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.
Installing Transceivers into the Transceiver Ports
The Switch is equipped with 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. After the system is powered on, the LED will blink green to indicate that the system is booting up.
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
Figure 5 — Insert Tie Wrap into the Switch
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.

Installing the Redundant Power Supply (RPS)
The Redundant Power Supply (RPS) is designed to conform to the wattage requirements of D-Link’s Ethernet and Gigabit switches. It is an external RPS unit enclosed in solid metal case with sockets to connect AC or DC power sources on one end, and to connect to a switch’s internal power supply on the other end. The RPS provides a low-cost, simple solution to the problem of an inadvertent failure of the internal power supply of an Ethernet switch, which can result in the shutdown of that switch, the devices attached to its ports, or an entire network.
CAUTION: Do not connect the RPS to AC power before the DC power cable is connected. This might damage the internal power supply.
DPS-500A and DPS-500DC Redundant Power Supplies
This RPS (DPS-500A and DPS-500DC) can be connected to the Switch’s RPS port
using the DPS-CB150-2PS (HW: B1) DC power supply cord. It is important to
notice that the RPS can supply power to one or two DGS-3000 Switches at the
same time.
Figure 10 — Connecting two switches to the DPS-500A/500DC
The following section explains how to connect the RPS to the Switch.
- Disconnect the Switch from the main AC power source.
- Insert the 14-pin end of the DPS-CB150-2PS (HW: B1) DC power supply cord into the RPS and the 2-pin end into the receptacle of the RPS port on the Switch.
- Using a standard AC power cord, connect the RPS to the main AC power source. A green LED on the front panel of the RPS will illuminate to indicate a successful connection.
- Make sure that the ON/OFF toggle switch on the rear panel of the Switch is turned on.
- Re-connect the Switch to the AC power source and power on the RPS.
No configuration is needed in the Switch software for this installation.
Installing the RPS into a Rack-mount Chassis
DPS-800
The DPS-800 is a standard-size (1 standard unit in height) rack mountable unit
designed to hold up to two RPS units.
NOTE: This rack-mount chassis supports the following RPS units: DPS-500A and DPS-500DC.
