Obtaining Technical Assistance
Your system can include up to ten server modules (or blades). Each server module functions as an individual server encompassing up to two microprocessors,
up to two hot-pluggable hard drives, and up to six memory modules (see
). To function as a system, a server module is inserted into a chassis that
supports power supplies, fan modules, a management module (Dell™ Remote Access Controller/Modular Chassis [DRAC/MC]), a KVM switch module, and at
least one I/O module for network connectivity. The power supplies, fans, DRAC/MC, and I/O modules are shared resources of the server modules in the
chassis. In addition, your system may also ship with an optional external USB diskette drive and an optional external USB CD drive, which you can use to set
up and configure the server modules.
