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/or part
numbers given.
Installation or replacement of most components require that power first be removed from the
system. Please follow the procedures given in each section.
3.1 Removing Power
Use the following procedure to ensure that power has been removed from the system. This
step is necessary when removing or installing non hot-swap components or when replacing
a non-redundant power supply.
1. Use the operating system to power down the system.
2. After the system has completely 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).
3.2 Accessing the System
The SC218UTS-R1K62P features a removable top cover, which allows easy access to the
inside of the chassis.
Removing the Top Cover
1. If rack mounted, pull the system straight out until it locks with a click.
2. If the two optional screws are used to secure the cover to the chassis, remove them,
one from each side of the cover.
3. Press both release tabs at the same time to unlock the cover, and slide the cover to the
rear.
4. Lift the cover off the chassis.
To remove the system from the rack completely, press the locking tabs in the chassis rails
(push the right-side tab down and the left-side tab up) to continue to pull the system out past
the locked position.
