1. Place the access panel on top of the server with the hood latch open.

2. Push down on the hood latch. The access panel slides to a closed position.

After performing the SDR PCIx Host card installation procedure, slide server back into the rack:

1. Press the server rail-release latches and slide the server fully into rack.

2. Secure the server by tightening the thumbscrews.

Optical and electrical connections with the remote unit and GPS are supported by four optical
and two electrical ports. The electrical interface to the GPS is through coaxial cable connections
using two type SubMiniature version A (SMA) female connectors. Single-mode fiber provides
the optical connection between the SDR PCIx Host Card and Remote Units. The forward and
reverse ports provide the optical communication channel in a non-diversity system. The REV
DIV port provides receive optics for a diversity system. Each optical port uses a small form
factor LC-type optical transceiver. Modular optical transceivers are field replaceable and
available separately. 

The SDR PCIx Host card is equipped with SMA-type female 50-Ohm connectors for connecting
the timing input/output signals from the GPS unit. High performance, flexible, low loss 50-ohm
coaxial communications cable (RG316 or equivalent) should be used for all coaxial connections.

The RF interface between SDR PCIx Host card and the GPS is supported through a pair of type
SMA female connectors mounted on the DHU front panel. One connector provides the coaxial
cable connection for the REF (10 MHz sine wave) signal. The other connector provides the
coaxial cable connection for the PPS (1 pulse per second) signal. Use the following procedure to
install the coaxial cables and connect them to the DHU:

1. Obtain the required lengths of high performance, flexible, low loss 50-ohm coaxial

communications cable (RG316 or equivalent) for all coaxial connections.
