Introduction 13

Installing the switch

When populating your IBM Flex System chassis, refer to the documentation that comes with your

IBM Flex System 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 IBM 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 Fibre Channel SAN.

The chassis supports a maximum of four IBM Flex System FC5022 16Gb SAN Scalable Switches

and a maximum of 14 1-bay compute nodes.

See the documentation that comes with your IBM Flex System chassis for information about switch

bay locations and the components that can be installed in them that are specific to your chassis

type.

NOTES:

• The compute nodes or chassis that are described or shown in this document might be different

from your compute node or chassis. For additional information, see the documentation that

comes with your compute node or chassis.

• When the switch is installed in the chassis, the internal ports can operate at 8 or 16 Gbps and

external FC ports can operate at 4, 8, or 16 Gbps (auto-negotiated).

• Configuration requirements for the switch and chassis might vary. For the most up-to-date

product documentation for all of your IBM Flex System products, go to the IBM Flex System

Information Center at http://publib.boulder.ibm.com/infocenter/flexsys/information/index.jsp.
