XGS12 Chassis Installation Precautions

The chassis should be installed in the rack before installing the power supply module, fan module and load modules, thereby reducing the weight of the chassis.

The two lower bolts used to secure the chassis to a rack can be used to hold the chassis frame in place while securing all of the other bolts (See Figure 6-2).

Secure the chassis to rack face with all six bolts. Fully depress power supply clamps when installing power supply module.

Secure the power supply module thumb bolt when installing power supply module.

Install the rear power supply cover before applying AC power.

Note: After removing or installing this cover, ensure that the thumbscrews are tightened down with a screwdriver.

Do not use the chassis without installing the Fan module.

Do not use the chassis without installing the Processor module.

Do not leave unused slots open. Use the filler panels to cover the un-used slots. See Installing Filler Panels for more information.

Do not block the front air intake.

A minimum air flow clearance of 12 inches is required. 24 inches of air flow clearance is preferred at the rear of the chassis.

Operator intervention may be required to power cycle the XGS12 chassis or restart a software program in the event the XGS12 chassis operation is upset or stopped by electrostatic discharge.

Hot-Swap Procedure

Each XGS12 chassis provides the ability of removing and reinstalling a load module without requiring the removal of power from the rest of the chassis. The process of removing/installing a Load Module does not impact either the operation of the OS or remaining load modules installed in the chassis.

Cooling Fan Speed Control

The XGS12 chassis automatically monitors and measures the temperature of installed load modules. The XGS12 automatically adjusts the fan speed to maintain proper cooling.

Power outage recovery and Automatic booting scenario

The XGS12 chassis will start up, boot Windows 7 and automatically login to the Ixia user account. Anything that is in the Startup folder will also launch..

Rack Mount Cautions


Caution: If this unit is installed in a network equipment rack, please observe the following precautions.

Elevated Operating Ambient Temperature: If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, consider installing the equipment in an environment that is compatible with the maximum allowable ambient temperature specified for the chassis (40° C).

Reduced Air Flow: Install the equipment in a rack so that the amount of air flow required for safe operation of the equipment is not reduced. Do not block the back or the front of the chassis, and leave approximately 12 inches of space, 24 inches preferred, for the back of the unit for proper ventilation. The air flow clearance should be 12 inches on the front.

Mechanical Loading: Mount the chassis so that it is level in the rack and that a hazardous condition is not caused. Please install all six mounting bolts.

Circuit Overloading: Consider the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Pay attention to equipment nameplate ratings when addressing this concern.

Reliable Earthing: Maintain reliable earthing (grounding) of rack-mounted equipment. Chassis frame should be screwed down to racks to ensure proper grounding path. In addition, pay special attention to supply connections other than direct connections to the branch circuit (such as use of power strips).

Replacement of the power supply cord must of the same type cord and plug configuration that was shipped with the unit.
