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

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 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 turning 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 drive within 2 minutes of removal.

Handling static-sensitive devices

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 The use of a grounding system is recommended. For example, wear an
electrostatic-discharge wrist strap, if one is available.
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.
v While the device is still in its static-protective package, touch it to an unpainted
metal surface on the outside of the server for at least 2 seconds. This drains
static electricity from the package and from your body.
v Remove the device from its package and install it directly into the server without
setting down the device. If it is necessary to set down the device, put it back into
its static-protective package. Do not place the device on the server cover or on a
metal surface.
v Take additional care when you handle devices during cold weather. Heating

reduces indoor humidity and increases static electricity.
