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.
Note: When installing an advanced management module into the BladeCenter HT
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.
