System Features
l Support for up to six server modules. The system can support from one to six server modules. If less than six modules are installed in the system, a
blank module is used. Blank modules are required for proper operation.
l System management module which provides access to systems management software features and the KVM switch.
¡ To access system management features, connect the null modem cable between the management port and an external PC. You may also obtain
system management information through a Web browser connected to the RJ45 management port. Systems management software monitors the
system and server module status.
¡ The system management module includes keyboard, video, and mouse connectors. The onboard KVM switch provides an onscreen display to
select a server module.
¡ Embedded systems management circuitry that monitors operation of the system fans, and critical system voltages and temperatures. The systems
management circuitry works in conjunction with your systems management software.
l Support for up to two network switch modules. Externally, each switch has four 10/100/1000 BASE-T Ethernet ports.
l Four hot-pluggable system fans.
l Two 1048-watt, hot-pluggable, redundant power supplies. The system can operate without power redundancy with six server modules and only one
power supply turned on.
Server Module Features
l One or two Intel® Pentium® III microprocessors with an internal operating speed of at least 1.26 GHz, a 512 KB cache, and a front-side (external) bus
speed of 133 MHz.
l A minimum of 128 MB of system memory, upgradable to a maximum of 2 GB by installing PCI 133 registered, SDRAM memory modules in the two memory
module sockets on the system board.
l Support for up to two 1-inch, internal Ultra3 SCSI hard drives.
l Integrated internal drive mirroring allows two SCSI disks to be mirrored through the integrated RAID controller.
l An external USB port to support either a 1.44-MB, 3.5-inch diskette drive or a USB CD drive. When either the diskette or USB CD drive is attached to the
server module during boot, the drive is designated as the first boot drive. This designation allows you to install software on the server module's hard
drives.
l An integrated VGA-compatible video subsystem with an ATI RAGE XL video controller. This video subsystem contains 8 MB of SDRAM video memory
(nonupgradable). Maximum resolution is 1600 x 1200 x 16.7 million colors (noninterlaced).
