Notes:
  1. 2-way blade server installs in a BladeCenter chassis. KVM support
    is not provided; use serial over LAN communication to perform local,
    network operating system or software installation as an alternative
    to KVM. Up to 14 JS20 blade servers are supported in the BladeCenter
    chassis and up to 8 JS20 blade servers are supported in the BladeCenter
    T chassis. Power modules in BladeCenter models 1XX will need to
    be upgraded to 1800w power modules in order to support JS20 blade
    servers.
  2. PowerPC 970 processors with full-speed L2 cache. All models
    have a 1.1GHz Front-side Bus (FSB).
  3. Memory is two-way interleaved, PC2700 ECC DDR RDIMMs.
  4. System management functionality, interconnect network connectivity
    and console connectivity are managed through the standard management
    module. The standard integrated service processor monitors JS20
    system management activity, communicating with the management module
    in the BladeCenter.
  5. Broadcom dual-port integrated copper gigabit Ethernet controller.
  6. Maximum HDD storage capacity is based on installation of two
    60GB 5400rpm ATA-100 HDDs.
  7. Installation of an I/O expansion card prevents installation
    of a 2nd IDE HDD.
  8. NEBS compliant.
  9. Maximum memory capacity is based on installation of four 2GB
    PC2700 ECC DDR DIMMs.
