2.3 Installing the HRR 4104
The HRR 4104 receiver module plugs into an HMC 4008 module carrier,
shown in Figure 2-1. Each HMC 4008 carrier can accommodate two half-slot
HRR 4104 modules. The receiver module is held in the carrier by blind mate
RF connectors on the carrier. You can place the HMC 4008 carrier into any
available position in the HLP 4200 Platform.

To provide leverage for the blind mate connections, install the HMC 4008
carrier into the HLP 4200 Platform before you install the HRR 4104 module
into the carrier. The HLP 4200 Platform can be powered and operating during
the installation process.
