Sagem ADR 155C manual Connecting ports, Connecting Power Supply, Connection requirements

1 - INSTALLATION AND COMMISSIONING

1.3 - Connecting ports

The connections to be performed on the equipment depend on the configuration chosen:

On the power supply card:

poser supply ports: "PWR" or "PWRA" and/or "PWRB",

On the subrack motherboard strip:

management ports : "COMM", "ETH" and/or "MNGT"

Remote indication, remote control and station alarm port : "LOOPS"

2Mbit/s G.703 synchronization port : "SYNC"

21x2Mbit/s G.703 traffic ports: "E1 INPUT" and "E1 OUTPUT".

Depending on the traffic modules used

optical STM-1 ports and order wire channels ports,

SEthernet port

21x2Mbit/s G.703 traffic ports.

Connection requirements :

For a right distribution of cords on either side of the subrack, the connections of slots A and C, the 21 2Mbit/s accesses and synchronization access are oriented leftward. All other

÷connections are oriented leftward.

The run of cords must not hinder the extraction of a module; in particular, connecting cables of the left subrack half is to be secured to the frame with enough backlash to enable the ventilation module to be extracted during a maintenance operation.

1.3.1- Connecting Power Supply

"PWRA" and/or "PWRB" ports, when the equipment is powered from one or two 48 V

Ssources, the power source(s) should be limited to 100 VA.

. "PWR" port when the equipment is powered from a mains voltage (230 V AC), via an optional 110-240//48V 60W/ transformer.

Observe the following connection requirements :

"PWR" and "PWRA" and/or "PWRB" Power supply ports can be connected simultaneously.

The power cord or the 110-240//48V 60W/ transformer must not be connected to the primary

÷source prior to being connected to the equipment.

The 110-240//48V 60W/ transformer must be mounted far from any heat source, and no traction must be exerted on its connecting wires.
