xSeries 440:Option Installation Guide
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 package until you are
ready to install them.
To reduce the possibility of electrostatic discharge, observe the following precautions:
• Limit your movement. Movement can cause static electricity to build up around
you.
• Handle the device carefully, holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed printed circuitry.
• Do not leave the device where others can handle and possibly damage the device.
• While the device is still in its anti-static 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.)
• Remove the device from its package and install it directly into your system unit
without setting it down. If it is necessary to set the device down, place it in its
static-protective package. Do not place the device on your system unit cover or on
a metal table.
• Take additional care when handling devices during cold weather because heating
reduces indoor humidity and increases static electricity.
System reliability considerations
To help ensure proper cooling and system reliability, make sure that:
• Each of the drive bays has either a drive or a filler panel installed.
• There is space around the server to allow the cooling system to work properly.
• Cables for optional adapters are routed according to the instructions that are pro-
vided with the adapters.
• All microprocessors are the same size and clock speed.
• When two SMP Expansion modules are installed, they are connected together
through the SMP Expansion Ports.
• An SMP baffle is installed on top of the lower SMP Expansion module when only
one module is installed.
• For proper cooling, do not leave the cover open for more than 30 minutes.
• A failed fan is replaced within 48 hours.
• The top cover is closed during normal operation.
• Do not remove a defective power supply until a replacement is available.
