Installing or Replacing Server Components
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.
Installing or Replacing Server Components
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
Warning
Class 1 laser product.
