Electrical Grounding requirements for Multi-Chassis system configuration
To ensure consistent grounding:
- All equipment must be mounted and screwed in to grounded 19" racks.
- Equipment should not be powered via distribution units with isolated grounding.
If equipment grounding is not consistent, the software will detect this and shutdown to protect equipment from damage.
LEDs/LCD Display
The Optixia XM12 has the following set of front panel LEDs, for each load module slot:
Label | Color | Description |
---|---|---|
Power |
Green |
For each load module slot, the Power LED is illuminated when the board is being powered. When the Power LED is flashing, the board is being detected or initialized. |
In Use |
Amber |
For each load module slot, the Active LED is illuminated when a Load Module in a particular slot is owned by you. If you run traffic from IxExplorer, without taking port ownership, the In Use light is not illuminated. |
LCD Display
An LCD display is provided on the chassis to indicate the status of the chassis without an external display device (monitor). The LCD operates in two modes:
- Startup: The LCD displays messages from IxServer to indicate the operation of IxServer as it initializes.
- Run: The LCD display provides chassis information. Information displayed includes chassis name, IxOS version, IP address, primary/secondary, and chassis status.
Supported Modules
The modules that are supported on the Optixia XM12 are listed in the following table.
Hot-Swap Procedure
Each Optixia XM12 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 load modules installed in the chassis.
The hot-swap procedure is detailed in Appendix D, Hot-Swap Procedure.
SFF Adapter Module
The Optixia XM12 adapter module allows legacy modules to be fit into the XM12 chassis. The following figures shows an SFF adapter module.
Figure: SFF Adapter

A legacy module is inserted into the front of the adapter module and connects to the pins in the rear of the adapter. The entire assembly can then be inserted into any Optixia XM12 slot.
Once an adapter module is installed in a chassis, legacy load modules can be hot-swapped without removing the adapter 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 Supported Modules section identifies the modules that can be used with the SFF Adapter.
Installing Filler Panels
The airflow in an Optixia XM12 chassis is inefficient if load modules are installed in a few slots and the rest of the chassis is left open. For best cooling results, filler panels are required. It is required that filler panels are used in situations where the slots in the chassis are not all in use.
An empty Optixia XM12 chassis includes:
- 5 ea. 1-slot wide XM12 Filler Panel/Air Baffle units (p/n 652-0648-04)
- 1 ea. 6-slot wide XM12 Filler Panel/Air Baffle unit (p/n 652-0353)
Prerequisites for Filler Panel Installation:
- The technician should use industry-standard grounding techniques, such as wrist and ankle grounding straps, to prevent damage to electronic components on any Ixia Load Modules.
Filler Panel Installation Procedure:
Note: ESD Caution: Use industry-standard grounding techniques to prevent Electrostatic Damage to the delicate electronic components on the Ixia Load Modules.
Attention:
Décharges électrostatiques - Attention: Utilisez les techniques standard de mise à la terre pour éviter tout dommage électrostatique sur les composants électroniques fragiles des modules de charge Ixia.
Example: Slide the one-slot filler panel, with the Ixia logo at the top, into the correct slot. The panel slides in on the slot rails in the chassis. Secure the faceplate of the filler panel to the chassis with two of the supplied screws.
Note: Use extreme care to prevent damage to delicate electronic components on an adjacent load module.
Note: Not using filler panels could cause random failures in port operations or damage installed modules.
Cooling Fan Speed Control
The XM12 chassis automatically senses the temperature of specified modules and adjusts the cooling fan speed. If the system and board heat load is low enough, the cooling fan operates at a lower (quieter) speed.
The following modules have thermal sensors that report temperature readings:
- LSM1000XMS(R)12
- LSM1000XMV(R)16/12/8/4
- LSM10GXM(R)3
- NGY LSM10GXM2/4/8(R), LSM10GXM2/4/8XP, LSM10GXM(R)2/4/8S, and 10GBASE-T versions LSM10GXM(R)2/4/8GBT-01, NGY-NP2/4/8, and NGY SFP+ 2/4/8.
- LavaAP40/100GE 2P and LavaAP40/100GE 2RP
Other modules control the fan speed by means of a fixed speed setting. For a list of supported modules, see the table in Supported Modules section.
XM12 Sound Reducer Installation
The XM12 Sound Reducer (PN 942-0021) is an optional accessory that installs on the rear of the XM12 chassis to reduce the sound of the cooling fans. It reduces the sound by approximately 10 dB.
Refer to the following figure when performing the installation.
Figure: XM12 Sound Reducer Installation
Note: The chassis should be placed in a horizontal position, in a well-lighted work area.
- On the XM12 chassis rear, remove the four shoulder screws that hold the fan panel in place. Do not remove the fan panel.
- Attach the sound reducer mounting bracket to the fan panel using the same four shoulder screws removed in Step 1.
-
Slide the sound reducer onto the mounting bracket.
- Secure the sound reducer onto the mounting bracket using the four pan-head screws included in the XM12 Sound Reducer kit.
Install XM12 Chassis
The following steps describe the procedure of installing an XM12 chassis:
- On the XM12 chassis rear, remove the four shoulder screws (marked in red circles) that hold the fan panel in place. Do not remove the fan panel.
- Put two screws in the rack. Screw them in half way.
- Put the empty chassis into the rack.
- Reset the bottom of the empty XM12 chassis on top of the two screws. (refer to the area marked using red circles in the image below). The entire weight of the empty XM12 will be supported by these two screws.
- Locate the two holes above that line up with the rack and screw in the other two screws (preferably the upper hole or one right below that)
- Screw-in the bottom two screws all the way.
- Find two or four more screws and screw them in. Do this optionally, and only if the holes line up.
- Insert modules (ensure that any empty slots have the blank metal covers in them as marked in red in the image below).
Rack Mount Cautions
Caution:
If this unit is installed in a Rack Mount, 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 sides of the chassis, and leave approximately two inches of space around the unit for proper ventilation.
- Mechanical Loading: Mount the equipment in the rack so that a hazardous condition is not caused due to uneven mechanical loading.
- 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 be conducted by a Service Person. The same type cord and plug configuration shall be utilized.
