    2 INSTALLATION AND OPERATION 2.1 INTRODUCTION This section outlines the methods required to install and operate the OSD2251E successfully. It should be studied carefully if damage to the equipment or poor results are to be avoided. This equipment has been fully tested prior to dispatch and is ready for immediate operation.

  • Page 10: Drawings And Dimensions

    2.2.2 DRAWINGS AND DIMENSIONS The OSD2251E is designed to be wall mounted onto a DIN-Rail (35mm top hat) fixture or by using 4 x M4 captivated screws (DIN Rail mount requires removal and flanges repositioned – see below). The unit dimensions (excluding connectors, SFPs, etc) is shown in Figure 3 below.

  • Page 11: Power Supply Connections

    2.2.3 LOCATION As with any electrical device, the OSD2251E should be placed where the switch will not be subjected to extreme temperatures, humidity, or electromagnetic interference. Specifically, the site selected should meet the following requirements:  The ambient temperature should be between -40°C to 75°C.

  • Page 12: Alarm Connection

    2.2.5 ALARM CONNECTION The OSD2251E has two monitoring alarm outputs: 1) Ring to Bus Alarm and 2) Temperature Alarm. The alarm connections and conditions for alarm outputs are as set out in Table 3. There are four pins on the 3.5mm terminal block used alarm output. Maximum ratings the OSD2251E relay can drive is 100mA @ 46V .

    2.3 OPERATION When using the OSD2251E for the first time, check that the unit is in good condition with no visible damage. Upon power up check that the indicators illuminate accordingly on power up (see Table 4). 2.3.1 CONNECTIONS For RJ45 connection use Category 5 (CAT5) or higher. Length should be no more than 100 meters.
  • Page 19 FIGURE 15: REDUNDANT RING CONNECTION Bus Operation To connect the OSD2251E in a bus configuration ports 3 and 4 must be used together with fiber SFPs. The remaining ports (ports 1 & 2) should be used to connect to your Ethernet devices (eg.

  • Page 20: Command Line Interface

    The Command Line Interface (CLI) is a useful tool for checking link status and debugging link connections. To enable the use of CLI the OSD2251E must be connected to a PC with a serial port and an appropriate cable as specified in section 2.2.6. Using a terminal emulation program such as Hyperterminal, a number of command lines specific to the OSD2251E can be implemented to check link/node status, ring/bus topology and enable/disable float backup.

  • Page 21: Command Line Functions

    COMMAND LINE FUNCTIONS There are a number of command line functions that enables the user to obtain running information of a single OSD2251E unit or the complete topology of the ring/bus network. This section explains the command lines and its functions.
