Safety Notices

Caution: To reduce the risk of electric shock which co uld cause



per s onal injury, follow all safe ty no tices. The symbols shown are used in your documentation and on your equipment to indicate safety hazards.

Warning: Lith ium ba tte ries can be dangerous. Improper ha ndling



of lit h iu m bat t e r ies ma y re su lt in a n exp lo s io n. Dis pose o f lit hium batteries as required by loca l ordinance or as normal waste if no local ordinance exists.



Warning: The detachable power supply cord is intended to serve

as the disconnect device.



Warning: This equipment has two 3-wire, grounded power cords.

To prevent electrical hazards, do not remove or defeat t he ground prong on the power cord. Replace the power cord if it gets damaged. Contact your dealer for an exact replacement.



Warning: The DC push-button on/off switch on the front panel

does not turn off the syste m AC power. Also , +5vdc is present o n the system board whenever the AC power cord is connected between the system and an AC out let. Befor e doing the procedures in this manual, make sure that your system is powered off and unplug the AC power cord from the back of the chassis. Failure to disconnect power before opening your system can result in personal injury and equipment damage.

In the U.S.A. and Canada, each power cord must be a UL-listed detachable power cord (in Canada, CSA-certified), type ST or SJT, 16 AWG, 3-conductor, provided with a molded-on NEMA type 5-15 P plug cap at one end and a molded-on cord connector body at the other end. The cord length must not exceed 9 feet ( 2.7 meter s).

x Using This Guide

Outside the U.S.A. and Canada, the plug must be rated for 250 Vac, 10 amp minimum, and must display an international agency approval marking. The cord must be suitab le for use in the end-user country. Consult your dealer or the local electrical author it ies if you are unsure o f the type of power cord to use in your country. The voltage change occurs via a switch in the power supply.

Warning: Under no circumstances should the user attempt to



disassemble the power supply. The power supply has no userreplaceable parts. Inside the power supply are hazardous voltages that can cause serious personal injury. A defective power supply must be returned to your dealer.

Safety Notices for Users Outside of the U.S.A. and Canada

Overview

The server is a modular, multiprocessing server based on the Int el Pentium® II Xeon chip set. The chip set incor po r ates a modular sca lea ble arc h itect ure that integrates a 64-bit bus interface with three Peripheral Co mponent I nt er co nnect (PCI) buses and an Indust r y Standard Arc h itect ure (ISA) bus. The architecture supports Symmetrical Multiprocessing (SMP) and a variety of operating systems. The chassis and system boards ar e designed to meet the needs of the server marketplace.

The combination of comput ing performance, memory capacity, and integrated I/O provides a high performance environment for many applications including network servers and multi-user systems. The server is designed for use in applications where downtime must be minimized. To this end, the server includes or has the option to include the following.

a metal EMI door; drives can be swapped in or out of the system without

powering it down. T he arr ay of drives allows eas y setup of RAID

applications.

A hot swap-capable backplane is part of each drive cage assembly for

SCSI hard drives. The backplane is designed for Ultra2 wide SCSI-2

devices that use the industry standard 80-pin Single Connector Attach

(SCA) connector. The backplane consists of a row of four drive

Confi gur a tion Cons tr ai nt s

The system has four 5 1/4-inch half-he ig ht ba ys access ib le fro m the front . These bays are convenient for diskette, tape, and CD-ROM drives (removable media). Because of the EMI generated by hard drives, the increased susceptibility to ESD, and cooling requirements, hard drives should not be insta lled in the 5 1/4inch half- he ig ht bays.
