Configuring the Coding Modules of a MIMO System
Complete the following steps to continue configuring the modules if you chose to add the coding option for a MIMO mmWave Transceiver System.
For unidirectional systems, the coding option includes one coding chassis that connects to the RX chassis. For bidirectional systems, the coding option includes two coding chassis that connect to the two RX/TX chassis. Both systems require you to move the PXIe-7902 module from slot 12 of the RX or main chassis to slot 9 of the coding chassis.
-
Ensure the AC power source is connected to every chassis before removing and installing the module.
The AC power cord grounds the chassis and protects it from electrical damage while you remove and install the module.
- Power off the chassis.
-
Remove the slot blocker from slot 9 of the coding chassis.
Note Do not discard the slot blocker.
-
Locate the PXIe-7902 in slot 12 of the RX or RX/TX chassis and remove it.
- Remove the Mini-SAS HD(m)-to-Mini-SAS HD(m) (8.25 in.) cables that are attached to the PXIe-7902 front panel.
- (Optional) Remove the Mini-SAS HD(m)-to-Mini-SAS HD(m) (8.25 in.) cable that connects the PXIe-7902 modules in slots 9 and 18. Removing this cable makes it easier to remove the PXIe-7902 module in slot 12.
- Unscrew the two bracket-retaining screws in the front panel.
- Press the injector/ejector handle down.
- Slide the PXIe-7902 module out of slot 12 of the chassis.
- Fill slot 12 of the RX or RX/TX chassis using the slot blocker you removed in step 3.
-
Locate the empty slot in slot 9 of the coding chassis and install the PXIe-7902 module you removed in step 4.
- Inspect the slot pins on the chassis backplane for any bends or damage prior to installation. Do not install a module if the backplane is damaged.
- Touch any metal part of the chassis to discharge static electricity.
- Place the PXIe-7902 module edges into the module guides at the top and bottom of the chassis. Slide the module into the slot until it is fully inserted.
-
Secure the PXIe-7902 module front panel to the chassis using the front-panel mounting screws.
Note Tightening the top and bottom mounting screws increases mechanical stability and also electrically connects the front panel to the chassis, which can improve the signal quality and electromagnetic performance.
-
Reconnect the modules you disconnected in step 4.a using Mini-SAS HD(m)-to-Mini-SAS HD(m) (18 in.) cables.
- Connect the PORT 4 connector of the PXIe-7902 front panel in slot 9 of the RX or RX/TX chassis to the PORT 4 connector of the PXIe-7902 front panel in slot 9 of the coding chassis.
- Connect the PORT 4 connector of the PXIe-7902 front panel in slot 18 of the RX or RX/TX chassis to the PORT 5 connector of the PXIe-7902 front panel in slot 9 of the coding chassis.
- If you chose to remove the third cable in step 4.b, replace it now by using a Mini-SAS HD(m)-to-Mini-SAS HD(m) (8.25 in.) cable to connect the PORT 5 connector of the PXIe-7902 front panel in slot 9 of the RX or RX/TX chassis to the PORT 5 connector of the PXIe-7902 front panel in slot 18 of the RX or RX/TX chassis.
- Connect the PORT 1 connector of the PXIe-7902 front panel in slot 9 of the coding chassis to the PORT 1 connector of the PXIe-7902 front panel in slot 18 of the coding chassis using a Mini-SAS HD(m)-to-Mini-SAS HD(m) (8.25 in.) cable.
- Power on the chassis.
- If you have a bidirectional system, repeat steps 1 through 10 for the second set of chassis.
