10 Protecting Against Electrostatic DischargeIn addition, take note of these safety guidelines when appropriate:• When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have aconnector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before disconnecting thecable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connecta cable, make sure 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 byits metal mounting bracket. Hold a component such as a microprocessor chip by its edges, not by its pins.Protecting Against Electrostatic DischargeElectrostatic discharge (ESD) events can harm electronic components inside your computer. Under certain conditions, ESD maybuild up on your body or an object, such as a peripheral, and then discharge into another object, such as your computer. To preventESD damage, you should discharge static electricity from your body before you interact with any of your computer’s internal electroniccomponents, such as a memory module. You can protect against ESD by touching a metal grounded object (such as an unpaintedmetal surface on your computer’s I/O panel) before you interact with anything electronic. When connecting a peripheral (includinghandheld digital assistants) to your computer, you should always ground both yourself and the peripheral before connecting it tothe computer. In addition, as you work inside the computer, periodically touch an I/O connector to remove any static charge yourbody may have accumulated.You can also take the following steps to prevent damage from electrostatic discharge:• When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistaticpacking material until you are ready to install the component. Just before unwrapping the antistatic package, be sure todischarge static electricity from your body.• When transporting a 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 work bench pads.SAFETY: Battery DisposalYour system may use a nickel-metal hydride (NiMH), lithium coin-cell, and/or a lithium-ion battery. The NiMH,lithium coin-cell, and lithium-ion batteries are long-life batteries, and it is very possible that you will never need toreplace them. However, should you need to replace them, refer to the instructions included in the section "RAIDConfiguration and Management" on page 49.Do not dispose of the battery along with household waste. Contact your local waste disposal agency for the address ofthe nearest battery deposit site.NOTE: Your system may also include circuit cards or other components that contain batteries. These batteries must alsobe disposed of in a battery deposit site. For information about such batteries, refer to the documentation for the specific cardor component.Taiwan Battery Recycling MarkDell_PERC5_UG.book Page 10 Tuesday, February 13, 2007 6:02 PM
