Installation guidelines
Before you install the switch in the IBM Flex System chassis, consider the following
information:
•
Read the safety information that begins on page v, “Handling static-sensitive
devices” on page 19, and the safety statements in the IBM Flex System chassis
documentation. This information will help you work safely.
• Observe good housekeeping in the area where you are working. Place removed
covers and other parts in a safe place.
•
Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the compute node or IBM Flex System chassis,
open or close a latch, and so on.
• Orange on a component or an orange label on or near a component on the
switch, compute node, or IBM Flex System chassis indicates that the component
can be hot-swapped, which means that if the IBM Flex System chassis and
operating system support hot-swap capability, you can remove or install the
component while the IBM Flex System chassis is running. (Orange can also
indicate touch points on hot-swap components.) See the instructions for
removing or installing a specific hot-swap component for any additional
procedures that you might have to perform before you remove or install the
component.
•
You do not have to turn off the IBM Flex System chassis to install or replace any
of the hot-swap modules on the rear of the IBM Flex System chassis.
• When you install a switch in the IBM Flex System chassis, you must also install a
compatible I/O network adapter in the compute node to support the switch.
•
When you are finished working on the compute node or IBM Flex System
chassis, reinstall all safety shields, guards, labels, and ground wires.
• For a list of supported optional devices for the IBM Flex System chassis and other
IBM products, see

System reliability guidelines
To help ensure proper cooling, performance, and system reliability, make sure that
the following requirements are met:
•
Each of the switch bays on the rear of the IBM Flex System chassis contains either
a switch or a filler switch.
• A removed hot-swap switch is replaced with an identical switch or filler switch
within 1 minute of removal.
•
A removed hot-swap compute node is replaced with another compute node or
filler blade within 1 minute of removal.
• The ventilation areas on the sides of the compute node are not blocked.
•
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/. See the
documentation that comes with the compute node for cable-routing information.
