Installation the D-Link DGS-2205 Green Switch

1.Before You Connect to the Network

The site where you install the Switch may greatly affect its performance. Please follow these guidelines for setting up the Switch.

• Install the Switch on a sturdy, level surface that can support at least 3 kg (6.6 lbs.) of weight. Do not place heavy objects on the Switch.

• The power outlet should be within 1.82 meters (6 feet) of the Switch.

• Visually inspect the power cord and see that it is fully secured to the AC power port.

• Make sure that there is adequate space for proper heat dissipation from and adequate ventilation around the Switch. Leave at least 10 cm (4 inches) of space at the front and rear of the Switch for ventilation.

• Install the Switch in a fairly cool and dry place 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.

• When installing the Switch on a level surface, attach the rubber feet to the bottom of the device. The rubber feet cushion the Switch, protect the casing from scratches, and prevent it from scratching other surfaces.

Mounting the Switch on the Wall

The DGS-2205 can also be mounted on a wall. Two mounting slots are provided on the bottom of the switch for this purpose. Please make sure that the front panel is exposed in order to view the LEDs. Please refer to the illustration below:

1. Mount the Nylon screw anchors into a cement wall.
2. Drive the T3 x 15L screws into the Nylon screw anchors.
3. Hook the mounting holes of the switch back on the screws.

Connecting the Switch

■DGS-2205 to End Node

End nodes include PCs outfitted with a 10, 100, or 1000 Mbps RJ-45 Ethernet Network Interface Card (NIC) and most routers. An end node can be connected to the Switch via a twisted-pair Category 3, 4, 5, or 5e UTP/STP cable. The end node can be connected to any of the ports of the Switch.

The Link/Act LEDs for each UTP port light green when the link is valid. The LED over the port label indicates a port speed of either 10/100 Mbps or 1000Mbps. A blinking LED on the bottom indicates packet activity on that port.

■Hub/Switch to DGS-2205

These connections can be accomplished in a number of ways using a standard Ethernet cable.

• A 10BASE-T hub or switch can be connected to the Switch via a twisted-pair Category 3, 4, 5, or 5e UTP/STP cable.
• A 100BASE-T hub or switch can be connected to the Switch via a twisted -pair Category 5 UTP/STP cable.
• A 1000BASE-T switch can be connected to the Switch via a twisted -pair Category 5e or better UTP/STP cable.

■Connecting To Network Backbone or Server

Any of the five Gigabit Ethernet ports are ideal for uplinking to a network backbone or network server.

Troubleshooting

●Why can´t I share my Internet connection to multiple computers when using my D-Link DGS-2205 switch?

If you are connecting directly to a Cable or DSL modem, you will need a router to “share” your Internet connection or a computer using ICS (Internet Connection Sharing) or Proxy. Switches and hubs do not allow you to share a single IP address to multiple computers.

Another alternative is to contact your ISP and purchase extra IP addresses for each additional computer.

●Does the DGS-2205 switch have an uplink port?

The DGS-2205 has Auto-MDI ports which automatically sense the type of cable being used (e.g. Crossover or Straight-through) and adjust themselves accordingly to pass data over the network.

●What is the maximum length of Category 3, 4 or 5 twisted pair cable that can be used between the DGS-2205 and other devices such as routers, switches, computers, etc.?

The maximum length of Category 3, 4 or 5 twisted pair cable that can be used between computers and other devices on a network is 100 meters or about 328 feet. Keep in mind that this is a theoretical limit. Usually, you will want to keep the distance between devices well below the limit.

D-Link IP Address Assignment(D-Link DES-3800 Series)

Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other
TCP/IP application (for example BOOTP, TFTP). The Switch’s default IP address is 10.90.90.90. You can change the default
Switch IP address to meet the specification of your networking address scheme.

des-3800-c

The Switch is also assigned a unique MAC address by the factory. This MAC address cannot be changed, and can be found by entering the command “show switch” into the command line interface, as shown below.

des-3800-a

The Switch’s MAC address can also be found from the Web management program on the Switch Information (Basic Settings)
window on the Configuration menu.

The IP address for the Switch must be set before it can be managed with the Web-based manager. The Switch IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the Switch must be known.

The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows:
Starting at the command line prompt, enter the commands.

config ipif System ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy

Where the x’s represent the IP address to be assigned to the IP interface named System and the y’s represent the corresponding subnet mask.

Alternatively, users can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z. Where the x’s represent the IP address to be
assigned to the IP interface named System and the z represents the corresponding number of subnets in CIDR notation.
The IP interface named System on the Switch can be assigned an IP address and subnet mask, and then be used to connect a management station to the Switch’s Telnet or Web-based management agent.

des-3800-b

In the above example, the Switch was assigned an IP address of 10.53.13.83 with a subnet mask of 255.0.0.0. The user may also use the CIDR form to set the address (10.53.13.83/8).

The system message Success indicates that the command was executed successfully. The Switch can now be configured and managed via Telnet and the CLI or via the Web-based management.
