Escala BL460 - Problem Determination and Service Guide
• 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 and operating
system support hot-swap capability, you can remove or install the component while the
blade 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.
• When you are finished working on the blade server, reinstall all safety shields, guards,
labels, and ground wires.
4.1.1 System reliability guidelines
Follow these guidelines to help ensure proper cooling and system reliability.
•
Verify that the ventilation holes on the blade server are not blocked.
• Verify that you are maintaining proper system cooling in the unit.
Do not operate the Bull Blade Chassis - Enterprise without a blade server, expansion
unit, or filler blade installed in each blade bay. See the documentation for your Bull
Blade Chassis - Enterprise for additional information.
•
Verify that you have followed the reliability guidelines for the Bull Blade Chassis -
Enterprise.
• Verify that the blade server battery is operational. If the battery becomes defective,
replace it immediately, as described in “ Removing the battery ” on page 224 and
“ Installing the battery ” on page 225 .
4.1.2 Handling static-sensitive devices
Attention:
Static electricity can damage the blade 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:
• Limit your movement. Movement can cause static electricity to build up around you.
•
Handle the device carefully, holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed circuitry.
•
Do not leave the device where others can handle and damage it.
• While the device is still in its static-protective package, touch it to an unpainted metal
part of the Bull Blade Chassis - Enterprise or any unpainted metal surface on any other
grounded rack component in the rack you are installing the device in for at least 2
seconds. This drains static electricity from the package and from your body.
