Create a CMR to replace the hardware. The CMR should be approved by a technology team manager and the manager of the infrastructure team. Work with your manager to schedule a time for the hardware replacement that will have minimal impact on the majority of CallTower customers.
Ensure that the person replacing the hardware has access to the production data center. Replace the hardware at the approved time on the CMR.
Test to ensure that the hardware replacement is working as expected.
