•

To help avoid damaging your system, be sure the voltage selection Switch (if provided) on the power supply is set to match the power available at your location:

– 115 volts (V)/60 hertz (Hz) in most of North and South America and

some Far Eastern countries such as South Korea and Taiwan – 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan. – 230 V/50 Hz in most of Europe, the Middle East, and the Far East.

• Also be sure that attached devices are electrically rated to operate with the

power available in your location.

• Use only approved power cable(s). If you have not been provided with a power

cable for your system or for any AC-powered option intended for your system, purchase a power cable that is approved for use in your country. The powe r cable must be rated for the product and for the voltage and current marked on the product's electrical ratings label. The voltage and current rating of the cable should be greater than the ratings marked on the product.

• To help prevent an electric shock, plug the system and peripheral power cables

into properly grounded electrical outlets. These cables are equipped with threeprong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a 3-wire cable with properly grounded plugs.

• Observe extension cable and power strip ratings. Make sure that the total

ampere rating of all products plugged into the extension cable or power strip does not exceed 80 percent of the ampere ratings limit for the extension cable or power strip.

• To help protect your system from sudden, transient increases and decreases in

electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).

• Position system cables and power cables carefully; route cables so that they

cannot be stepped on or tripped over. Be sure that nothing rests on any cables.

• Do not modify power cables or plugs. Consult a licensed electrician or your

power company for site modifications. Always follow your local/national wiring rules.

• When connecting or disconnecting power to hot-pluggable power supplies, if

offered with your system, observe the following guidelines:

– Install the power supply before connecting the power cable to the power

supply. – Unplug the power cable before removing the power supply. – If the system has multiple sources of power, disconnect power from the

Safety Instructions (continued)

General Precautions for RackMountable Products

• Observe the following precautions for rack stability and safety. Also refer to the

rack installation documentation accompanying the system and the rack for specific caution statements and procedures.

• Systems are considered to be components in a rack. Thus, "component" refers

to any system as well as to various peripherals or supporting hardware.

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.

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

rack, 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.

vii

D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch

Safety Instructions (continued)

• Always load the rack from the bottom up, and load the heaviest item in the rack

first.

• Make sure that the rack is level and stable before extending a component from

the rack.

• 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.

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

position, and then slide the component into the rack.

• 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.

• Ensure that proper airflow is provided to components in the rack.

• Do not step on or stand on any component when servicing other components in

a rack.

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

The 16-port DGS-1016D and 24-port DGS-1024D Switches provide dedicated 10, 100 or 1000 Mbps Ethernet bandwidth on each port. The ports will automatically detect the speed, duplex and MDI/MDIX status of the device it is connecting to, and adjust these settings accordingly. The Switch ports can be used to network computers, printers, servers, routers, other switches or any device equipped with an Ethernet port. For best performance, use Category 5 or better Ethernet cabling.

This stand alone Switch is very easy to set up. There is no network management is required; simply power on the Switch and connect the cables.

However, please keep in mind that the standard rules of available Ethernet cable length from one device to another which cannot exceed 100 meters (or 300 feet).

Switch Features

The DGS-1016D 16-Port and DGS-1024D 24-port Switches do not require any management. Both Switches are designed for easy installation, flexibility and high performance. Connect devices to the Switch as the scale and volume of network traffic increases.

Gigabit Ethernet Technology

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet. Since it is compatible with all 10-Mbps and 100-Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company’s existing investment in hardware, software and trained personnel.

The increased speed and extra bandwidth offered by Gigabit Ethernet is necessary to coping with the network bottlenecks; more computers and their bus speeds getting faster, and more applications generate more traffic in the network. Upgrading key components, such as your backbone and servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed up the traffic between your subnets.

Gigabit Ethernet supports video conferencing, complex imaging and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC’s are able to perform 10 times the number of operations in the same amount of time.

802.1p and QoS

The DGS-1024D and DGS-1016D Switches support 802.1p priority queuing Quality of Service. The implementation of QoS (Quality of Service) and benefits of using 802.1p priority queuing are described here.

Advantages of QoS

QoS is an implementation of the IEEE 802.1p standard that allows network administrators a method of reserving bandwidth for important functions that require a large bandwidth or have a high priority, such as VoIP (voice-over Internet Protocol), web browsing applications, file server applications or video conferencing. Not only

can a larger bandwidth be created, but other less critical traffic can be limited, so bandwidth can be saved. The Switch has separate hardware queues on every physical port to which packets from various applications are mapped to and assigned a priority. The illustration below shows how 802.1P priority queuing is implemented on the Switch. The eight IEEE 802.1P priority levels defined by the standard are mapped to the four class queues used in the Switch.

