You must install the NTP Output Connector module (part number 090-55594-02) in
the output group that corresponds with the front panel slot in which the NTP Server
card is installed. The NTP Output Connector module spans the top and bottom
locations for each output group.

2. Carefully seat the module onto the shelf.
