Product Overview

This section contains an overview and technical specifications of the D-Link DES-3226L switch.

The D-Link DES-3226L is a high-performance Fast Ethernet switch that provides 24 10/100 Mbps switched ports with two combo gigabit copper/Small Form Factor Pluggable (SFP) ports. The switched 10/100 Mbps ports are ideal for segmenting networks into small, connected sub networks for superior performance, enabling the most demanding multimedia and imaging applications over the network. The two fixed-in gigabit copper ports support 10/ 100/1000BASE-T speed. There are also two SFP ports that provide optional fiber gigabit uplinks. These SFP ports are associated with the gigabit copper ports, so that if the SFP ports are used, the gigabit copper ports are disabled.

General Precautions for Rack-Mountable Products

Observe the following precautions for rack stability and safety. Also, refer to “Installing in a Rack” on page 22 and the rack installation documentation accompanying the rack for specific caution statements and procedures.

z Systems are considered to be components in a rack. Thus, component refers to any system

as well as to various peripherals or supporting hardware.

Product Overview 15

Caution:

z Before working on the rack, make sure that the stabilizers are secured to the rack,

CAUTION: Installing systems in a rack without the front and side

stabilizers installed could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizers before installing components in the rack. After installing system/ components in a rack, never pull more than one component out of the rack on its slide assemblies at one time. The weight of more than one extended component could cause the rack to tip over and may result in serious injury.

extended to the floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joined multiple racks before working on the rack.

z Always load the rack from the bottom up, and load the heaviest item in the rack first. z Make sure that the rack is level and stable before extending a component from the rack. z Use caution when pressing the component rail release latches and sliding a component

into or out of a rack; the slide rails can pinch your fingers.

z After a component is inserted into the rack, carefully extend the rail into a locking position

and then slide the component into the rack.

z Do not overload the AC supply branch circuit that provides power to the rack. The total

rack load should not exceed 80 percent of the branch circuit rating.

z Ensure that proper airflow is provided to components in the rack. z Do not step on or stand on any component when servicing other components in a rack.

NOTE:

A qualified electrician must perform all connections to DC power and to safety

grounds. All electrical wiring must comply with applicable local or national codes

and practices.

Caution: CAUTION: Never defeat the ground conductor or operate the equipment in

the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

CAUTION: The system chassis must be positively grounded to the rack cabinet frame.

Do not attempt to connect power to the system until grounding cables are connected. Completed power and safety ground wiring must be inspected by a qualified electrical inspector. An energy hazard will exist if the safety ground cable is omitted or disconnected.

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside your system. To prevent static damage, discharge static electricity from your body before you touch any of the electronic components, such as the microprocessor. You can do so by periodically touching an unpainted metal surface on the chassis.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

1. When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component in your system. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.

2. When transporting a sensitive component, first place it in an antistatic container or packaging.

3. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads, workbench pads and an antistatic grounding strap.

Switch Description

D-Link's DES-3226L switch is a high port-density Layer 2 switch that combines ultimate performance with fault tolerance, security, and management functions with flexibility and ease-of-use.

The D-Link DES-3226L switch has a combination of 1000BASE-T ports and SFP ports that may be used in uplinking various network devices to the switch (including PCs, hu bs, and other switches) to provide a gigabit Ethernet uplink in full-duplex mode. The Small Form Factor Pluggable (SFP) combo ports are to be used with fiber-optical transceiver cabling in order to uplink various other networking devices for a gigabit link that may span great distances. These SFP ports support full-duplex transmissions, have auto-negotiation, and can be used with DEM -310GT (1000BASELX) and DEM-311GT (1000BASE-SX) transceivers.

NOTE:

The SFP combo ports on the switch cannot be used simultaneously with the corresponding 1000BASE-T ports. If both ports are in use at the same time (for example, port 25 of the SFP and port 25 of the 1000BASE-T), the SFP ports will take priority over the combo ports and render the 1000BASE-T ports inoperable.

for more information on Windows 2000 service packs.

Starting the Switch

1. Make sure that the switch console port is connected to a VT100 terminal or VT100 terminal emulator via the RS-232 crossover cable.

2. Locate an AC power receptacle.

3. Deactivate the AC power receptacle.

4. Connect the switch to the AC receptacle.

5. Activate the AC power receptacle.

When the power is turned on with the local terminal already connected, the switch goes through a power-on self-test (POST). POST runs every time the switch is initialized and checks hardware components to determine if the switch is fully operational before completely booting. If POST detects a critical problem, the startup procedure stops. If POST passes successfully, a valid executable image is loaded into RAM. POST messages are displayed on the terminal and indicate test success or failure. The boot process runs for approximately 60 seconds.

Initial Configuration

The initial simple configuration procedure is based on the following assumptions:

z The DES-3226L switch was not configured before and is in the same state as when you

received it.

z The DES-3226L switch booted successfully. z The console connection was established and the console prompt appears on the screen of a

VT100 terminal or terminal equivalent.

Installing the Hardware 27

The initial switch configuration is performed through the console port. After the initial configuration, you can manage the switch either from the already-connected console port or remotely through an interface defined during the initial configuration.

NOTE:

The switch is not configured with a default user name and password.

NOTE:All of the settings below are necessary to allow the remote management of the switch

through Telnet (Telnet client) or HTTP (Web browser).

Before setting up the initial configuration of the switch, obtain the following information from your network administrator:

z The IP address to be assigned to the management interface through which the switch is

managed.

z The IP subnet mask for the network. z The IP address of the default gateway.

Initial Configuration Procedure

You can perform the initial configuration using the D-Link Easy Setup Wizard or by using the Command Line Interface (CLI). The Setup Wizard automatically starts when the switch configuration file is empty. You can exit the wizard at any point by entering [ctrl+z]. The wizard sets up the following configuration on the switch:

z Establishes the initial privileged user account with a valid password. The wizard config-

ures one privileged user account during the set up.

z Enables CLI login and HTTP access to use the local authentication setting only. z Sets up the IP address for the management interface. z Sets up the SNMP community string to be used by the SNMP manager at a given IP

address. You may choose to skip this step if SNMP management is not used for this switch.

z Allows you to specify the management server IP or permit SNMP access from all IP

addresses.

z Configures the default gateway IP address.

Example Session

This section describes an Easy Setup Wizard session. The following values are used by the example session:

z IP address for the management interface is 192.168.1.100:255.255.255.0. z The user name is admin, and no password is needed. Type in admin and press Enter. z The network management system IP address is 192.168.1.10. z The default gateway is 192.168.1.1.

The setup wizard configures the initial values as defined above. After you complete the wizard, the system is configured as follows:

z SNMPv1/2c is enabled and the community string is set up as defined above. SNMPv3 is

disabled by default.

z The admin user account is set up as defined.
