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 20. 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 10 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. An exception to this rule are the DIMM clips and the
battery clip that are also touch points but not colored blue.
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.
Note: There are no hot-swappable components on the QS22 blade server. To
replace parts, you must turn off the blade server and remove it from the
BladeCenter unit.
