removing or installing a specific hot-swap component for any additionalprocedures that you might have to perform before you remove or install thecomponent.v Blue on a component indicates touch points, where you can grip the componentto remove it from or install it in the BladeCenter S chassis, open or close a latch,and so on.System reliability guidelinesTo help ensure proper system cooling and system reliability, make sure thefollowing requirements are met.v Each of the module bays on the front and rear of the BladeCenter S chassis haseither a module or a module bay filler installed in it.v Each of the blade bays on the front of the BladeCenter S chassis has either ablade server or a blade bay filler installed in it.v Each of the disk storage module bays has a disk storage module or disk storagemodule filler installed in it. If a disk storage module is installed, each of thedrive bays has a hard disk drive or a hard disk drive bay filler installed in it.v Each of the drive bays in a blade server storage expansion option has either ahot-swap drive or a filler panel installed.v You have followed the cabling instructions that come with optional adapters.v Cables for the optional modules are routed correctly.v A failed fan module is replaced as soon as possible.Handling static-sensitive devicesMake sure that you read these guidelines before handing static-sensitive devices.About this taskAttention: Static electricity can damage the BladeCenter S chassis and otherelectronic devices. To avoid damage, keep static-sensitive devices in theirstatic-protective packages until you are ready to install them.To reduce the possibility of electrostatic discharge, observe the followingprecautions:v Limit your movement. Movement can cause static electricity to build up aroundyou.v The use of a grounding system is recommended. For example, wear anelectrostatic-discharge wrist strap, if one is available.v Handle the device carefully, holding it by its edges or its frame.v Do not touch solder joints, pins, or exposed circuitry.v Do not leave the device where others can handle and damage it.v While the device is still in its static-protective package, touch it to an unpaintedmetal part of the BladeCenter S chassis or rack for at least 2 seconds. This drainsstatic electricity from the package and from your body.v Remove the device from its package and install it immediately without settingdown the device. If it is necessary to set down the device, put it back into itsstatic-protective package.v Take additional care when you handle devices during cold weather. Heatingreduces indoor humidity and increases static electricity.26 BladeCenter S Type 7779/8886: Installation and User's Guide
