PSU
The PSU is located in the bottom middle of the cabinet or in an equipped high cover. The PSU has all
the voltages required for the WRH. It has capacity for the radio circuitry, fiber optics, modem, etc., and
also supplies the BA if used. Multi-band WRH-Vs always require a second PSU. There are two PSU
types with different input voltages:
Port Description
P101 SMA, electrical RF input port (to the optical TX port)
P102 SMA, electrical RF output port (from the optical RX port)
P103 SMA, electrical RF output port (15dB below the P102 port)
RX DIN/APC, optical input port (to the P102 and P103 RF ports)
TX DIN/APC, optical output port (from the P101 RF port)
P104 Used only for development and debugging
P105 4-pin male, door LED indicators. Used for the yellow and red LED indicators located
on the front cabinet door
P106 9-pin D-sub female, RS-232 used for local PC communication
P108/116 6-pin male, parallel connected power ports for the FON
P109 7-pin male, used for external alarm sensors
P110 W-link jumper, used to terminate units in a W-link. It has to be set in the parking
state for all units except for the first and last units in a W-link. The Parking state (P)
has the jumper between the center and bottom pins. The opposite state (T) termi-
nates the W-link.
P111/112 5-pin male, WLI ports used for interconnecting nodes in WLI-nets (IP or R2R net-
works). They are identical and connected in parallel. One of the connectors are
intended to be used from the previous node and the other connector to the next
node in the network. Either can be used for the first and the last unit in the net chain.
P113 2-pin male, used for the on-PCBA backup batteries.
P114 Backup power output jumper, sets the backup power output state. The OFF state
has jumper between the center and left pins. This jumper has to be in the OFF state
when used in an OCM. Otherwise, it shall be in the ON state.
P115 3-pin male, future port - intended for future use
P117 SMA, electrical RF input port (15dB below the P101 port)
P130 34-pin, 2-line male, RCU port used for connecting an RCU. The connector contains
both the modem connection and RCU power supply.
