XG12 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.
- 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 XG12 chassis or restart a software program in the event the XG12 chassis operation is upset or stopped by electrostatic discharge.
Note: After removing or installing this cover, ensure that the thumbscrews are tightened down with a screwdriver.

Supported Modules
The modules that are supported on the XG12 are listed in the following table.
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.
The hot-swap procedure is detailed in Appendix D Hot-Swap Procedure.
SFF Adapter Module
The XG12 adapter module allows Ixia Standard Form Factor (SFF) load modules to be adapted into the XG12 chassis. The following figure shows an SFF adapter module.
Figure: SFF Adapter

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.
The following figure shows an SFF Adapter module with a legacy ATM card.
Figure: SFF Adapter with ATM Module

The table in section Supported Modules identifies the modules that can be used with the SFF Adapter.
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 BIOS on the XG12 is set to Power On after a power failure.
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.
Précautions relatives au montage en rack
Caution:
Si cette unité est installée dans une baie d’équipement réseau, observer les précautions suivantes:
- Température ambiante élevée: si installée dans un assemblage de baie fermé ou contenant plusieurs unités, la température ambiante de l’installation peut etre plus élevée que la température ambiante de la pièce. En conséquence, penser a installer l’équipement dans un environnement compatible avec la température ambiante maximale autorisée (40 C) spécifiée pour l’appareil.
- Circulation d’air réduite: installer l’équipement dans une baie de manière a ce que la circulation d’air requise pour faire fonctionner l’équipment en toute sécurité ne soit pas réduite. Ne pas bloquer les côtés de l’appareil, et laisser approximativement un espace de 12 pouces, de préférence 24 pouces, de chaque côté de l’unité pour une ventilation adéquate. L’espace laisse libre pour la circulation de l’air doit être de 12 pouces de chaque côté.
- Montage mécanique: monter l’appareil de manière a s’assurer qu’il soit droit dans la baie afin d’éviter de créer une condition dangereuse
- Un soin particulier doit etre apporté au branchement de l’équipement au circuit d’alimentation et aux conséquences qu’une charge excessive des circuits pourrait avoir sur le système de protection contre les surcharges et sur le cablâge d’alimentation. Prendre des précautions d’usage en prêtant attention aux normes figurant sur la plaque d’identification de l’équipement.
- Mise a la terre fiable: maintenir une mise a la terre fiable de l’équipement monté en baie. L’appareil doit etre vissé sur la baie afin d’assurer une mise a la terre correcte. De plus, faire particulièrement attention aux alimentations en courant autres que celles provenant de connections directes au circuit de dérivation (par exemple utilisation de prises multiples).
- Le remplacement du cordon d’alimentation doit comporter le même type de cordon et le même type de prise que ceux livrés avec l’unité.
