Blade server expansion options
Some blade servers contain connectors for options that add capabilities to the blade
server. You can add these options before installing the blade server in the
BladeCenter unit.
Go to http://www.ibm.com/pc/compat/ on the World Wide Web for a list of available
options for your IBM blade server.
I/O expansion option
Some blade servers have connectors for adding an I/O expansion option, such as
the IBM HS20 Fibre Channel Expansion Card. The BladeCenter unit routes network
communication signals from the I/O expansion option to I/O modules 3 and 4 on the
BladeCenter unit. The I/O expansion option is attached directly to the blade server
but does not occupy an additional blade bay.
Note: If an I/O expansion option is installed on any blade server, I/O modules
compatible with that network interface must be installed in I/O-module bays 3
and 4 on the BladeCenter unit. See “I/O modules” on page 16 for more
information.
Storage-expansion option
Some blade servers have a connector for adding a SCSI expansion unit, such as
the IBM HS20 SCSI Storage Expansion Unit. The storage expansion unit supports
up to two hot-swap SCSI hard disk drives. The expansion option is attached directly
to the blade server; the blade server and expansion option together use two blade
bays.
Installing a blade server
Complete the following steps to install a blade server in the BladeCenter unit.
Statement 21:
CAUTION:
Hazardous energy is present when the blade is connected to the power
source. Always replace the blade cover before installing the blade.
