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,
Ethernet 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
sources, 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.
