System Reliability Guidelines - IBM System x3650 M4 BD Type 5466 Installation And Service Manual

v Have a small flat-blade screwdriver available.
v To view the error LEDs on the system board and internal components, leave the
server connected to power.
v You do not have to turn off the server to install or replace hot-swap power
supplies, hot-swap fans, or hot-plug Universal Serial Bus (USB) devices.
However, you must turn off the server before you perform any steps that
involve removing or installing adapter cables and you must disconnect the
power source from the server before you perform any steps that involve
removing or installing a riser card.
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

The system reliability guidelines to ensure proper system cooling.
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 If the server has redundant power, each of the power-supply bays has a power
supply 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 failed fan within 48 hours.
v You have replaced a hot-swap drive 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 microprocessor to overheat.
