8.9. Connecting Power
The SPR receives, through its 15-pin D-type port, its power supply from the SDA.
In turn, the SDA connects to an external power adapter from where it receives
power. The SDA provides 48 VDC nominal power to the SPR (minimum of 30
VDC: maximum of 55 VDC).
Warning: If you are using an external antenna, ensure that you connect the
antenna before connecting the SPR to the power source.
Note: For a description of the procedure for connecting power to the SDA, see
Chapter 9, “Installing the SDA”.
