Power Supply
The power supply consists of the power supply bay and one power supply module. A
second power supply module can be purchased to provide a redundant, 1+1 system.
With either configuration, the power supply provides 350 watts of power and is
designed to minimise EMI.
The power supply operates within the following voltage ranges and is rated as
follows:
100 - 120 V~ at 50/60 Hertz (Hz); 6.3A maximum
200 - 240 V~ at 50/60 Hz; 2.5A maximum
The power subsystem supports the implementation of remote management features,
including remote enable that permits power to be activated from a variety of sources.
System Cooling
The chassis includes two 80-mm non-hot-swappable system fans for cooling the
processor(s), hard drives, and add-in cards. A third fan may be added in the center
position to provide cooling redundancy for system components. The system fans are
mounted in a fan assembly located in the middle of the chassis to pull cooling air
through the chassis. The power supply contains a single fan for cooling.
Security
To help prevent unauthorised access to the system’s peripherals and control panel,
an optional key-locked front bezel can be used. The chassis also includes a
preinstalled intrusion switch that can be monitored by server management software.
When the cover is opened, a switch located on the front panel board transmits a
signal to the Baseboard Management Controller (BMC) on the server board.
Through server management software, the system can be programmed to respond
to an intrusion by powering down or by locking the keyboard. At the chassis level a
variety of security options are provided.
Rack and Cabinet Mounting Options
The SX220 chassis was designed to support 19” wide by up to 30” deep server
cabinets. The chassis comes equipped with a relay rack or cabinet mount kit that can
be configured to support front-mount or mid-mount 2-post racks and 4-post cabinets.
Viglen also provides an optional sliding rail kit that is used to mount the chassis into
a standard (19” by up to 30” deep) EIS 310D compatible server cabinet.
For mounting in a regular server cabinet, the front mount brackets are attached to
the front of the chassis, and a set of rear support brackets are attached to the back
end of the cabinet. This evenly distributes the server to prevent the mounting rails on
the cabinet from bending. Caution should be used in using the front mount-only
option. Even though the rail mount kit hardware was designed to support the weight
