2. Introduction 2. Introduction 2.1. Purpose Cellular telephone systems transmit signals in two directions between a base transceiver station (BTS) and mobile stations (MS) within the signal coverage area. If weak signal transmissions occur within the coverage area because of indoor applications, topological conditions or distance from the transmitter, extension of the transmission range can be achieved by means of an optical distribution system.
2. Introduction The ION is easily set-up and supervised via a graphical user interface (GUI). Remote units can be commissioned through the use of built-in test equipment. An autoleveling function compensates for the optical link loss making installation easy and quick. The entire system may be monitored remotely via an Andrew OMC. This platform uses SNMP protocol and is compliant to X.733 standard.
3. Commissioning 3. Commissioning Read and observe the health, safety, and property damage warnings as well as the description carefully to avoid mistakes and proceed step-by-step as described. Attention: Do not operate the unit without terminating the antenna connectors. The antenna connectors may be terminated by connecting them to their respective antennas or to a dummy load.
3. Commissioning 6. Notice: A spacing of 40 mm (1.58 inch) around the unit is required. 7. Notice: To ensure sufficient airflow when mounting the unit in enclosed spaces, two lid openings (one for the air inlet and the other for the air outlet) must be provided. Do not block these air inlets and outlets when mounting the unit. The size of each opening must equal at least 18 x 18 cm (>300 cm2). Make sure, too, there is no thermal short circuit between the air inlet and air outlet. 8.
3. Commissioning 3.1.3. Mounting Distance between RU and EU The Extension Unit has to be connected to the Remote Unit via the cable bridge that has to be ordered separately from the supplier. The length of the cable bridge determines the maximum mounting distance between the Remote Unit and the Extension Unit: Length 1200 mm 2000 mm 2500 mm Distance 585 mm / 23.03” 1385 mm / 54.52” 1885 mm / 74.21” Max.

4. Alarms and Troubleshooting 4. Alarms and Troubleshooting All alarms occurring can be checked via software at the Master Unit to where a message is transmitted when the software acknowledges a valid alarm. A new alarm message will not be repeated if the reason for the alarm is cleared or if the alarm continues. A new alarm message will be generated if the alarm is interrupted for at least five seconds after acknowledgement. Refer to the corresponding software documentation of the Master Unit for details.
5. Maintenance 5. Maintenance 5.1. General Read and observe chapter 1.2 Health and Safety. Caution: Rotating fans. Risk of injury in operation. Wear tight-fitting clothes and disconnect mains before connecting or replacing or cleaning the fan unit. Caution: The unit reaches high temperature in operation. Risk of burns by hot surface. Do not touch the unit before it has sufficiently cooled down. Due to the design of the Extension Unit the only component recommended to be replaced is the fan unit.
5. Maintenance 5.2. Replacing the Fan Unit Replacement of the fan unit is not required as a preventative measure. Only if an alarm indicates a malfunctioning of a fan, must the unit be exchanged. Note: Please observe that the fan unit can only be replaced as a whole. Do not remove the fans separately. Note: NEVER blow out the fan unit with compressed air. This would cause permanent damage to the unit. Read and observe chapter 1.2 Health and Safety as well as the instructions in section 5.
5. Maintenance 5.3. Cleaning the Heat Sink To avoid a malfunctioning of the Extension Unit, the heat sink should be cleaned in case of pollution. In order to prevent any damage, proceed as explained in the following. Note: Read and observe chapter 1.2 Health and Safety as well as the instructions in section 5.1 General before starting with the replacement procedure. Then, proceed as follows: 1. Switch off the Extension Unit.
