Working inside the compute node
To look at system information on the light path diagnostics panel on system board, remove the compute node cover and press the power button on the front panel. Review these guidelines before doing so.
The compute node might stop and loss of data might occur when internal compute node components are exposed to static electricity. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding systems when working inside the compute node with the power on.
Avoid loose-fitting clothing, particularly around your forearms. Button or roll up long sleeves before working inside the compute node.
Prevent your necktie, scarf, badge rope, or long hair from dangling into the compute node.
Remove jewelry, such as bracelets, necklaces, rings, cuff links, and wrist watches.
Remove items from your shirt pocket, such as pens and pencils, in case they fall into the compute node as you lean over it.
Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the compute node.
