Noise on RZ Legacy Optics

Tech Note: TN0865
Product: RZ2, RZ5
Version: RZ2 < 3000, RZ5 < 2000
Date Added: 2009-09-28


RZ2s with serial number less than 3000 and RZ5s with serial numbers less than 2000 will sometimes boot in a state which prevents them from properly phase- locking to amplifier devices connected to the front panel legacy optical ports. Signals recorded from the front panel fiber optic ports will look like noise and the channel numbers might be shifted i.e. signals expected on one channel appear on a completely different channel.


Cycle power on the RZ device.
