Color-Coded Touch Points

This server has color-coded touch points that indicate thumbscrews and latches on replaceable and hot-swappable components.

•Hot-swappable components have green plastic touch points, which include the internal cooling fans and the power supplies. (Exceptions are the drive trays on the front panel, which are hot-swappable but not green).

•Some replaceable but non-hot-swappable components have light-blue plastic touch points, which include PCIe risers, PCIe slots, and the fan tray.

Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029
