 Now, disconnect the USB and connect the Ethernet cable to the Stabilizer, as both won't fit at the same time.
 Stabilizer should connect to moquitto automatically, and you should see the MQTT settings pop up in the MQTT Explorer.

+## Installing the Pounder
+
+Remember that the Pounder is not fully supported in official QUARTIQ release; use the firmware from Hydra.
+
+Use ESD precautions; ensure that power is off (both barrel jack and PoE) before installing or removing the card.
+
+There are no guides for the Pounder connector. Line up the connectors with the pins and gently push in.
+
+SMA connectors should line up with the ones from Stabilizer; no pins should be visible from the sides of the Pounder; it's more obvious if the Pounder has the front panel already installed.
+
+## Testing the Pounder
+
+1. Set up the MQTT as described above.
+2. Using Mosquitto and MQTT Explorer, set the pounder ``out_channel`` parameters:
+* Frequency: 10e6 (10MHz)
+* Amplitude: 1.0
+   ![Pounder MQTT settings](../img/pounder_mqtt.png)
+3. Repeat the procedure for the other channel.
+4. Observe a sine wave of given frequency with an oscilloscope in the output channel.
