IBM eServer BladeCenter 8677, Installation And User Manual

Page: 39 / 108

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 switch 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, switch modules
for that network interface must be installed in switch-module bays 3 and 4 on
the BladeCenter unit.
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.
1. Read the safety information beginning on page vii and “Installation guidelines”
on page 13 through “Handling static-sensitive devices” on page 14.
2. Install any options needed, such as disk drives or memory, in the blade server.
See the documentation that comes with the blade server for instructions.
3. Select the bay for the blade server.
Notes:
a. If a blade server has a SCSI storage expansion option installed on it, the
blade server and expansion option require two adjacent blade bays.
