Installing the switch
2
•
A removed hot-swap compute node should be replaced with another compute node or filler
blade within 60 seconds of removal.
•
The ventilation areas on the sides of the compute node power modules and blowers are not
blocked.
•
You have followed the reliability guidelines in the documentation that comes with the chassis.
Cable requirements for the switch are described in the Lenovo System x Configuration and Options
Guide at http://www.ibm.com/servers/eserver/xseries/cog/ . See the documentation that comes
with the compute node for cable-routing information.
Handling static-sensitive devices
ATTENTION
Static electricity can damage the 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:
•
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 damage it.
•
While the device is still in its static-protective package, touch it to an unpainted metal surface
of the chassis or an unpainted metal surface on any other grounded rack component in the
rack in which you are installing the device for at least two seconds. This drains static electricity
from the package and from your body.
•
Remove the device from its package and install it directly into the 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 chassis or on a metal surface.
•
Take additional care when you handle devices during cold weather. Heating reduces indoor
humidity and increases static electricity.
•
Some types of chassis come with electrostatic discharge (ESD) connectors. If the chassis is
equipped with an ESD connector, see the documentation that comes with the chassis for using
the ESD connector.
Installing the switch
When populating your Lenovo Flex System chassis, refer to the documentation that comes with
your chassis to determine the relevant order for populating the chassis I/O module bays.
A compatible network adapter must be installed in each compute node with which you want to
communicate. To enable the switch to communicate with a compute node, at least one switch must
be installed in the chassis. If only one switch is being used to populate the chassis, ensure that you
insert the switch in the recommended chassis I/O module bay. Refer to the support documentation
that comes with your Lenovo Flex System chassis and network adapter for more information.
Installing a second switch enables a redundant path and a separate connection from the compute
node to the external Ethernet switch.
