Installation Requirements Chapter 1: Introducing the 6800/7000 Series of Frames Installation Requirements The installation requirements for the 6800/7000 series of frames are shown in the table below: Depth from Surface Frame Rack Space FR-6801/FR-6801-1 A 1RU unit that requires 1.75 in. (44 mm) of standard 19 in. (483 mm) rack space. 11 in. (280 mm) FR-6804/FR-6804-1 A 2RU unit that requires 3.5 in. (88 mm) of standard 19 in. (483 mm) rack space. 11 in.
Chapter 1: Introducing the 6800/7000 Series of Frames Installation Requirements Frame Loading Limitations Leitch 6800/7000 series frames are designed to operate in an ambient temperature range of 0° to 50°C (32° to 122°F). No special provisions are necessary other than power loading limitations that should be considered upon installation.
Maximum Frame Loading Chapter 1: Introducing the 6800/7000 Series of Frames Maximum Frame Loading If the total loading exceeds either the power supply limitations or the maximum frame loading limited, then that frame configuration is not recommended. The 6801PS (Power Supply) should not be used in the FR-6804 frames. There is a limit on the amount of total module power consumption (excluding the power supply) allowable within a given frame.
Chapter 1: Introducing the 6800/7000 Series of Frames Maximum Frame Loading Allowable Frame Configurations Follow these steps to ensure that a particular frame configuration is within allowable power limits. 1. Using the figures listed in your frame requirements, calculate the total per rail loading requirements for the positive rail and the negative rail. The sum will be the total module loading requirement. 2.

Plug the other end of the main power cable into the studio power supply outlet.
Chapter 3: FR-6804/FR-6804-1 Frames Failure Conditions Failure Conditions If neither LED is illuminated, remove power to the fan tray unit immediately. Extended duration of this short circuit condition will cause damage to both the fan tray circuitry and the external power supply. To turn off the power to the fan tray, follow these instructions: 1. Pull the black locking pins on each end of the FR-6804(1) front panel until they snap out of position. These pins remain attached to the panel. 2.
Chapter 4 CF-6801 Cooling Frame Overview The CF-6801 is a one rack unit (1RU) frame fan tray with a high-airflow fan array. It provides redundant, low-noise cooling for up to two 2RU frames of equipment (4RU), or up to twenty 6800/7000 series modules. This fan array provides 40 cubic feet per minute (cfm) of airflow, evacuating from the frames below it, and exhausting into the rear of the rack. Installation Requirements The CF-6801 supplies forced air cooling for the power supply and the frame.
Chapter 4: CF-6801 Cooling Frame Overview The drawing below describes the output of the CF-6801 cooling frame. Note that 1RU of open rack space is required when the CF-6801 is used to cool two FR-6804 frames. CF-6801 85 W max. FR-6804(-1) 75 W max.

Chapter 4: CF-6801 Cooling Frame FR-6804(-1)/CF-6801 Installation 4. Arrange the FR-6804(-1) and the CF-6801 frames at the front and the back so that the vents are aligned. 5. Plug the main power cable into the left power receptacle in the back of the FR-6804(-1). 6. Plug the other end of the main power cable into the studio power supply outlet. After completing the installation procedure, verify that the CF-6801 is correctly installed: 1.
LEDs Chapter 4: CF-6801 Cooling Frame LEDs A green LED indicates that power is supplied to the unit, while a red LED indicates a failure sensed by a contact closure. There are five criteria for failure in the CF-6801, indicated by the LEDs and listed in the table below. See “Failure Conditions”, on page 22. LED Condition Function Over-Current Sensing (red) If one or more of the fans short out, this LED illuminates and the GPI closes.
Chapter 4: CF-6801 Cooling Frame Failure Conditions Failure Conditions Remove power to the fan tray unit immediately if both the red and green LEDs are extinguished as this indicates a short circuit failure condition. Extended duration of this condition will cause damage to both the fan tray circuitry and the external power supply. Follow the instructions to turn off the power to the fan tray: 1. Pull the black locking pins on each end of the FR-6804(-1) front panel until they snap out of position.

Chapter 8 7000PS Power Supply Module Overview The 7000PS is a universal input power supply capable of operating over the line input range of 90 to 265 VAC. The power supply produces two identical outputs of opposite polarity with a total output power of 10 W.
Chapter 8: 7000PS Power Supply Module Output Voltage Selection Output Voltage Selection Ouput voltage is controlled by selection of jumpers J1-J4 for positive voltage, and jumpers J5-J8 for negative output. Installing jumpers J2 and J4 connects the nominal 7 V ending to the output rectifier filter circuitry. This allows the power supply to be adjusted to 6 or 8 V output. Installing jumpers J1 and J3 connects the 13 volt winding to the output circuitry and gives a 13 V output.
