Which is PS2 on the BACK of a catalyst C9500-16-E switch

I have a pair of Cisco C9500-16X-E switches. Both are showing alarms on PS2. Is it common with Cisco to always assume that the order of the power supplies will go from left to right? So PS1 and then PS2. I have not been able to find any simple documentation that lays this out from Cisco.

- Usually , yes , but you could unplug 'a-the' not working one and check the logs to see which is then being denoted (name). Usually one which has a green led can be considered safe and operational (better not to test with that...)

We were having some issues where on the back of each power supply the LED status was green on both. Everything on the switches are labeled well except the power supplies. I finally found documentation on the switches that Cisco will 9 times out of 10 put power supply 1 on the far left and go up accordingly moving to the right.
