26-port Managed Gigabit Ethernet Switches are standard L2 switches that meets all IEEE 802.3/u/x/z/ae
10 Gigabit Ethernet, Gigabit Ethernet, and Fast Ethernet specifications. The switches provide three 8-port
modular slots. Each slot can accommodate one 8-port module. A variety of modules is available for selection.
They include 10/100/1000M copper module, 100/1000M SFP module, Copper and SFP mixed modules, and
Fast Ethernet fiber modules. Different modules can be installed flexibly in one device rack. The system detects
the types of the installed modules and configures the modules automatically. With variety of modules and
flexibility of installation, the switches can meet most requirements of deployment of fiber networks no matter
they are Gigabit Ethernet base, Fast Ethernet base or even combination of both.
The switches provide two 10GBASE SFP+ slots on the back rear panel. The SFP+ slots can be installed with
10GBASE optical fiber transceivers for high bandwidth fiber connection. They are used as uplink ports to the
backbone networks. They also can be used as a high-bandwidth inter-connection between two switches and
support full wire speed forwarding between two switches.
The switches support Telnet CLI, Web GUI, SNMP and console CLI interface for switch management. The
network administrator can logon the switch to monitor and configure port operating mode, Quality of Service,
and powerful L2 switching functions such as VLAN, IGMP, RSTP etc. In addition, the switches are also
featured with powerful security functions such as SSH, HTTPS, IEEE 802.1x & MAC-based authentication,
and ACL control to make them suitable for office core applications.
The following figure illustrates the switch has 3 empty slots with no module installed.

2.1 Unpacking
The product package contains:
The switch unit
One AC power cord (AC powered model)
One 19”rack mounting kit
2.2 Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire and damage to the product, observe the following
precautions.
Do not service any product except as explained in your system documentation.
Opening or removing covers may expose you to electrical shock.
Only a trained service technician should service components inside these compartments.
If any of the following conditions occur, unplug the product from the electrical outlet and replace the part
or contact your trained service provider:
- The power cable, extension cable, or plug is damaged.
- An object has fallen into the product.
- The product has been exposed to water.
- The product has been dropped or damaged.
- The product does not operate correctly when you follow the operating instructions.
Do not push any objects into the openings of your system. Doing so can cause fire or electric shock by
shorting out interior components.
Operate the product only from the type of external power source indicated on the electrical ratings label. If
you are not sure of the type of power source required, consult your service provider or local power
company.

2.3 Installing Module
The steps to install a module are:
1. Unscrew and open the cover of the module slot.
2. Insert the module into the slot until it is plugged on the slot connector properly.
3. Screw the module on the front panel of the base chassis securely.

-19-
2.4 Removing the Module
The steps to remove an installed module from a base chassis are:
1. Unscrew the module first.
2. Loosen two screw brackets and pull them out as shown below:
3. Use the brackets as handles to pull the module out from the module slot connector.

-20-
4. Remove the module from the slot.
2.5 Mounting the Switch
Desktop Mounting
The switch can be mounted on a desktop or shelf. Make sure that there is proper heat dissipation from and
adequate ventilation around the device. Do not place heavy objects on the device.
Rack Mounting
Two 19-inch rack mounting brackets are supplied with the switch for 19-inch rack mounting.
The steps to mount the switch onto a 19-inch rack are:
1. Turn the power to the switch off.
2. Install two brackets with supplied screws onto the switch as shown in figure below.
After bracket mounting
