Chapter 3
Maintenance and Component Installation
This chapter provides instructions on installing and replacing main system components. To
prevent compatibility issues, only use components that match the specifications and part
numbers given.
Remove power from the system or node before installing or replacing components. Refer to
Section 3.1.
3.1 Removing Power
Use the following procedure to verify that power has been removed from the system or node.
This step is required when removing or installing non hot-swap components or when replacing
a non-redundant power supply.
System Power
1. Use the operating system to power down the system.
2. After the system has fully shut down, disconnect the AC power cord(s) from the power
strip or outlet. (If your system has more than one power supply, remove the AC power
cords from all power supply modules.)
3. Disconnect the power cord(s) from the power supply module(s).
Node Power
Power can be removed from each individual node by pushing the power button located at
the front of the node. A node that has been powered off will have its LED turned off (see
section 1.4).
