Installation guidelines
Before you begin, read the following:
v Read the safety information beginning on page vii and the guidelines in “Handling
static-sensitive devices” on page 30. This information will help you work safely
with the blade server and components.
v
You do not have to turn off the blade server or disconnect the BladeCenter unit
from power to install or replace any of the hot-swappable modules on the rear of
the BladeCenter unit.
v
Before you remove a hot-swappable blade server from the BladeCenter unit, you
must shut down the operating system on it by typing the
shutdown -h now
command or choosing the shut down option from your GUI. See “Turning off the
blade server” on page 4 for details. You do not have to shut down the
BladeCenter unit itself.
v Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the blade server or BladeCenter unit, open or
close a latch, and so on.
v
Orange on a component or an orange label on or near a component indicates
that the component can be hot-swapped. You can remove or install the
component while the blade server or BladeCenter unit is running providing the
blade server or BladeCenter unit and operating system support the
hot-swappable capability. Orange can also indicate touch points on
hot-swappable components. See the instructions for removing or installing a
specific hot-swappable component for any additional procedures that you might
have to perform before you remove or install the component.
