IBM 8677 manual System reliability considerations, Handling static-sensitive devices

some restrictions, hot-swap blade servers while the BladeCenter unit is running. For complete details about installing or removing a hot-swap component, see the detailed information in this chapter.

vThe blue color on components and labels identifies touch points where you can grip a component, move a latch, and so on.

vYou do not need to disconnect the BladeCenter unit from power to install or replace any of the hot-swap modules on the rear of the BladeCenter unit. You need to shut down the operating system and turn off a hot-swap blade server on the front of the BladeCenter unit before removing the blade server, but you do not need to shut down the BladeCenter unit itself.

vFor a list of supported options for your BladeCenter unit, go to http://www.ibm.com/pc/compat/ on the World Wide Web.

System reliability considerations

To help ensure proper cooling and system reliability, make sure that:

vEach of the module bays on the rear of the BladeCenter unit has either a module or filler module installed.

vEach of the blade bays on the front of the BladeCenter unit has either a blade server or filler blade installed.

vEach of the drive bays in a blade server storage expansion option has either a hot-swap drive or a filler panel installed.

vA removed hot-swap module, blade server, or drive is replaced within 1 minute of removal.

vCables for the option modules are routed according to the illustrations and instructions in this document.

vA failed blower is replaced as soon as possible, to restore cooling redundancy.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and your system. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following precautions:

vLimit your movement. Movement can cause static electricity to build up around you.

vHandle the device carefully, holding it by its edges or its frame.

vDo not touch solder joints, pins, or exposed printed circuitry.

vDo not leave the device where others can handle and damage it.

vWhile the device is still in its static-protective package, touch it to an unpainted metal part of the system unit for at least 2 seconds. This drains static electricity from the package and from your body.

vRemove the device from its package and install it directly into the system unit without setting the device down. If it is necessary to set down the device, place it back into its static-protective package. Do not place the device on your system unit or on a metal surface.

vTake additional care when handling devices during cold weather. Heating reduces indoor humidity and increases static electricity.
