Replacing OSN Server Modules

The procedure below describes how to replace the OSN server modules.

The OSN server modules are hot-swappable and can be replaced without powering down the device and thus, without disrupting other non-related OSN services (e.g., Gateway and/or SBC functionality) running on the device. In addition, if the device is installed with two HDMX modules and you need to replace or remove one, you can do so without powering down the device and thus, without affecting OSN services.

➢ To replace an OSN module:
1. Shut down the operating system running on the OSN server (through RDP or monitor and keyboard).
2. Gently and slowly pull the module's handle until you hear the first click sound; the handle is now partially pulled out and the module undergoes a shutdown sequence indicated by the slow-flashing Hot Swap Blue LED_blue.png LED on the module.
3. When the LED_blue.png LED stops flashing and is constantly lit, indicating that the shutdown sequence is complete, disconnect any cables that may be connected to the module.
4. Grip and gently pull the module's handle to slide the module out of the slot.
5. Hold the new OSN module in the correct orientation, as shown in the following figure, and gently insert the module into the slot, sliding it along the slot's guide rails until it makes contact with the card-edge connector located on the backplane.

6. Push the module's handle until it clicks firmly into the slot; the operating system on the OSN server starts up.
➢ To replace an HDMX module:
1. Shut down the operating system running on the OSN server (through RDP or monitor and keyboard).
2. Gently pull the module's handle until you hear the first click sound; the handle is now partially pulled out and the module undergoes a shutdown sequence, indicated by the slow-flashing Hot Swap Blue LED_blue.png LED on the module.
3. When the LED_blue.png LED stops flashing and is constantly lit, indicating that the shutdown sequence is complete, grip and gently pull the module's handle to slide the module out of the slot.
4. Hold the new HDMX module in the correct orientation, as shown in the following figure, and gently insert the module into the slot, sliding it along the slot's guide rails until it makes contact with the card-edge connector located on the backplane.

5. Push the HDMX module's handle until it clicks firmly into the slot.
6. On the OSN module, gently pull the module's handle until you hear two click sounds, indicating that the handle has been fully pulled out, and then push the handle all the way in again; the module undergoes a reset, indicated by the Hot Swap Blue LED_blue.png LED switching off.
