• Orange on a component or an orange label on or near a component indicates that the component can be

hot-swapped if the server and operating system support hot-swap capability, which means that you can

remove or install the component while the server is still 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.

• 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

Review the system reliability guidelines to ensure proper system cooling and reliability.

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 fan must be replaced within 30 seconds after removal.

• 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.

You might need to keep the power on with the server cover removed to look at system information on the

display panel or to replace hot-swap components. Review these guidelines before doing so.

Attention: The server might stop responding and data loss might occur when internal server components

are exposed to static electricity. To avoid this potential problem, always use an electrostatic-discharge wrist

strap or other grounding systems when working inside the server with the power on.

• Avoid loose-fitting clothing, particularly around your forearms. Button or roll up long sleeves before

working inside the server.

• Prevent your necktie, scarf, badge rope, or long hair from dangling into the server.

• Remove jewelry, such as bracelets, necklaces, rings, cuff links, and wrist watches.
