Installation, commissioning and testing process flow
Installation procedure comprises of the following steps:
• Receiving and unpacking the node.
• Verifying the cards/inventories as per the packing list or BOQ (Bill Of Quantity).
• Installing the chassis on the rack followed by cards in the respective slots of the chassis.
• Connecting grounding cable and power supply cables to the chassis.
• Connecting cables to the ports on the card.
The commissioning is the formal handover of the operational and maintenance responsibility for the end-product from the vendor to the operator. The process comprises of operation and performance qualification and includes environment compliance checks, verification of personnel protection equipment and qualification of containment systems.
The system level tests are required to be performed with the nodes in a working network. After commissioning the node, system level tests are done with the nodes that are cabled together in a working network. During the testing process, various forms must be filled to record system data and test results.
