IBM System x3550 M3 Type 4254 Problem Determination And Service Guide

v If you must start the server while the cover is removed, make sure that no one is
near the server and that no other objects have been left inside the server.
v Do not attempt to lift an object that you think is too heavy for you. If you have to
lift a heavy object, observe the following precautions:
– Make sure that you stand safely without slipping.
– Distribute the weight of the object equally between your feet.
– Use a slow lifting force. Never move suddenly or twist when you lift a heavy
object.
– To avoid straining the muscles in your back, lift by standing or by pushing up
with your leg muscles
v Make sure that you have an adequate number of properly grounded electrical
outlets for the server, monitor, and other devices.
v Back up all important data before you make changes to disk drives.
v Have a small flat-blade screwdriver, a small Phillips screwdriver, and a T8 torx
screwdriver available.
v You do not have to turn off the server to install or replace hot-swap power
supplies, hot-swap fans, hot-swap drives, 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 before you perform any steps that involve removing or installing riser
cards.
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.
v For a list of supported optional devices for the server, see http://www.ibm.com/
servers/eserver/serverproven/compat/us/.
System reliability guidelines
To help ensure proper 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 There is adequate space around the server to allow the server cooling system to
work properly. Leave approximately 50 mm (2 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.
Operating the server for extended periods of time (more than 30 minutes) with
the server cover removed might damage server components.
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 fan within 30 seconds of removal.
