C3000, C7000, interconnects, mezzanine mapping, racking a HP BladeSystem
One of the things I’ve seen a lot of is improper racking of HP BladeSystems. Sometimes people don’t take the time to RTFM and end up putting the whole thing together wrong in the rack. You’d think this wouldn’t be possible but it’s not that hard to do.
Two major things stand out wrong when racking an HP BladeSystem.
- People try and rack the HP BladeSystem while it’s fully populated with blades and interconnects and weighs well over a few hundred pounds. This is the quickest way to destroying your blade chassis by dropping it on the floor.
- After the blade is racked, people just put interconnects into any bay they want in the back without paying any regard to how the bays map to the mezzanine slots on the blades themselves.
What are the answers to these issues? Simple. For #1, you should completely dissassemble the BladeSystem down to every last piece. There are picture based instructions that come with the BladeSystem which make this very easy to do. Once it’s completely in pieces, then you can rack the empty cage fairly easily with the help of one other person. Then once it’s secured in the rack you can start to put it back together again. This is a lot easier than carrying it fully populated and your back will thank you for this.
For #2, go to HP’s website and follow the instructions regarding the mezannine mappings for the C7000 or C3000 (depending on what you’re using) BladeSystem. Then you can end up putting the interconnects in the right bays and your BladeSystem won’t give you a bunch of errors on boot up!
