6: Maintenance and Upgrade Procedures

Removing or Replacing a System Blade From the IRU

The blades installed in your SGI Altix 450 can generally be removed from or installed in an IRU without powering down the entire system. However, the operating system should be halted and the power to the IRU should be shut down in most cases. Note that the IA blade holding your system disk(s) should never be removed without backing up and gracefully powering down the unit.

Removing and Replacing a Compute/Memory Blade

Use the following information and illustrations to remove and replace a compute/memory blade from the host IRU:

1.Open the front door of the rack and access the IRU blade slated for replacement.

2.Move the blade’s retention tab gently to the left to disengage the locking tab. Be careful not to use too much force as the tab is breakable.

3.Pull the blade’s retention tab outward until it is fully extended, see Figure 6-8.

4.Slide the blade outward by pulling the bottom ring gently out.

5.Remove the blade completely from the IRU and place it on an anti-static work surface or in anti-static packaging.

6.Slide the new blade carefully into the IRU slot until seated in the slotting mechanism.

7.Carefully push the retention tab back into place so that the blade is seated and locked down, see Figure 6-9 for an example. Note that pushing in the tab fully seats the blade (moves it deeper into the IRU) and locks it in place.

8.Restart the IRU or system.
