• The Red strip on the drives, adjacent to the release latch, indicates that the drive can be hot-swapped if

the server and operating system support hot-swap capability. This means that you can remove or install
the drive while the server is still running.

Note:

See the system specific instructions for removing or installing a hot-swap drive for any additional

procedures that you might need to perform before you remove or install the drive.

• After finishing working on the server, make sure you reinstall all safety shields, guards, labels, and ground

wires.

System reliability guidelines

The system reliability guidelines to ensure proper system cooling.

Make sure the following requirements are met:

• When the server comes with redundant power, a power supply must be installed in each power-supply

bay.

• Adequate space around the server must be spared to allow 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 any
object in front of the fans.

• For proper cooling and airflow, refit the server cover before you turn the power on. Do not operate the

server for more than 30 minutes with the server cover removed, for it might damage server components.

•  Cabling instructions that come with optional components must be followed.
•  A failed fan must be replaced within 48 hours since malfunction.
•  A removed hot-swap drive must be replaced within two minutes after removal.
•  A removed hot-swap power supply must be replaced within two minutes after removal.
•  Every air baffle that comes with the server must be installed when the server starts (some servers might

come with more than one air baffle). Operating the server with a missing air baffle might damage the
processor.

• All processor sockets must contain either a socket cover or a processor with heat sink.
• When more than one processor is installed, fan population rules for each server must be strictly followed.

Handling static-sensitive devices

Follow this procedure to handle static-sensitive devices.

Attention:

Prevent exposure to static electricity, which might lead to system halt and loss of data, by

keeping static-sensitive components in their static-protective packages until installation, and handling these
devices with an electrostatic-discharge wrist strap or other grounding system.

• Limit your movement to prevent building up static electricity around you.
• Take additional care when handling devices during cold weather, for heating would reduce indoor

humidity and increase static electricity.

• Always use an electrostatic-discharge wrist strap or other grounding system.
• 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 two seconds. This drains static electricity from the package and from your
body.

• Remove the device from the package and install it directly into the server without putting it down. If it is

necessary to put the device down, put it back into the static-protective package. Never place the device
on the server or on any metal surface.

• When handling a device, carefully hold it by the edges or the frame.
