No I am not sure about this. I have seen cases where it works but there also times it gives out battery testing alerts too. So I would not recommend this as it does not show up compatible in Parts Guide.  In a gist, it can replace but its not compatible. UL1st Edition makes it compatible from which I can say that it can replace. However, difference in W is something I am not sure that How it would impact, if any.
Hi,  Unfortunately I do not have much knowledge about the EMC Clariions but let me try out this forum perhaps the answer is simple. We have two clustered Clariion systems, a clustered CX4-120 and and a clustered CX3-10c, by clustered I actually mean a primary location that is replicated to a secondary location.  Here is the problem, the CX4 is not used anymore and the CX3 will be out of service in a couple of months, there is no support on the CX3. The CX3 has both standby power supplies faulted and the idea is to replace these with the ones from the CX4.  I can hear you think, IDIOT but who am I tell you otherwise [IMAGE] From what I can see the standby power supplies are the same, perhaps the one from the CX4 has more power (A) but the output is the same.  Here comes the question(s): - Can I use the SPS from the CX4 in the CX3 - What is the procedure to replace these with the systems online
Replace standby power supply from cx4 to cx3
