However, you must turn off the server before you perform any steps that
involve removing or installing adapter cables.
v
Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the server, 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 server and
operating system support hot-swap capability, you can remove or install the
component while the server 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.
v
When you are finished working on the server, reinstall all safety shields, guards,
labels, and ground wires.
System reliability guidelines
Use this information to understand what you need to do to ensure that the system
cooling and system reliability requirements are met.
To help ensure proper system cooling and system reliability, make sure that the
following requirements are met:
v
Each of the drive bays has a drive or a filler panel and electromagnetic
compatibility (EMC) shield installed in it.
v
Each of the power-supply bays has a power supply or a filler installed in it.
v
There is adequate space around the server to allow the server cooling system to
work properly. Leave approximately 50 mm (2.0 in.) of open space around the
front and rear of the server. Do not place objects in front of the fans. For proper
cooling and airflow, replace the server cover before you turn on the server.
v
You have followed the cabling instructions that come with optional adapters.
v
You have replaced a hot-swap fan within 30 seconds of removal.
v
You have replaced a hot-swap drive within 2 minutes of removal.
v You have replaced a failed hot-swap power supply within 2 minutes of removal.
v
You do not operate the server without the air baffles installed. Operating the
server without the air baffles might cause the device to overheat.
Handling static-sensitive devices
Use this information to prevent damage to the server and other electronic devices
from static electricity.
Attention: Static electricity can damage the server and other electronic devices. To
avoid damage, keep static-sensitive devices in their static-protective packages until
you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v
Limit your movement. Movement can cause static electricity to build up around
you.
v
Handle the device carefully, holding it by its edges or its frame.
v
Do not touch solder joints, pins, or exposed circuitry.
v
Do not leave the device where others can handle and damage it.
