v Power modules
v Fan modules
v Multiplexer expansion modules
v Alarm panel module
“Major components of the BladeCenter HT Type 8740 and 8750 unit” on page
See
11 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 HT
unit.
The BladeCenter HT unit and the active management module make optional I/O
devices (USB devices, keyboard, video, and mouse) available to all the blade
servers, selected by any one blade server at a time.
Blade servers
The BladeCenter HT unit provides 12 bays for blade servers or other BladeCenter
HT 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 HT unit and
shares power, fans, switches, and ports with other blade servers.
Media tray
The BladeCenter HT unit comes with one hot-swap media tray in media tray bay 1.
You can add a second media tray in media tray bay 2 to provide redundancy.
The media tray is a hot-swap module that provides two USB connectors for use by
the blade servers, error LEDs, an ambient air temperature sensor and a pressure
sensor for use by the advanced management module, and two CompactFlash bays.
Advanced management module
The BladeCenter HT unit comes with one hot-swap advanced management module
in management-module bay 1. You can add a second advanced management
module in management-module bay 2 to provide redundancy.
When installing an advanced management module into the BladeCenter HT
Note:
unit, an advanced management-module interposer must be installed into the
bay before installing the advanced management module.
The advanced management module is a hot-swap module that you use to configure
and manage BladeCenter HT components. See the User’s Guide that comes with
the advanced management module for more information.
Chapter 1. Introduction 5
I/O modules
Power modules
The BladeCenter HT unit has eight hot-swap I/O-module bays that are compatible
with three types of I/O modules (see “BladeCenter HT components and LEDs” on
page 18 for the location of the I/O module bays). These bays can be used as
follows:
Notes:
1. When installing an I/O module into the BladeCenter HT unit, an I/O-module
interposer must be installed into the bay before installing the I/O module.
2. When installing a high-speed I/O module into the BladeCenter HT unit, a
high-speed I/O-module interposer tray with interposer card must be installed into
the bay before installing the high-speed I/O module.
The modules in I/O bays 1 through 4 can be either of the following types:
v
– Switch modules
– Bridge modules
– Passthrough modules
The modules in I/O bays 7 through 10 support high-speed I/O modules.
v
The BladeCenter HT unit is configured with two or four hot-swap power modules.
Fan modules
Power modules are required in bays 1 and 2, and they supply power to blade bays
1 through 6, media trays 1 and 2, management-module bays 1 and 2, and
I/O-module bays 1 through 4.
Power modules are required in power module bays 3 and 4 if you install blade
servers in blade bays 7 through 12 or if you install I/O modules in any of
I/O-module bays 7 through 10.
Each pair of power modules operates as a redundant pair. If either power module
fails, the remaining power module continues to supply power, but there is no
redundancy; the failed power module must be replaced as soon as possible.
The BladeCenter HT unit comes with four hot-swap fan modules for cooling
redundancy. The fan module speeds vary depending on the ambient air temperature
within the BladeCenter HT unit, which is reported by the media tray. If the ambient
temperature is 25°C (77°F) or below, the BladeCenter HT unit fan modules will run
at their minimum rotational speed, increasing their speed as required to control
internal BladeCenter HT temperature. If the ambient temperature is above 25°C
(77°F), the fan modules will run faster, increasing their speed as required to control
internal BladeCenter HT unit temperature. Each fan module contains two fans
operating as a pair in a series. If one fan fails, the remaining fan will run at full
speed and continue to cool the BladeCenter HT unit. Replace a failed fan module
as soon as possible, to restore cooling redundancy.
Attention: If more than two fan modules are removed or more than two fan
modules experience a double fan failure, the blade servers will shut down within 1
to 3 seconds.
Multiplexer expansion modules
The BladeCenter HT unit comes with two hot-swap multiplexer expansion modules
for redundancy. The multiplexer expansion module controls the USB connectors,
6 BladeCenter HT Type 8740 and 8750: Installation and User’s Guide
video signal, console redirection, and status LEDs on the BladeCenter HT unit.
Replace a multiplexer expansion module as soon as possible, to restore
redundancy.
Alarm panel module
The BladeCenter HT unit comes with an alarm panel module. The alarm panel
provides telecom relays and LED alarm status with additional functionality of a
serial console through the serial port on each blade server in the chassis using an
external breakout cable.

Power modules 1 and 2 are redundant and provide power to blade bays 1 through
6, while power modules 3 and 4 are redundant and provide power to blade bays 7
through 12. To ensure power redundancy, a typical power configuration is to supply
power to power connectors 1 and 4 from one power source location, while
supplying power to power connectors 2 and 3 from another power source location.
Important: The release handles on the fan shuttle have a safety switch that
disables power output from the power boxes. If the release handles are not secured
to the chassis with the thumbscrews, the BladeCenter HT unit will not power on.
