https://community.extremenetworks.com/t5/extremeswitching-vsp-fabric/ers-4950gts-pwr-stack-issues/m-p/90912#M1804 We recently installed stacks of the 4950's and over the past few weeks they are repeatedly failing and breaking to form individual switch units. The current spec is HW: 11, FW: 7.5.0.2, SW: v7.5.0.007.<BR /> Spanning tree and SLPP are both configured on units. There is minimal end user traffic as these are school sites with the bare minimum staff at this time.<BR /> Any ideas would be appreciated.<BR /> <BR /> Thanks.
