12.3 Installing the antenna connector to the Compute Module and
routing the coax cable
Note: Depending on the configuration purchased, these steps will typically already have been
performed by NEC and the antenna connectors will have been pre-installed. These steps are being
provided for reference in case the Compute Module or Interface Board is swapped.
Important: The antenna coax cable must be installed after the Compute Module is installed onto the
Interface Board, but before the heatsink is installed.
1. Unscrew the antenna from the SMA type external antenna connector on the coax cable
and set aside.

2. Unscrew the hex nut from the external antenna connector and remove the two washers
and set aside.
