Removal and replacement procedures 33
These symbols, on power supplies or systems, indicate that the equipment is supplied
by multiple sources of power.
WARNING: To reduce the risk of injury from electric shock, remove all power cords to
completely disconnect power from the system.
Server warnings and cautions
Before installing a server, be sure that you understand the following warnings and cautions.
WARNING: To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all
times.
• Unplug the power cord from the power supply to disconnect power to the equipment.
• Do not route the power cord where it can be walked on or pinched by items placed against it.
Pay particular attention to the plug, electrical outlet, and the point where the cord extends from
the server.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
CAUTION: Do not operate the server for long periods with the access panel open or removed.
Operating the server in this manner results in improper airflow and improper cooling that can
lead to thermal damage.
Access panel
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
CAUTION: For proper cooling, do not operate the server without the access panel, baffles,
expansion slot covers, or blanks installed. If the server supports hot-plug components, minimize
the amount of time the access panel is open.
To remove the component:
1. Power down the server if performing a non-hot-plug installation or maintenance procedure ("Power
down the server" on page 27).
2. Extend ("Extend the server from the rack" on page 28) or remove ("Remove the server from the rack" on
page 29) the server from the rack.
3. Use the T-15 Torx screwdriver attached to the rear of the server to loosen the security screw on the hood
latch.
4. Lift up on the hood latch handle, and then remove the access panel.
To replace the component, reverse the removal procedure.
