rackmount configuration. The following is a general outline of the main features of the
R423-E3 chassis.
System Power
The R423-E3 chassis features a redundant 740W power supply composed of
two
separate power modules. This power redundancy feature allows you to replace a failed
power supply module without shutting down the system.
Hard Drive Subsystem
The R423-E3 chassis was designed to support eight hot-swap SATA
or SAS hard drives.
Front Control Panel
The control panel on the R423-E3 chassis provides you with system monitoring and
control. LEDs indicate system power, HDD activity, network activity, system
information
and power supply failure. A main power button and a system reset but- ton are also
included. In addition, two USB ports have been incorporated into the control panel to
provide front side USB access.
Cooling System
The R423-E3 chassis has an innovative cooling design that includes three 8-cm hot-plug
system cooling fans located in the middle section of the chassis. An air shroud channels
the airflow from the system fans to efficiently cool the processor area of the system. The
power supply module also includes a cooling fan.
