Chapter 2. Preparing The Bladecenter Unit; Preinstallation Checklist - IBM eServer BladeCenter JS20 Type 8842 Installation And User Manual

Chapter 2. Preparing the BladeCenter unit

This chapter describes the tasks that you must perform before you can use the
BladeCenter unit with the blade server.

Preinstallation checklist

Before you can use the BladeCenter unit with the blade server, you must correctly
set up and configure the BladeCenter unit, and install and configure the required
components in the BladeCenter unit. If you have not already done so, perform the
activities on the following checklist:
__ 1. Set up the rack in which you will install the BladeCenter unit.
__ 2. Install the BladeCenter unit in a rack. For additional information, see the
__ 3. Install and configure the required BladeCenter unit components:

Rack Installation Instructions that come with the BladeCenter unit.
__ a. Make sure that the BladeCenter unit has adequate power to support
all the installed devices. The BladeCenter unit must contain either two
or four power modules. If necessary, upgrade the power modules in
the BladeCenter unit. For additional information, see the IBM
Eserver BladeCenter Power Module Upgrade Guidelines Technical
Update.
__ b. Install and configure one or two management modules in the
BladeCenter unit.
__ c. Install and configure one or two Ethernet switch modules in the
BladeCenter unit.
To support the Serial Over LAN (SOL) feature on any blade server
that is installed in the BladeCenter unit:
v A SOL-compatible Ethernet switch module must be installed in I/O
bay 1 of the BladeCenter unit.
v Both the BladeCenter unit and the Ethernet switch module must be
configured so that the SOL feature is enabled and set to operate on
the same virtual local area network (VLAN).
If you plan to install the operating system through the Ethernet
network, you also must install and configure a second Ethernet switch
module in I/O bay 2 of the BladeCenter unit.
Note: If you install other Ethernet switch modules, they do not have
to be the same type that you installed in I/O bay 1 of the
BladeCenter unit.
__ d. Configure the BladeCenter unit for SOL operation as described in the
IBM Eserver BladeCenter and BladeCenter T Serial Over LAN Setup
Guide.
Verify that the firmware code for the BladeCenter unit, management
module, and Ethernet switch modules supports the SOL feature. If you
are not sure whether these devices come with this feature, see the
IBM Eserver BladeCenter and BladeCenter T Serial Over LAN Setup
Guide for additional information.
The SOL feature is required and must remain enabled for all
applicable devices, including the BladeCenter unit, management
module, and Ethernet switch modules.
