I am trying to install a Fusion ioMemory SX350 card into a C420-M3 running BIOS v1.5(9)a. The PCIe card works, but it's operating at the default power of 24.75W, and the documentation indicates that it can provide better performance if it can use up to 75W. I have the ioMemory command to have the card increase the power, but the documentation indicates that this could cause damage to the server if it can't support it. Thus, I want to confirm things before making such changes.
The ioMemory SX350 is installed in a vSphere server, and the VMKernel.Log file indicates that the C420 isn't reporting back how much power the slot can provide. Here's the log entries:
vmkernel.log:2019-03-05T21:23:28.905Z cpu27:66483)<6>fioinf ioDrive 0000:43:00.0: PCIe Slot reported power limit: 0mWatts vmkernel.log:2019-03-05T21:23:28.905Z cpu27:66483)<6>fioinf ioDrive 0000:43:00.0: Warning! PCIe Slot reported power 0mWatts is less than product minimum power 13000mWatts vmkernel.log:2019-03-05T21:23:28.905Z cpu27:66483)<6>fioinf ioDrive 0000:43:00.0: PCIe Adapter power limit: 25000mWatts vmkernel.log:2019-03-05T21:23:28.905Z cpu27:66483)<6>fioinf ioDrive 0000:43:00.0: PCIe Adapter power Throttle point: 24750mWatts
I've looked at every C420-M3 document I can find, but nowhere does it indicates the maximum power provided by a PCIe slot, and at power-up, as you can see above, it indicates the power limit is 0mW. The card is installed in Slot 7.
If someone can please indicate the maximum PCIe slot power supported on a C420-M3, I'd sincerely appreciate it.

Hello, I just came across the Cisco Transport Gateway, but I can't find a SKU or cost for it. Is it free/included with a SmartNet Support Agreement? For those at Cisco, this might be a good thing to include in the FAQ...especially if it's free! Thank you! Luis

Hello, I'm relatively new to UCS, so I thought I'd learn by upgrading our lab UCS system from 2.1(1a) to 2.1(3a). I first downloaded the firmware files to the FI's without any issues, and then I launched Firmware Auto Install. Everything was going great until the VERY last step, and it's stuck there, at 94% complete. When I look at FSM tab for each of the FI's, they show as being completed. I also rebooted each FI, one-by-one, allowing the cluster to become healthy again before rebooting the next, but without any luck...still stuck at 94%. Attached is a screenshot showing the upgrade status. When I log into each FI, they both show version 2.1(3a), and cluster state is healthy. So, it's as if the final Activate just didn't register back, or something. Given both FI's are showing (within UCSM and CLI) the updated code revision for both running and startup, is the thing to do at this point to just power cycle BOTH of the FI's at the same time, with the thought that the FSM "state" will be cleared? If not, what is the proper procedure to clear this? Additionally, the FI's are both 6248's. Thank you for whatever assistance you can provide. Sincerely, Luis
