Server Chassis Features
The 5028R-WR is built upon the SC825TQ-R500WB chassis. Details on the chassis
and on servicing procedures can be found in Chapter 6. The following is a general
outline of the main features of the chassis.
System Power
The SC825TQ-R500WB features a redundant 500W power supply consisting of
two power modules. The system does not need to be shut down when replacing or
removing a single power supply module.
Hard Drive Subsystem
The SC825TQ-R500WB chassis was designed to support eight hot-swap SATA
hard drives.
Front Control Panel
The control panel on the SuperServer 5028R-WR provides you with system monitor-
ing and control. LEDs indicate system power, HDD activity, network activity, system
overheat and power supply failure. A main power button and a system reset button
are also included. In addition, two USB ports have been incorporated into the control
panel to provide front side USB access.
Cooling System
The SC825TQ-R500WB chassis has an innovative cooling design that includes
three 8-cm hot-plug cooling fans located in the middle section of the chassis. These
fans are powered by 4-pin connectors with fan speed controlled by IPMI software.
An air shroud channels the airflow from the system fans to efficiently cool the pro-
cessor area of the system. The power supply module also includes a cooling fan.
