Chapter 4. Customer replaceable units
This chapter provides instructions for adding options to your server. Some
option-removal instructions are provided in case you need to remove one option to
install another.
Installation guidelines
Before you begin to install options in your server, read the following information:
v Become familiar with the safety and handling guidelines specified under
“Handling static-sensitive devices” on page 42 and read the safety statements in
“Safety information” on page 163.
v
You do not need to turn off the server to install or replace hot-swap power
supplies, hot-swap drives, hot-swap fans, Active PCI (hot-plug) adapters, or
hot-plug Universal Serial Bus (USB) devices.
v The orange color on components and labels in your server identifies hot-swap or
hot-plug component. You can install or remove hot-swap and hot-plug
components while the system is running, provided that your system is configured
to support this function. For complete details about installing or removing a
hot-swap or hot-plug component, see the detailed information in this chapter.
v The blue color on components and labels identifies touch points where you can
grip a component, move a latch, and so on.
v Make sure that you have an adequate number of properly grounded electrical
outlets for your server, monitor, and any other options that you intend to install.
v Back up all important data before you make changes to disk drives.
v

System reliability considerations
To help ensure proper cooling and system reliability, make sure that:
v Each of the drive bays has either a drive or a filler panel installed.
v Each of the power-supply bays has a power supply installed.
v For tower models, make sure that there is at least 50 mm (2 inches) of ventilated
space at the sides of the server and 100 mm (4 inches) at the front and rear of
the server.
For rack configurations, make sure that space is available around the server to
enable the server cooling system to work properly. See the documentation that
comes with the rack for additional information.
v
The server cover is in place during normal operation.
v The air-baffle cover over the microprocessors remains closed during normal
operation.
v A removed hot-swap drive is replaced within 2 minutes of removal.
v Cables for optional adapters are routed according to the instructions provided
with the adapters.
v A failed fan is replaced within 48 hours.
v
The server is turned off and the power cords are disconnected before you open
the air-baffle cover.
v The air-baffle assembly is always installed in the server except when you are
installing or removing the components that are located under the air-baffle cover.
