NOTICE
Your storage system is designed to be powered on continuously. Most components
are hot swappable; that is, you can replace or install these components while the
storage system is running. However, the system requires that:
Front bezels should always be attached to ensure EMI compliance. Make sure you
l
reattach the bezel after replacing a component.
Each slot should contain a component or filler panel to ensure proper air flow
l
throughout the system.
Procedure
1. Wear ESD gloves or attach an ESD wristband to your wrist and the enclosure in
which you are installing the part.
2. Unpack the part and place it on a static-free surface.
3. If the part is a replacement for a faulted part, save the packing material to
return the faulted part.
Touch points are component locations where you can:
Grip the hardware to remove or install a component.
l
Open or close a latch.
l
Turn a knob to open, close, or adjust a component.
l
Standard touch point colors are terra-cotta (orange) or blue.
Note
Within this documentation, the color orange is used instead of terra-cotta for
simplicity.
