See "Major components of the BladeCenter H unit" on page 9 for the location of each module. These modules supply common functions to the blade servers that are installed in the blade bays in the front of the BladeCenter unit. The BladeCenter unit and the active management module make optional I/O devices (optical drive, USB port, keyboard, video, and mouse) available to all the blade servers, selected by any one blade server at a time. Advanced management module The BladeCenter unit comes with one hot-swap management module in management-module bay 1. You can add a second management-module in management-module bay 2 to provide redundancy. The management module is a hot-swap module that you use to configure and manage BladeCenter components. See the User's Guide that comes with the management module for more information. I/O modules The BladeCenter unit has 10 hot-swap I/O module bays that are compatible with three types of I/O modules (see "Rear view" on page 15 for the location of the I/O module bays). These bays can be used as follows: v The modules in bays 1 and 2 such as Ethernet switches or pass-thru modules, provide a communication links for the first and second network interface controllers (NICs) on each blade server. The modules in these bays must support Ethernet. v The modules in bays 3 and 4 can be either of the following types, but the modules in both bays must be of the same type: - Switch modules, which provide a communication link for the third and fourth NICs in each blade server. The modules in these bays must support the type of network interface that is used in the corresponding blade-server NICs. When these bays are used this way, they are similar in function to bays 1 and 2. - Bridge modules, which provide links to bays 7 through 10 that can be used as additional outputs for the I/O modules in those bays. When these bays are used this way, the modules in these bays are not directly linked to the blade servers but bay 3 provides redundancy for the module in bay 5 and bay 4 provides redundancy for bay 6. v The modules in bays 5 and 6, such as bridge modules, provide links to bays 7 through 10 that can be used as additional outputs for the I/O modules in those bays. Bays 5 and 6 are not directly linked to the blade servers. v The modules in bays 7 through 10, such as Infiniband switches, provide high-speed communication links to the fifth through eighth NICs in each blade server. The modules in these bays must support the type of network interface that is used in the corresponding blade-server NICs. Blade servers The BladeCenter unit provides 14 bays for blade servers or other BladeCenter devices. A blade server is a hot-swap, independent server with its own processors, memory, storage, network controllers, operating system, and applications. The blade server is installed in a bay in the BladeCenter unit and shares power, fans, switches, and ports with other blade servers. 4 BladeCenter H Type 8852, 7989, and 1886: Installation and User's Guide

See “Major components of the BladeCenter H unit” on page 9 for the location of
each module. These modules supply common functions to the blade servers that
are installed in the blade bays in the front of the BladeCenter unit.
The BladeCenter unit and the active management module make optional I/O
devices (optical drive, USB port, keyboard, video, and mouse) available to all the
blade servers, selected by any one blade server at a time.
Advanced management module
The BladeCenter unit comes with one hot-swap management module in
management-module bay 1. You can add a second management-module in
management-module bay 2 to provide redundancy.
The management module is a hot-swap module that you use to configure and
manage BladeCenter components. See the
User’s Guide
that comes with the
management module for more information.
I/O modules
The BladeCenter unit has 10 hot-swap I/O module bays that are compatible with
three types of I/O modules (see “Rear view” on page 15 for the location of the I/O
module bays). These bays can be used as follows:
v
The modules in bays 1 and 2 such as Ethernet switches or pass-thru modules,
provide a communication links for the first and second network interface
controllers (NICs) on each blade server. The modules in these bays must support
Ethernet.
v
The modules in bays 3 and 4 can be either of the following types, but the
modules in both bays must be of the same type:
–
Switch modules, which provide a communication link for the third and fourth
NICs in each blade server. The modules in these bays must support the type
of network interface that is used in the corresponding blade-server NICs.
When these bays are used this way, they are similar in function to bays 1 and
2.
–
Bridge modules, which provide links to bays 7 through 10 that can be used as
additional outputs for the I/O modules in those bays. When these bays are
used this way, the modules in these bays are not directly linked to the blade
servers but bay 3 provides redundancy for the module in bay 5 and bay 4
provides redundancy for bay 6.
v
The modules in bays 5 and 6, such as bridge modules, provide links to bays 7
through 10 that can be used as additional outputs for the I/O modules in those
bays. Bays 5 and 6 are not directly linked to the blade servers.
v
The modules in bays 7 through 10, such as Infiniband switches, provide
high-speed communication links to the fifth through eighth NICs in each blade
server. The modules in these bays must support the type of network interface
that is used in the corresponding blade-server NICs.

The BladeCenter unit provides 14 bays for blade servers or other BladeCenter
devices. A blade server is a hot-swap, independent server with its own processors,
memory, storage, network controllers, operating system, and applications. The blade
server is installed in a bay in the BladeCenter unit and shares power, fans,
