!WARNING

Lithium batteries can be dangerous. Improper handling of lithium batteries may result in an explosion. Dispose of lithium batteries as required by local ordinance. Replace only with the same or equivalent type battery.

The CD-ROM drive uses a laser beam. Do not look or insert a mirror inside while the system is on. A laser beam is invisible; if your eyes get exposed to it, there is a risk of losing your eyesight.

This equipment uses 3-wire, grounded power cords. To prevent electrical hazards, do not remove or defeat the ground prong on the power cords. Replace a power cord if it gets damaged. The detachable power supply cords are intended to serve as the disconnect devices. Contact your dealer for an exact replacement.

The DC push-button on/off switch does not turn off the system AC power. Also, +5vdc is present within the system whenever the AC power cords are connected between the system and an AC outlet. Before doing the procedures in this manual, make sure that your system is powered off and unplug the AC power cords from the back of the chassis. Failure to disconnect power before opening your system can result in personal injury and/or equipment damage.

Under no circumstances should you attempt to disassemble a power supply. The power supply has no user-replaceable parts. Inside the power supply are hazardous voltages that can cause serious personal injury. A defective power supply must be returned to your dealer.

Never connect the ground wire to a gas pipe. There is a risk of a gas explosion.

The equipment weighs around 60 to 70 kg (depending on its hardware configuration). If you carry it alone, injuries may result. It takes at least four people to carry it; hold the equipment firmly by its bottom. Do not hold the front bezel, or it may become detached, causing an injury.

Immediately after powering off the system, components such as CPU processor heat sinks and hard disk drives may be very hot. Wait for the server to cool down completely before adding/removing components.

Do not attempt to remove a device while it is in operation. Device malfunction or personal injury may result.

Be careful not to get your fingers or hair caught in cooling fans located in the back of a running server.

!Be sure to power off the equipment and unplug its power cords from the wall outlet before installation/relocation. All voltage is removed only when the power cords are unplugged.

!Turn off your cellular phone or pager when you use the equipment. Their radio waves may cause the equipment to malfunction.
