ADC Telecommunications Inc. PSM1900M Manual De Usuario

Before you install the RF Module cables, familiarize yourself with the rules that pertain to these
cables, as defined in the following sections.
Always provided at each RF Module shelf are five cables:

two High‐Speed Data Cables, which in this document are referred to as LVDS (Low‐Voltage
Differential Signaling) cables

two RF Cables (TX0/RX0) and (TX1/RX1)

one Power (PWR) Cable.

Maintain adequate strain relief distances from the connection points to the module.

LVDS cables labeled PRIM and DIV should always either be connected to a RF Module or strain
relieved to adjacent cables, as this protects the cable against damage through misplacement.

Align and fully insert the LVDS cable connectors into their respective connector cages. Full
insertion is identified by an audible click.

Ensure the two LVDS cables are fully seated and latched into their respective receptacles on
the RF Module by lightly pulling outward on the connectors. If fully seated and locked into
position, the cable connectors will not slide back out.

Maintain adequate strain‐relief distances from the connection points to the RF Module.

The RF Module cables that are pre‐installed in the PRU connect to the corresponding connectors
on the RF Module. The RF Module cables correlate to the antenna connectors on the bottom of the
PRU chassis.
