      Checkpoint (1 of 3)
      The IBM BladeCenter contains a redundant circuit path to connect all blades servers to the AMM and switching fabric through which of the following:
      Blade servers are interconnected by a system of shielded cabling     
      A Midplane, with redundant upper and lower halves, connects all blade servers and provides a path to the switching modules     
      Each blades server is independently connected to the AMM and switching modules    
      True/False: The Midplane for the BladeCenter H contains only the new high-speed 4x signaling fabric connectors.
      The IBM BladeCenter E Chassis supports up to 14 Blade Servers. With Power Supplies 1 and 2 installed, which blade servers, switch modules and management modules will receive power?
      All fourteen Blade Server slots, all four switch module slots, the two blowers, the two management module slots and the media tray.
      Blade Server slots 1 through 6, all four switch module slots, the two blowers, the two management module slots and the media tray.
      Blade Server slots 1 through 6, switch module slots one and two, one management module slot and the media tray.
