System reliability guidelines To help ensure proper cooling and system reliability, observe the following requirements are met: v Each microprocessor socket always contains either a microprocessor dust cover and heat sink filler or a microprocessor and heat sink. If the blade server has only one microprocessor, it must be installed in microprocessor socket 1. v You do not operate the BladeCenter unit without a blade server, expansion unit, or filler installed in each blade bay. See the documentation for your BladeCenter unit for additional information. Also, make sure that the ventilation holes on the blade server are not blocked. v The blade server battery must be operational. If the battery becomes defective, replace it immediately. For instructions, see the Problem Determination and Service Guide. Handling static-sensitive devices Attention: Static electricity can damage the blade server and other electronic devices. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them. To reduce the possibility of damage from electrostatic discharge, observe the following precautions: v When you work on a BladeCenter T unit, use an electrostatic discharge (ESD) wrist strap, especially when you handle modules, optional devices, or blade servers. To work correctly, the wrist strap must have a good contact at both ends (touching your skin at one end and firmly connected to the ESD connector on the front or back of the BladeCenter T unit). v Limit your movement. Movement can cause static electricity to build up around you. 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 unpainted metal part of the BladeCenter unit or any unpainted metal surface on any other grounded rack component in the rack in which you are installing the device for at least 2 seconds. This drains static electricity from the package and from your body. v Remove the device from its package and install it directly into the blade server without setting it down. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on the blade server cover or on a metal surface. v Take additional care when you handle devices during cold weather. Heating reduces indoor humidity and increases static electricity. 18 BladeCenter LS21 Type 7971 and LS41 Type 7972: Installation and User's Guide
