STREAKER INSTALLATION AND TESTING
Summary:
This procedure provides instructions for installation and testing of the Streaker module.
Note:
For a detailed description of Streaker (STK) module use, refer to Soneplex
Streaker Module Installation Instructions, listed under Related Publications at the
beginning of this manual.
Caution:
Because of the height of the battery holders, use care when sliding the module
into the chassis. To prevent damage to the Streaker module or adjacent modules, insert the
card straight into the chassis guides without bending or forcing the module into position.
1. Remove the Streaker module from its protective packaging.
2. Following the polarity markings on the battery holders, install four fresh AAA alkaline
batteries in the battery holders on the PC board.
3. Press the top of the voltage switch as shown in Figure 571-1 to select BATTERY (onboard)
operation, or press the bottom to select –48 VOLT FEED. (Dropping resistors and a zener
diode reduce the –48 VDC to approximately 6 VDC before it is applied to the indicators. In
addition, the –48 VDC input line is protected by a 0.5 amp fuse on the PCB.)
4. Align the card edges of the module with the mounting slot card guides, then slide the
module into a chassis slot until it contacts the backplane connector.
5. Use the ejector lever to seat the module in the connector. If difficulty is experienced when
inserting or seating this module, remove the module and check that the batteries are
properly seated in the holders; also check for other obstructions or misalignment in the
chassis.
6. Refer to Figure 571-2. When the module is seated, press the LMP TEST (lamp test)
pushbutton switch; all front panel indicators should light yellow. If the indicators do not
light, check that the batteries are installed properly or (if you have selected –48V) replace
the module.
Stop! You have completed this procedure.
