Working inside the node with the power on

When you are servicing a system node, you might need to turn on the node while the cover is off.

About this task

Attention: Static electricity that is released to internal components when the node is turned on might cause the node to halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the node with the power on.
You might be instructed to inspect, remove, or replace components when the enclosure or canister cover is removed. Follow these guidelines when you work inside a node:
  • Avoid wearing loose-fitting clothing on your forearms. Do not allow your clothing to hang inside the node.

    For example, ensure that long-sleeved shirts are buttoned before you work inside the node.

  • Remove jewelry, such as bracelets, necklaces, rings, cuff links, and loose-fitting wrist watches.
  • Remove items from your shirt pocket, such as pens and pencils, that might fall into the node as you lean over it.
  • Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the node.
