I've got 460-24t switches claiming they have 1gb of RAM, and 460-48t claiming they have 512mb. Is this normal, and if so, why do the "bigger" switches have less RAM?
I can't find an official spec sheet anywhere that lists the RAM.
You should have 1GB of RAM on any x460.
I would recommend you to open a case with GTAC to investiguate further why your (some?) 48 ports report 512MB.
Do I understand correctly that you are saying that at least 2 x460-48 are having the same issue, and they are running different EXOS version?
I'm not sure how many we have off-hand (I'm not at work right now), but of the two 48t's I've checked, one is 15.3.3.5 p1-3 and the other one is 15.5.1.6
