1-3 Server Chassis Features
The following is a general outline of the main features of the SC823S-550LP/
SC823i-550LP chassis.
System Power
When confi gured as the 5025M-4+/5025M-i+, the SC823S-550LP/SC823i-550LP
chassis includes a single 550W power supply.
SCSI Subsystem (5025M-4+ only)
The SCSI subsystem supports six 80-pin SCA Ultra320 SCSI hard drives. (Any
standard 1" drives are supported. SCA = Single Connection Attachment.) The SCSI
drives are connected to an SCA backplane that provides power, bus termination
and confi guration settings. The SCSI drives are also hot-swap units.
Control Panel
The SC823S-550LP/SC823i-550LP control panel provides important system moni-
toring and control information. LEDs indicate power on, network activity, hard disk
drive activity and system overheat conditions. Also present are a main power button
and a system reset button.
I/O Backplane
The backplane of the SC823S-550LP/SC823i-550LP supports the use of up to
seven low-profi le expansion cards and provides one COM port, one VGA port, two
USB ports, PS/2 mouse and keyboard ports and two Gb Ethernet (LAN) ports.
Cooling System
The SC823S-550LP/SC823i-550LP chassis' revolutionary cooling design that in-
cludes four 8-cm system cooling fans. The fans plug into chassis fan connectors
that are located behind the drive bays. A "Fan Speed Control Mode" setting in
BIOS allows the user to set the chassis fan speed [recommended setting is "4-
pin (Server)]". If any fan fails and the ambient air temperature inside the chassis
becomes too high, an overheat LED and alarm will be activated. The system also
includes an air shroud to maximize airfl ow effi ciency.
