I have 2 HP 2920 switches and they aren't stacking as I'm expecting.
Both models are the J9729A, however one is Aruba branded and one is the original HP brand. Everywhere I read this shouldn't be an issue, and the Aruba rebrand was simply that - a rebrand with no technical change.
Both switches are detecting the stacking module in the rear - both have the module light lit. However there doesn't appear to be a link between the switches as the port 1 and/or port 2 lights are not lit. As well running
show stacking detail shows both ports as inactive. I've tried connecting the stacking ports in all combinations 1>1 , 1>2 , 2>1 and 2>2.
Stacking is enabled on both, and I've tried following the procedures here with no luck. http://h22208.www2.hpe.com/eginfolib/networking/docs/switches/WB/15-18/5998-8156_wb_2926_atmg/content/ch06s02.html
I've tried firmwares 16.03.0003, 16.03.0007, and 16.05.0007 (Latest).
I've now tried doing an
erase all and
stacking factory-reset on both, then powered on one switch fully, entered
stacking set-stack, then the other. Still not detecting the link and both switches are acting as their own Commander.
Do you have any idea what could be going on here?
