Caution: 

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 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 are intended to serve as the disconnect devices. Contact

your dealer for an exact replacement.

The DC push-button on/off switch on the front panel does not turn off

the system AC power. Also, +5vdc is present on the system board

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 equipment damage.

Under no circumstances should the user attempt to disassemble the

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.

Immediately after powering off the system, components such as CPU

processor heatsinks and hard disk drives may be very hot. Wait for the

system 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.
