Safety Notices



Caution: To reduce the risk of electric shock which could cause personal injury, follow

all safety notices. T he symbols shown are used in your documentat ion and on your equipment to indicate safety hazards.



Warning: Lithium ba tte ries can be dangerous. Improper ha ndling o f lithium batteries

may resu lt in an e xp losion. Dispose o f lithium b atteries a s r eq uired b y local or di n an ce o r as normal waste if no local ordinance e x ist s.

Warning: The detachable power supply cords are intended to serve as the disconnect



devices.



Warning: This equipment has a 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. Contact your dealer for an exact replacement .



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

system AC power. Also, +5vdc is present o n t he syste m board whenever the AC power cords are connected bet ween t he syst em 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. Fai lure to disconnect power before o p ening your system can result in personal injury and equipment damage.

In the U.S.A. and Canada, the power cord must be a UL-listed detachable power cor d (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 meters).

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 cor d must be suita b le for use in the end-user country. Consult your dea ler or the local electrical authorities if you are unsure of 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 po wer

supply. The power supply has no user-replaceable parts. Inside the power supply are hazardous voltages that can cause serious persona l injury. A defective power supply must be returned to your dealer.

Overview

This server is a modular, multiprocessing server based on t he Intel Pentium® II and Pentium® III chip sets. The combination of compute performance, memory capacity, and integrated I/O provides a high performance enviro nme nt for many server market applications.

This s erve r is a ls o conveniently housed in a tow er-bas ed, as shown below.

Tower-Based System Front View

This s erve r system is d esigned for minimu m downtime. To this end , the s e rver includes or has the options to include the following:



Optional power system redundancy; in a system configured with two power supplies,

the system will continue to operat e with a single power supp ly failure.



Self-contained power supply units that can be easily installed or removed from the

back of the chassis.



SCSI drive bays access ib le from the front of the chassis.



Hot-swap SCSI disk drive backplane; a failed drive can be removed and a new drive

installed without system power being turned off, if an optional Redundant Array of Independ ent Disks ( RAID ) co ntro lle r is in s talled.



High degree of SCSI disk fault tolerance and advanced disk arra y management

features through the use of RAID technolog y, if an optional RAID co nt ro ller is installed.



Chassis that supports up to two power supplies. The second power supply can be

added to provide redundant power.

SAF-TE Board

The system has a SAF-TE ( S CSI Accessed Fault T olerant Enclosure) boar d that provides an inter face for the d isk subs ystem to automatically integrat e with per ipheral packaging that supports status signals, hot swapping drives, and enclosure monitoring.

The transport mechanism for the st andardized alert detection and status reporting is the SCSI bus. Disk drives, power supplies, cooling fans, and temperature are continually monitored and the conditions then reported over the SCSI bus to the system. When used with RAID management software the user can be alerted of impending or imminent disk conditions requiring attent ion. This allows the user to react to conditions that could normally go unnoticed until data loss.

1-8 System Overview

Processors

Depending on system configuration, each system may include one or two processors. Each processo r is packaged in either a S ingle Edge Contact Cartridge (SECC) or Single Edge Contact Cartr idge 2 (SECC2) package. The cartr idge includes t he processor core with an integrated 16 KB primary (L1) cache; the secondar y (L2) cache; a t her mal plate; and a back cover. The processor implements the MMX™ technology and the processo r ’s nu meric co pro cessor significantly increases the speed of floating-point operations.

The processo r exte r nal interface is MP (Multi-Pro cessor) ready and operates at a maximum of 100 MHz. The processor contains a local APIC (Advanced Programmable Interrupt Controller) section for interrupt handling in MP and UP (Uni-Processor) environments.

The second-level cac he is located on the substrate o f the processor cart r idge. The cache includes burst pipelined synchronous static RAM (BSRAM). The L2 cache is offered in 512 KB configurations only, with error correcting code (ECC) that operates at half the core clock rate.

System Memory

The system board contains four 168-pin DIMM sockets. Memory is partitioned as four banks of SDRAM DIMMs, each pro viding 72 bits of noninterleaved memory (64-bit main memory p lus ECC ). Your s ystem may include from 32 MB t o 1 GB of memory, using up to four DIMMs.

System memory begins at address 0 and is continuous (flat addressing) up to the maxi mu m amo u nt of DRAM ins t a lle d ( exc ep tion: syste m memo r y is no nc o ntigu o u s in the ranges defined as memory holes using configuration registers). The system supports both base (co nvention al) a nd extended me mory.

Memory should be added in order from slot 1 to slot 4.

Note:

Use DIMMS currently available from the Approved

Note:

Vendors List (AVL) only. Contact your NEC sales representative or dealer for the curr ent AV L of mem ory modules (DI M M s) available for your server.
