Device Status LEDs and Ethernet Port LEDs

The device LEDs show information about current device status. When the device power up, the POWER/STATUS LED will show solid orange during power on process. Startup takes one minute approximately to complete, the LED will change to solid green. If you want to turn the device off and on again, we recommend you wait a few seconds between shutting it down and powering it back. The Ethernet LEDs show the status of each Ethernet port. Table 2 lists the name, color, status and description of each device LED.

Installing and Connecting the Device

This chapter describes how to connect cables and power to the device.

Before You Begin
Observe the following precautions to help prevent shutdowns, equipment failures and injuries:

Before installation, always check that the power supply is disconnected

• Ensure that the room in which you operate the device has adequate air circulation and that the room temperature does Not exceed 40˚C (104˚F)
• Allow 1 meter (3 feet) of clear space to the front and back of the device.
• Do not place the device in an equipment rack frame that blocks the air vents on the sides of the chassis. Ensure that enclosed racks have fans and louvered sides.
• Correct these hazardous conditions before any installation: moist or wet floors, leaks, ungrounded or frayed power cables, or missing safety grounds.

Connecting Power and Turn the Device On/Off

The AC/DC Power Adapter shipped with the device connects the device to earth ground when plugged an AC grounding-type power outlet. The device must be connected to earth ground during normal operation. To connect power to the device, plug the AC/DC power adapter into the DC power phone jet on the back panel of the device. Note: We recommend using a surge protector for the power connection. To power on the DSR-250 device, press the DC power switch on the rear panel to the on position. To power off the device, press the power switch to the off position.

Connecting the Device to a Network

This section provides basic information about physically connecting the DSR-250 to a network. To connect the necessary cables as shown in Figure 3.

1. Connect an RJ-45 cable from the port labeled WAN to the external router. The port WAN is pre-allocated to the WAN network segment.
2. Connect an RJ-45 cable from the port labeled LAN (1-8) to a switch in the LAN network segment.
3. Connect an RJ45-to-DB9 cable from the console port for CLI (Command Line Interface) management access.
   

Initially Configure the Device

The services router software is preinstalled on the DSR-250 device. When the device is powered on, it is ready to be configured. While the device has a default factory configuration that allow you to initially connect to the device, you must perform further configuration for your specific network requirements.

Using the WebUI

To use the WebUI, the workstation from which you are managing the device must initially be on the same subnetwork as the device.

To access the device with the WebUI:

1. Connect your workstation on the port labeled LAN (1-8), which is pre-allocated to the LAN.

2. Ensure your workstation is DHCP Client enabled or configured with a static IP address in the 192.168.10.0/24 subnet.
   Note: Disable pop-up blocking software or add the management IP address http://192.168.10.1 to your pop-up blocker’s allow list.

3. Launch your browser; enter the IP address for the LAN interface. (The factory default IP address is http://192.168.10.1), then press Enter.

4. Log on the Services Router Web Interface The default log on information is:
   Username: admin
   Password: admin
   

Using a Console Connection (RJ45-to-DB9 DCE)

The Services Router provides an serial port that enables a connection to a computer or terminal for monitoring and configuring the device. This port is a RJ-45 connector, implemented as a data communication terminal equipment (DCE) connection.
To use the console port connection, you need the following equipment:

1. A terminal or a computer with both a serial port and the ability to emulate a terminal.
2. A RJ45-to-DB9 RS-232 with female connector. (Already included in packing list)
3. If your Laptop or PC doesn’t have RS-232 connector, a converter is required.

Note: DSR-250 does not come with RS-232 converter and these must be purchased separately.

To establish a console connection:

1. Plug the RJ-45 connector of the supplied RJ45-to-DB9 cable directly to the console port on the Services Router.
2. Connect the other end of the cable to a terminal or to the serial connector of a computer running terminal emulation software. Set the terminal emulation software as following:
   • Baud rate: 115200
   • Data bits: 8
   • Parity: None
   • Stop bits: 1
   • Flow control: None
3. When you have correctly set up the terminal, having previously followed the instructions in section “Connecting Power and Turn the Device On/Off” then switch on your device. The boot sequence appears in the terminal.
4. Once the boot sequence completes, the command prompt is displayed, the device is ready to be configured.

Finalizing the Configuration

After initial setup, you should refer to the companion publications found in PDF format on the accompanying master CD for more infor-mation on how to begin to configure the DSR-250 device.
