Chapter 6: XG12 Chassis

This chapter provides details about the XG12 chassis—its specifications and features.

The XG12 Chassis is the next generation high performance platform capable of supporting all XM form factor load modules, including full chassis configurations of the Xcellon load modules. It is a 12-slot chassis with increased total power capacity available for all load modules and front-to-back airflow delivery along with increased bandwidth from the CPU to the load modules.

The chassis provides improved modularity and access to the major components to reduce downtime of a failed chassis and to reduce the probability of needing to remove a failed chassis from the test environment. The four separate modules that make up the chassis are shown in Table 6-1.

Table 6-1. XG12 Part Numbers and Modules
Part Number	Description
941-0017	XG12, 12-Slot Chassis Frame Module

Hot-Swap Procedure

Each XG12 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.

SFF Adapter Module

The XG12 adapter module allows Ixia Standard Form Factor (SFF) load modules to be adapted into the XG12 chassis. Figure 6-3 shows an SFF adapter module.

A SFF load module is inserted into the front of the adapter and connects to the pins in the rear of the adapter. The entire assembly can then be inserted into any XG12 chassis slot.

Once an adapter module is installed in a chassis, SFF load modules can be hot-swapped without removing the SFF load module from the chassis.

Cooling Fan Speed Control

The XG12 chassis automatically monitors and measures the temperature of installed load modules. The XG12 automatically adjusts the fan speed to maintain proper cooling.

Power outage recovery and Automatic booting scenario

The XG12 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 is it 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.
