Safety Instructions
CAUTION: Safety Instructions
Use the following safety guidelines to help ensure your own personal safety and to help protect your computer and working environment from potential damage.
General
•Do not attempt to service the computer yourself unless you are a trained service technician. Always follow installation instructions closely.
•To help prevent electric shock, plug the computer and device power cables into properly grounded electrical outlets. These cables are equipped with 3-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a 3-wire cable with properly grounded plugs.
•To help avoid the potential hazard of electric shock, do not use your computer during an electrical storm.
•To help avoid the potential hazard of electric shock, do not connect or disconnect any cables or perform maintenance or reconfiguration of this product during an electrical storm.
•If your computer includes a modem, the cable used with the modem should be manufactured with a minimum wire size of 26 American wire gauge (AWG) and an FCC-compliant RJ-11 modular plug.
•Before you clean your computer, disconnect the computer from the electrical outlet. Clean your computer with a soft cloth dampened with water. Do not use liquid or aerosol cleaners, which may contain flammable substances.
•To help avoid possible damage to the system board, wait 5 seconds after turning off the computer before disconnecting a device from the computer.
•To avoid shorting out your computer when disconnecting a network cable, first unplug the cable from the network adapter on the back of your computer, and then from the network jack. When reconnecting a network cable to your computer, first plug the cable into the network jack, and then into the network adapter.

•To help protect your computer from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).
•Ensure that nothing rests on your computer’s cables and that the cables are not located where they can be stepped on or tripped over.
•Do not push any objects into the openings of your computer. Doing so can cause fire or electric shock by shorting out interior components.
•Keep your computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose papers underneath your computer; do not place your computer in a closed-in wall unit or on a bed, sofa, or rug.
When Using Your Computer
As you use your computer, observe the following safe-handling guidelines.
CAUTION: Do not operate your computer with any cover(s) (including computer covers, bezels, filler brackets, front-panel inserts, and so on) removed.
Your computer is equipped with one of the following:
•A fixed-voltage power supply — Computers with a fixed-voltage power supply do not have a voltage selection switch on the back panel and operate at only one voltage (see the regulatory label on the outside of the computer for its operating voltage).
•An auto-sensing voltage circuit — Computers with an auto-sensing voltage circuit do not have a voltage selection switch on the back panel and automatically detect the correct operating voltage.
•A manual voltage selection switch — Computers with a voltage selection switch on the back panel must be manually set to operate at the correct operating voltage.
To help avoid damaging a computer with a manual voltage selection switch, ensure that the voltage selection switch is set to match the AC power available at your location:
•115 V/60 Hz in most of North and South America and some Far Eastern countries such as South Korea and Taiwan
2
•100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
•230 V/50 Hz in some regions in the Caribbean and South America and most of Europe, the Middle East, and the Far East
Also, ensure that your monitor and attached devices are electrically rated to operate with the AC power available in your location.
•Before working inside the computer, unplug the computer to help prevent electric shock or system board damage. Certain system board components continue to receive power any time the computer is connected to AC power.
When Working Inside Your Computer
Before you open the computer cover, perform the following steps in the sequence indicated.
CAUTION: Do not attempt to service the computer yourself, except as explained in your online Dell™ documentation or in instructions otherwise provided to you by Dell. Always follow installation and service instructions closely.
NOTICE: To help avoid possible damage to the system board, wait 5 seconds after turning off the computer before removing a component from the system board or disconnecting a device from the computer.
1Perform an orderly computer shutdown using the operating system menu.
2Turn off your computer and any devices connected to the computer.
3Ground yourself by touching an unpainted metal surface on the chassis, such as the metal around the card-slot openings at the back of the computer, before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity that might harm internal components.
4Disconnect your computer and devices, including the monitor, from their electrical outlets. Also, disconnect any telephone or telecommunication lines from the computer.
Doing so reduces the potential for personal injury or shock. In addition, take note of these safety guidelines when appropriate:
NOTE: The voltage selection switch must be set to the 115-V position even though the AC power available in Japan is 100 V.