Mapping QoS on the Switch

The picture above shows the default priority setting for the Switch. Class-3 has the highest priority of the four priority queues on the Switch. In order to implement QoS, the user is required to instruct the Switch to examine the header of a packet to see if it has the proper identifying tag tagged. Then the user may forward these tagged packets to designated queues on the Switch where they will be emptied, based on priority.

"The DUT support strict mode for 802.1p QoS. The untagged pkt will follow the priority 0 to work (i.e. class 1)."

Understanding QoS

The Switch has four priority queues. These priority queues are labeled as 3, the high queue to 0, the lowest queue. The eight priority tags, specified in IEEE 802.1p are mapped to the Switch's priority tags as follows:

• Priority 0 is assigned to the Switch's Q1 queue.

• Priority 1 is assigned to the Switch's Q0 queue.

• Priority 2 is assigned to the Switch's Q0 queue.

• Priority 3 is assigned to the Switch's Q1 queue.

• Priority 4 is assigned to the Switch's Q2 queue.

• Priority 5 is assigned to the Switch's Q2 queue.

• Priority 6 is assigned to the Switch's Q3 queue.

• Priority 7 is assigned to the Switch's Q3 queue.

The Switch uses strict priority for Scheduling. Strict priority-based scheduling, any packets residing in the higher priority queues are transmitted first.

D-Link Green Technology

• IEEE 802.3az Energy-Efficient Ethernet (EEE): It is the first standard in the history of Ethernet to address

proactive reduction in energy consumption for networked devices. The IEEE 802.3 EEE standard defines mechanisms and protocols intended to reduce the energy consumption of network links during periods of low utilization, by transitioning interfaces into a low-power state without interrupting the network connection.

• EEE+:

• D-Link provides an EEE+ function allowing the user to reduce

energy when the device is at low utilization and the link partner is a non-EEE compliance switch.

• By default, the EEE+ function is disabled. Users can

manually turn on the EEE+ function by the switch on the front panel to enable power savings.

• Power Saving Technology:

• Power saving by link status.

If there is no link on a port, such as when there is no computer connected to the port or the connected computer is

powered off, D-Link’s Green Technology will enter a "sleep mode", drastically reducing power used for that port.

• Power saving by cable length: 0~20m, 21~100m.

D-Link’s Green Technology detects the length of connected Ethernet cable and adjusts power usage accordingly without affecting performance. This way, a port connected to a 20m cable only uses as much power as it needs, instead of using full power, which is only needed for 100m cables.

Front-Panel Components

On the front panel of the Switch you will see the following.

• LED status indicators

• 16 Auto-Negotiating 10/100/1000Mbps ports on the DGS-

1016D

• 24 Auto-Negotiating 10/100/1000Mbps ports on the DGS-

1024D

• EEE+ on/off switch: By default, the EEE+ mode is disabled.

LED Indicators

The LED indicators of the Switch include a Power status indicator and Link/Act/Speed indicator for each port. When the Switch is powered on or restarted, it initiates a diagnostics function as part of the boot up process. The Link/Act/Speed indicators are also used to display Cable Diagnostics information when the Switch boots up.

LED Indicators

Cable Diagnostics

When the Switch is booted up (when the Switch is first powered on), the Cable Diagnostics function is initialized and run. The Cable Diagnostics function will detect two common faults in an Ethernet cable connecting the Switch to a remote network device: an open circuit (a lack of continuity between the pins at each end of the Ethernet cable or a disconnected cable), and a short circuit (two or more conductors short-circuited). Any of these common cable faults will be detected by the Cable Diagnostics function and the LEDs will display the results of the Cable Diagnostics function as follows:

Open or Short circuit

- Link/Act/Speed: Amber

Cable Connection in good status

- Link/Act/Speed: Green

During the diagnostics, each port is scanned to determine if the Ethernet cable and connectors is in good working order. During the diagnostics process the LED for each port blinks green in sequential order. If a cable fault is detected, the corresponding port’s Link/Act/ Speed LED will light amber. The Switch then goes for normal operation.

NOTE: the Cable Diagnostics function does not detect the length of Ethernet cabling. Remember that the length of cabling between two Ethernet devices may not exceed 100 meters (or 300 feet).
