The method includes writing PLD configuration data to a nonvolatile memory and directing a signal control device external to the PLD to hold system control signals in the network element at a predefined state irrespective of direction by the PLD. The method includes loading the PLD configuration data from the nonvolatile memory into a PLD configuration memory in the PLD, while the signal control device holds the system control signals at the predefined values. The method includes directing the signal control device to release the holding the system control signals, so that the PLD directs the system control signals, responsive to completion of the loading the PLD configuration data into the PLD configuration memory. A network element is also provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Live system upgrade","description":"A method for upgrading a programmable logic device (PLD) in a network element is provided.