•When you disconnect a cable, pull on its connector or on its strainrelief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.
•Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a microprocessor chip by its edges, not by its pins.
CAUTION: There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. Do not dispose of the battery along with household waste. Contact your local waste disposal agency for the address of the nearest battery deposit site.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer’s electronic components, such as the microprocessor. You can do so by touching an unpainted metal surface on the computer chassis.
As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have accumulated.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
•Do not remove components from their antistatic packing material until you are ready to install the component in your computer. Just before unwrapping the antistatic packaging, discharge static electricity from your body.
•When transporting an electrostatic sensitive component, first place it in an antistatic container or packaging.
•Handle all electrostatic sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.

Ergonomic Computing Habits
CAUTION: Improper or prolonged keyboard use may result in injury.
CAUTION: Viewing the monitor screen for extended periods of time may result in eye strain.
Battery Disposal
Do not dispose of the battery along with household waste. Contact your local waste disposal agency for the address of the nearest battery deposit site.

NOTE: The information in this document applies to PERC 3/QC, PERC 3/DC, PERC 3/DCL and PERC 3/SC.
PERC 3 Overview
The Dell™ PowerEdge™ Expandable RAID Controller 3 (PERC 3) PCI card is a high-performance, intelligent peripheral component interconnect (PCI)-to-SCSI host adapter with RAID control capabilities. PERC 3 provides system availability, high performance, and fault-tolerant disk subsystem management. PERC 3 is an ideal RAID solution for the internal storage of Dell’s workgroup, departmental, and enterprise systems. PERC 3 offers a cost-effective way to implement RAID in a server.
The PERC 3/QC low voltage differential (LVD) PCI RAID card provides four SCSI channels. The PERC 3/DC and PERC 3/DCL LVD PCI RAID card provides two SCSI channels. The PERC 3/SC LVD PCI RAID card provides one SCSI channel.
With LVD, you can use cables up to 25 meters long. Throughput on each SCSI channel can be as high as 160 MB/s. PERC 3 supports both an LVD SCSI bus and a single-ended SCSI bus.
PERC 3 64-bit LVD is a high-performance, intelligent PCI-to-SCSI host adapter with RAID control capabilities. PERC 3 64-bit LVD requires no special motherboard PCI expansion slot.
PERC 3 Features
The PERC 3 features include:
•Wide Ultra3 LVD SCSI performance of up to 160 MB/s
•PERC 3/QC and PERC 3/DC support 128 MB of synchronous dynamic random access memory (SDRAM.)
•The PERC 3/DCL supports 64 MB of SDRAM.
•The PERC 3/SC supports 32 MB of SDRAM.
•64-bit PCI host interface (only on PERC 3/QC and PERC 3/DC)
•The PERC 3/QC, PERC 3/DC and PERC 3/DCL have an on-board i960RN processor to improve controller performance and offload host Central Processing Unit (CPU.)
•The PERC 3/SC has a on-board i960RM processor to improve controller performance and offload host CPU.
24 Over view
•Two internal and four external connectors for the PERC 3/QC, two internal and two external connectors for the PERC 3/DC and PERC 3/DCL, and one internal and one external connector for the PERC 3/SC
•RAID levels 0 (striping), 1 (mirroring), 5 (distributed parity), 10 (combination of striping and mirroring), and 50 (combination of striping and distributed parity)
•Advanced array configuration and management utilities
•Battery backup for up to 72 hours for the PERC 3/QC and PERC 3/DC
•Up to 12 SCSI drives per channel using the Dell PowerVault 21xS storage system or 14 SCSI drives using the Dell PowerVault 22xS
SCSI Channels
The PERC 3/QC controller card includes four SCSI channels. There are two QLogic®12160 chips; each chip controls two SCSI channels.
The PERC 3/DC and PERC 3/DCL controller cards include two SCSI channels. There is one QLogic 12160 chip, which controls two SCSI channels.
The PERC 3/SC controller card has one SCSI channel. There is one QLogic 10160 chip.
Non-volatile Random Access Memory (NVRAM) and Flash Readonly Memory (ROM)
A 32 KB x 8 NVRAM stores RAID system configuration information. The PERC 3 firmware is stored in flash ROM for easy upgrade.
