Installing the Switch
This chapter provides information and instructions for installing, configuring, and cabling the
switch. See the IBM Flex System Installation and Service Guide that comes with your IBM Flex
System chassis to install the switch in the chassis; then return to this User’s Guide for the
information and instructions needed to complete the installation.
Installation guidelines
Before you install the IBM Flex System EN4023 10Gb Scalable Switch in the IBM Flex System
chassis, pay attention to the following guidelines:
•Read the safety information that includes “Safety statements” on page viii, “Handling
static-sensitive devices” on page 10, and the safety statements in the chassis documentation.
•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 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 chassis indicates that the component can be hot-swapped, which means that if the
chassis and operating system support hot-swap capability, you can remove or install the
component while the 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 chassis to install or replace any of the hot-swap modules on the
front or rear of the chassis.
•When you install a switch in the chassis, you must also install a compatible network adapter in
the compute node to support the switch.
•When you are finished working on the compute node or chassis, reinstall all safety shields,
guards, labels, and ground wires.
For a list of supported optional devices for the chassis and other IBM products, see
http://www.ibm.com/servers/eserver/serverproven/compat/us/.
System reliability guidelines
To help ensure proper cooling, performance, and system reliability, make sure the following
requirements are met:
•Each of the switch bays at the rear of the chassis contains either a switch or a filler blade.
•A removed hot-swap module is replaced with an identical module or filler module within
60 seconds of removal.

10 IBM Flex System EN4023 10Gb Scalable Switch User’s Guide
Installation guidelines
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 IBM 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.
