Ensure system interlocks are established before CPU extraction.\u003c\/p\u003e\n\u003cp\u003eQ: How is IEEE 1588 time synchronization maintained during network interruptions?\u003c\/p\u003e\n\u003cp\u003eA: The module maintains local oscillator stability to continue time-stamping events during transient network sync losses. Upon restoration of the PTP (IEEE 1588) master clock signal, the module automatically re-synchronizes its internal clock to the network time reference.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Seat the UR9TA into the primary CPU slot of the Universal Relay chassis.
