Well, as suspected, it turns out that adding additional power supplies, solved this issue.  I was able to install two more 110 volt power supplies.  After doing that, I've been able to boot up six of the servers, simultaneously, without issue. I haven't been able to test whether or not all eight servers will boot.  This is because my remaining two servers have other issues, and require more parts.  However, I have reason to believe that, once I get those parts, they, too, will boot.
I have eight M910 blade servers installed inside of an M1000E enclosure. I installed them, one by one, while systematically installing an operating system on each one. Now, I want to network them all together. However, for some reason, I can get no more than five of them to run, at the same time. Once the M1000E has been powered on, I start pressing the "on" buttons on each of the servers. I get a solid blue light for each of them, until I push the power button on the sixth server. When I push the power button on the sixth server, the power button blinks a few times, and then stops. If I try to turn it on, via the web-based CMC browser, I receive a message which states "Another action is being performed on this server. Try again". I can wait, for several minutes, and try again. However, I continue to get the same result. The power light blinks a few times, and then stops. However, if I turn off one of the running servers, and then try to turn on server six, server six starts up, with no problem. Then, when I try to turn on the other server, that I just turned off, it's power button blinks a few times, and won't turn on. This strange phenomenon seems to happen to any of the servers. It doesn't seem to matter which ones get turned off, or turned on. However, I can only get five of them to turn on, with no problem. Whenever I try to turn on a sixth, the power button just blinks a few times, and then stops. If I try to turn on a seventh one, the power button just blinks a few times, and then stops. Based on this behavior, I began to think that, perhaps, all of this is due to insufficient power from the power supplies. I'm using three 110v power supplies. However, each one is supposed to be capable of putting out 1350 watts. With five servers running, the M1000E shows that the entire system is only consuming about 1600 watts. So shouldn't the three power supplies be capable of providing enough power to power all eight blades? Each blade has 128 GB of RAM and four E7-4830 processors. I'll probably end up buying more 110v power supplies, and try running the M1000E with a total of six, instead of three. However, because each power supply can put out 1350 watts, and I have three of them, shouldn't that provide roughly 4050 watts of capability? If so, then why am I not able to turn on another server when power consumption is at 1600 watts? I should also note that, while looking at power configuration options, in the web-based CMC tool, I checked "Server Performance Over Power Redundancy". Shouldn't that ensure that these three power supplies are being used to their maximum potential? I look forward to hearing any suggestions that anyone may be willing to provide. I really need to be able to run all eight blades.  Thanks for your time.
M1000E Only Allows 5 Servers to Run at a Time.
