The SLSC-12001 chassis is designed for use with any SLSC module designed in accordance with the SLSC Module Design Specification 1.0. The SLSC-12001 chassis must be powered by an external power supply as described in the Chassis Power section of this document. The chassis allows communication between a host system and the SLSC modules in order to configure them. Additionally a Data Acquisition (DAQ) System, such as PXIe or cRIO, can be connected to SLSC modules through an RTI.

Figure 3 shows the SLSC-12001 chassis block diagram.
Figure 3. SLSC-12001 Chassis Block Diagram
The chassis power comes from an external +24 V supply and is distributed to each SLSC module through an internal power bus. The +24 V bus has input overvoltage, reverse voltage, and short circuit protection at each SLSC module output. The chassis does not have a power switch, therefore power is energized as soon as the external power supply is connected to the chassis and powered.
The SLSC-12001 chassis communicates with each module through the SLSC interface and manages the Ethernet connectivity with a host computer.
The SLSC-12001 chassis also has built-in diagnosis functions, such as battery and fan monitoring, that is accessible through the NI-SLSC driver. The chassis will shut down the 24 V rail supplied to the module unless all 5 fans are powered.

An optional secondary backplane, RTI, may be used with the SLSC-12001 chassis to route conditioned I/O signals directly to the DAQ system. The RTI can be used to distribute additional power to one or more modules as shown in Figure 4.
Figure 4. Rear Transition Interface
RTIs must be implemented as follows:
1. All slots must have the SLSC Peripheral Rear I/O Area covered by either an RTI or rear
2. RTI implementation is flexible and can be used as follows:
filler panel to meet EMC and airflow requirements.
• An RTI can be a single slot width therefore resulting in 12 RTIs.
• An RTI can be a single PCB 12 slots wide taking into account all slots.
• An RTI can cover any number of slots from 1 to 12.

The SLSC-12001 chassis is designed to operate in an instrument rack with cooling clearances to allow for proper airflow circulation.
Caution The SLSC-12001 chassis must be installed in a rack or similar enclosure
that ensures the rear of the chassis is not accessible (per IEC 61010-1) during normal use. Access to the RTIs must require a tool. The front of the chassis may remain accessible. Additionally, the rack or enclosure must meet the enclosure requirements of IEC 61010-1 for containing the potential spread of fire from the RTIs.
The SLSC-12001 chassis cooling inlet air vents are located on the front lower side of the chassis and the outlet air vents are on the back upper side of the chassis. Position the air inlet to pull air from outside the instrument rack. For best performance the air vents must allow easy air circulation without wiring or panels blocking the vents. Refer to Figure 5 for airflow and clearance information.
Figure 5. SLSC-12001 Chassis Airflow
1 Airflow Out 2 Airflow In
In order to operate the chassis at the maximum allowable ambient temperature and maximum power as specified in the Environmental section, you must mount the chassis horizontally in the rack and allow for airflow at the intake and exhaust as shown in Figure 5. Filler panels, which are available at
ni.com, must be inserted in any empty front module slots and in any empty rear
RTI slots.

Installing Rear Transition Interfaces
Caution Do not touch or remove the I/O boards or cables while the system is
energized. I/O boards may have exposed hazardous live voltages. Access must be prevented in normal operation
Note Refer to RTI manufacturer documentation for product-specific installation
instructions.
NI recommends installing all RTIs prior to the initial module installation. Complete the following steps to install RTIs:
1. Power off the main DC power source or disconnect it from the chassis before installing any RTI.
2. Ensure that the chassis is powered off. The POWER LED should be off. If it is not off, do not proceed until the POWER LED is off.
3. Loosen the screws of the upper rear panel. Refer to Figure 2 for the upper rear panel screws locations.
4. Position the RTI at the desired slot and insert the securing screws, but do not fully tighten them.
5. Insert a corresponding module in the same slot providing additional resistance at the rear of the RTI for the module to fully mate to the RTI.
6. Repeat steps 4 and 5 for all required RTIs.
7. Tighten the screws for all RTIs and the upper rear panel. This ensures proper alignment for future connections between modules and these RTIs.
Installing SLSC Modules
Caution The SLSC-12001 chassis and the SLSC modules do not support hot
plug-in. The entire chassis must be powered down when a module is installed.
Complete the following steps to install an SLSC module in the chassis while referring to Figure 6:
Caution Power off the main DC power source or disconnect it from the chassis
before installing the module. To completely remove power, you must disconnect all power cables.
Note Refer to module and RTI documentation to ensure electrical compatibility for
rear I/O connections.
1. Ensure that the chassis is powered off. The POWER LED should be off. If it is not off, do not proceed until the POWER LED is off.
