Power supplies for Blade enclosure

Power supplies for Blade enclosure

I've got a BL20p G3 blade that doesn't automatically power up upon insertion into the blade enclosure. I've checked the ILO settings, and the option to boot up is checked. I'm thinking it's a power issue, so I tried putting in 2 power supplies, and they don't become active. What am I doing wrong? Any help would be greatly appreciated, because I have little experience with this product.

Hi Pete

I had the same issue but sorted out after adding power supplies.
I had 3 blade enclosures and 8 power supplies (2 power enclosures )power supplies were in slot 1,2,4 and 5.
I had added 4 more power supplies and also upgraded the Firmware to the latest available.

Re: Power supplies for Blade enclosure

Pete,

what kind of power enclusre do you have? The one with 3U or the one with 1U?

In which slots did you insert those power supplies?

Re: Power supplies for Blade enclosure

The power enclosure is 1U. I just filled the remaining blade enclosure slot with a blade, and it won't power up properly. If I hold the button for 5 seconds it will start. Currently power supplies are in 1,2,4, and 5 position. So I added 2 power supplies to the power enclosure, and they don't seem to power on.

Pete,

why do you think, the power supplies won't getting active. What's the status of the LEDs of those power supplies?

Re: Power supplies for Blade enclosure

The LED's never light up. they are brand new, so the chances of them being bad are slim to none, but I'm going to try 2 other ones that i have.

Pete,

if nothing wae changed on the power enclsore the power supplies should power up and run permanently. You can configure them to just power up on demand but then they will even power up on insert for about 20 seconds and then go to hot-standby. The LED should blink in this mode. Sounds, you have a kind of defect either with the supplies or with the enclosure. But like Anand said it is a good idea to bring them all to the latest firmware, as the HP support asks you to do as well before any intervention.

Re: Power supplies for Blade enclosure

Ehm, just one stupid question, I know it's very simple but did you connect a power cable to the new slots of the power enclosure and are you sure you have power on both slots?

Yes.....each power supply needs to have it's only power connection in the back. Are slots 3 and 6 plugged in?

Re: Power supplies for Blade enclosure

Forgive me for not knowing much about this, as i was mistaken. it is a 3U not a 1U. It also has two bus bars (a,b).

Pete,

no problem, but I do not know much about the 3Us as I only use the 1U PEs. As I remember there are two different models. One model use 3 phase pwer, the second only 1 phase. And as I remember further those with 1 phase can only support a limited number of power supplies (I think 4). So even there is a slot, the power supplies won't work, because there are no connectors on the backplane.

As the eigth blade won't power up, you have a power shortage on power suplly 4 and 5. Only these power supplies deliver the power for blade 5 to 8. So I would recommend to exchange those power supplies one by one. But take care, your blades could crash. So shut down the servers if possible. If not, try to check the state of the supplies via the rack view of the ILO interface. For the 1U Units you get a short over view of the input and output settings.

I checked the status of the power supplies through the ILO, and everything is green and looks to be running.
