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 available.
v You do not have to turn off the server to install or replace hot-swap power
supplies 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.
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 and 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 have to access the inside of the server, you might find it easier to lay
the server on its side.
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://

System reliability guidelines
To help ensure proper system cooling and system reliability, make sure that the
following requirements are met:
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 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.
When you install the server in a rack, make sure that space is available around
the server to enable the server cooling system to work properly. See the
documentation that comes with the rack for additional information.
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.
Working inside the server with the power on
Attention: Static electricity that is released to internal server components when
the server is powered-on might cause the server to halt, which might result in the
loss of data. To avoid this potential problem, always use an electrostatic-discharge
wrist strap or other grounding system when you work inside the server with the
power on.
