Make sure you refer to the section that describes the PRU deployed in your installation.

"Bottom of an

AC-Powered Quad-Bay PRU” on page 8

and

"DC-Powered Quad-Bay PRU” on page 9

shows the differences

between an AC-powered and a DC-powered PRU. The differences will be the same for Single-Bay, Dual-Bay, and
Tri-Bay chassis. Additionally, for both the AC-Powered and DC-Powered PRUs:

•

The number of Antenna connectors on the bottom of a PRU corresponds to the number of RF Module bays in
that PRU model, where there are two Antenna connectors per bay. For example:

–

There are four RF Module bays in a Quad-Bay PRU, so there are eight Antenna connectors.

–

There is one RF Module bay in the Single-Bay PRU, so there are two Antenna connectors.

•

The Single-Bay PRU only has one Fiber connector whereas the other three PRU models have two.
