v
The ventilation areas on the sides of the compute node are not blocked.
v You have followed the reliability guidelines in the documentation that comes with
the IBM Flex System chassis.
Cable requirements for the switch are described in the IBM Configuration and
Options Guide at http://www.ibm.com/servers/eserver/xseries/cog/.
Handling static-sensitive devices
Attention: Static electricity can damage the IBM Flex System chassis 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 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 an unpainted
metal surface of the IBM Flex System chassis or an unpainted metal surface on
any other grounded rack component in the rack that you are installing the device
in 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 IBM Flex
System chassis without setting down the device. If it is necessary to set down
the device, put it back into its static-protective package. Do not place the device
on the IBM Flex System chassis or on a metal surface.
v
Take additional care when you handle devices during cold weather. Heating
reduces indoor humidity and increases static electricity.
v
Some types of IBM Flex System chassis come with electrostatic discharge (ESD)
connectors. If your unit is equipped with an ESD connector, see the
documentation that comes with the IBM Flex System chassis for using the ESD
connector.
Installing the switch
Note: The following illustration shows how to install a switch in an IBM Flex
System chassis. The appearance of your IBM Flex System chassis might be
different; see the documentation for your IBM Flex System chassis for
additional information.
Use the following instructions to install a switch in the IBM Flex System chassis.
You can install a switch while the IBM Flex System chassis is powered on. For
redundancy support, you must install I/O modules of the same type in I/O bays 1
and 2, and I/O modules of the same type in bays 3 and 4 of the chassis.
To install a switch, complete the following steps.
