System reliability considerations

To help ensure proper cooling and system reliability, make sure that:
v Each of the module bays on the rear of the BladeCenter unit has either a module
v Each installed power modules must be connected to an ac power source. Do not

Handling static-sensitive devices

Attention:
chassis. 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:
v Limit your movement. Movement can cause static electricity to build up around
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed 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
v Remove the device from its package and install it directly into the BladeCenter
v Take additional care when handling devices during cold weather. Heating reduces
