1. Introduction 1.1. Scope and Purpose of Document This handbook is for use solely with the equipment identified by the Axell Wireless Limited (AWL) Part Number shown on the front page. It is not to be used with any other equipment unless specifically authorized by AWL. This is a controlled release document and, as such, becomes a part of the Axell Wireless Total Quality Management System. Alterations and modification may therefore only be performed by Axell Wireless.
2. Safety Considerations 2.1. Earthing of Equipment Equipment supplied from the mains must be connected to grounded outlets and earthed in conformity with appropriate local, national and international electricity supply and safety regulations. 2.2.
2.5. Chemical Hazard Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes used in devices within equipment produced by Axell Wireless Ltd. Beryllium oxide dust can be toxic if inhaled, leading to chronic respiratory problems. It is harmless if ingested or by contact. Products that contain beryllium are load terminations (dummy loads) and some power amplifiers. These products can be identified by a yellow and black “skull and crossbones” danger symbol (shown above).
3. 60-228801 - WMATA Jackson Graham Building CRAS System The WMATA Jackson Graham Building CRAS System consists of the following equipment: Part No. 60-228703 Part No. 60-091705 Dual Fiber Optic Unit Dual Redundant PSU The Jackson Graham Building CRAS System provides the Primary Downlink to and receives the Primary Uplink signal from the Gallery Place Station CRAS System.

3.3.6. Dual Fiber Optic Unit 60-228703 DC Inlet The Dual Fiber Optic Unit 60-228703 is a standard module used in three different locations: the Jackson Graham Building, the Carmen Turner Facility and the Gallery Place Station.
3.4. Dual Redundant PSU 60-091705 Dual Redundant PSU 60-091705 is built into a 4U, 19” rack-mount case. The PSU case houses two mains driven PSU modules whose outputs are parallel combined using high power, low volt-drop diodes. This means that if either supply fails the other will seamlessly take over all power provision until the fault is rectified. Both supplies’ outputs are monitored and an alarm will become active should either module fail. 3.4.1.

5.12. RF Failover Switch Unit 60-228905 RF Failover Switch Unit 60-228905 is built into a 2U, 19” rack-mount case and receives both Primary (Jackson Graham Building) and Redundant (Carmen Turner Facility) Downlink signals from the Dual Fiber Optic Unit 60-228703; the RF level of the Primary Downlink is monitored by a power detector and if the signal falls below a preset threshold the unit automatically switches from the Primary to the standby Redundant path; the Uplink paths are switched at the same time.
The Automatic changeover of the transfer relay function can be overridden by selecting the Manual position of the switch labeled “AUTO / MANUAL” (annotated “S” in section 5.12.5.), the GREEN LED labeled “AUTO” (annotated “DD” in section 5.12.5.) is illuminated when in the Auto mode, the YELLOW LED labeled “MANUAL” (annotated “EE” in section 5.12.5.) will illuminate when the Manual mode is selected.
