Handling Your System

Follow these guidelines for handling your Xserve RAID system and its components:

mWhen lifting or moving the system, always have two people carry it and place the unit on a sturdy, flat surface.

Important Do not attempt to lift or move the system by yourself. The weight of the unit requires two people to lift and support it.

mWhen connecting or disconnecting a cable, always hold the cable by its connector (the plug, not the cord).

mBefore removing or replacing a RAID controller module, be sure to shut down the controller using the RAID Admin application. Failure to do so could result in data loss.

Certain components—drive modules, power supply, and cooling modules—are designed to be installed or removed while the system is turned on and operating.

mNever force a connector into a port. If the connector and port do not join with reasonable ease, they probably don’t match. Make sure that the connector matches the port and that you have positioned the connector correctly in relation to the port.

mTo remove a fibre channel cable from the RAID controller, push in on the connector slightly, then squeeze the release latch and pull out the connector. If the cable does not pull out easily, use a small flat tool, such as a tiny screwdriver or the cover from the card slot on the host system, to squeeze the release latch.

mDon’t spill food or liquid on the system or other components. If you do, turn your system off immediately and unplug it before cleaning up the spill. Depending on what you spilled and how much of it got into your equipment, you may have to arrange for an Apple- authorized service provider to inspect or repair the system.

mProtect the system and its components from direct sunlight and rain or other moisture.

mKeep all ventilation openings clear and unobstructed. Without proper air circulation, the unit’s temperature can rise high enough to cause the system to shut down.

Power Supply

The power supplies in your system are high-voltage components and should not be opened for any reason, even when the system is off. If a power supply needs service, contact your Apple-authorized dealer or service provider.

Cleaning Your Equipment

Follow these general rules when cleaning the outside of your system:
