System reliability considerations
To help ensure proper cooling and system reliability, make sure that:
v Each of the I/O-module bays on the rear of the BladeCenter unit has either a
module or a filler module installed.
v A removed hot-swap module or blade server is replaced with another
module or filler module within 1 minute of removal.
Handling static-sensitive devices
Attention: Static electricity can damage 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 electrostatic discharge, observe the following
precautions:
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 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 any
unpainted metal surface of the BladeCenter unit or any unpainted metal
surface on any other grounded rack component 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
BladeCenter unit 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 BladeCenter unit or on a metal surface.
v Take additional care when handling devices during cold weather. Heating
reduces indoor humidity and increases static electricity.
Installing a Gigabit Ethernet switch module
To install a Gigabit Ethernet switch module, complete the following steps:
1. Read the safety information beginning on page v and "Installation
guidelines" on page 13.
2. Remove the acoustic attenuation module, if one is installed, from the rear
of the BladeCenter unit. For more information, see the documentation that
came with the BladeCenter unit.
3. Select an I/O-module bay in which to install the Gigabit Ethernet switch
module.
