Chapter 5. Installing and removing replaceable units
This chapter provides instructions for replacing units on the blade server.
Replaceable units are components, such as memory modules, the hard disk drive,
and I/O expansion cards. (Some removal instructions are provided in case you
need to remove one replaceable unit to install another.)
The following replaceable units are supported:
v Battery
v
IDE hard disk (one only)
v The bezel assembly (control panel)
v
InfiniBand cards (optional)
Installation guidelines
Before you begin, read the following information:
v Read the safety information beginning on page vii and the guidelines in “Handling
static-sensitive devices” on page 40. This information will help you work safely
with the blade server and options.
v
Read the information in the BladeCenter QS20 Installation and User's Guide .
v Back up all important data before you make changes to disk drives.
v
Have a small flat-blade screwdriver and a Phillips screwdriver available.
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-swap modules on the rear of the
BladeCenter unit.
v Before you remove a hot-swap blade server from the BladeCenter unit, you must
shut down the operating system by typing the shutdown -h now command. If the
blade server was not turned off, press the power-control button (behind the
blade-server control-panel door) to turn off the blade server. 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, which means that if the blade server or
BladeCenter unit and operating system support hot-swap capability, you can
remove or install the component while the blade server or BladeCenter unit is
running. (Orange can also indicate touch points on hot-swap components.) See
the instructions for removing or installing a specific hot-swap component for any
additional procedures that you might have to perform before you remove or
install the component.
System reliability guidelines
To help ensure proper cooling and system reliability, make sure that:
v The ventilation holes on the blade server are not blocked.
v
Each of the blade bays on the front of the BladeCenter unit has a blade server or
filler blade installed. Do not operate the BladeCenter unit for more than 1 minute
without a blade server or filler blade installed in each blade bay.
v
You have followed the reliability guidelines in the documentation that comes with
the BladeCenter unit.
