Chapter 2. Installing and replacing a switch module
This chapter provides instructions for installing a switch module in the BladeCenter
unit and for removing a switch module from the BladeCenter unit.
As of the date of this document, the BladeCenter unit supports a maximum of four
switch modules. Installing a second switch module enables a redundant path and a
separate connection from the blade server to the external Ethernet network.
Attention: If you install the switch module into a BladeCenter unit I/O bay other
than I/O-module bay 1 or I/O-module bay 2 (or I/O-module bay 1 when you are
installing the switch module in a BladeCenter S unit), a compatible expansion card
must be installed into each blade server, blade workstation, or other blade device
that you want to connect to the switch module. The expansion card provides the
connection between the blade device and the I/O bay into which you install the
switch module.
For more information about the I/O bays that are available on your BladeCenter
unit, or for more information about the expansion card types that can be installed in
your blade server, see the documents that come with the device. For information
about the compatibility of your BladeCenter unit, blade servers, and expansion
cards, see http://www.ibm.com/servers/eserver/serverproven/compat/us/.
Notes:
vIf you are installing only one switch module, use I/O-module bay 1.
vConfiguration requirements for the switch module and the BladeCenter unit might
vary. You can obtain up-to-date information about the switch module and the
BladeCenter unit at http://www.ibm.com/systems/bladecenter/.
Installation guidelines
Before you install the switch module in the BladeCenter unit, read the following
information:
vRead the safety information that begins on page v, “Handling static-sensitive
devices” on page 6, and the safety statements in the BladeCenter unit
documentation. This information will help you work safely.
vObserve good housekeeping in the area where you are working. Place removed
covers and other parts in a safe place.
vBlue on a component indicates touch points, where you can grip the component
to remove it from or install it in the blade server or BladeCenter unit, open or
close a latch, and so on.
vOrange on a component or an orange label on or near a component on the
switch module, blade server, or BladeCenter unit indicates that the component
can be hot-swapped, which means that if the BladeCenter unit and operating
system support hot-swap capability, you can remove or install the component
while the BladeCenter unit 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.
vYou do not have to turn off the BladeCenter unit to install or replace any of the
hot-swap modules on the front or rear of the BladeCenter unit.
vWhen you are finished working on the blade server or BladeCenter unit, reinstall
all safety shields, guards, labels, and ground wires.
