3.5.1 Mechanical installation
Figure 38 Chassis dimensions and clearances (dimensions in mm)
Respect the requested clearances for the wiring, in order to avoid damage to the connectors (mar-
ked with an*).

The installation of rack (optional) and chassis must enable the ventilation shown Figure 39 Ven-
tilation of the DBS chassis (cross-section). Do not obstruct the air inlets and outlets.
Stages
1. Choose the location where the equipment is to be assembled and unpack the standard rack. If its
top cover is fitted, remove it (quarter-turn screw).
Note: place the rack in such a way that the cable connections are accessible before the rack is installed
definitively.
2. Unpack the DBS chassis assembly and install it inside the rack. Fix and screw into place.
3. Unpack the DC/DC PSUs; install and plug them in the DBS chassis.
4. Carry out the electrical connection, cf. § 3.5.2 Electrical connection.
5. Carry out the client terminal connections, cf. § 3.5.3 Customer access connections (circuits
interfaces) and 3.5.4 Client access connections (ATM network interface).
6. Connect the RBS/DBS connection cable(s) cf. § 3.5.5 RBS/DBS Connection.
3.5.2 Electrical connection
Considerations
The DBS chassis is supplied from the rated DC voltage of 48V (minimum 35V, maximum 60V).
The cable connecting the external DC power source to the DBS sub-rack will have a minimum
cross-section of 3x10 mm2 and a maximum length of 20 meters.
The rack must be grounded to the general grounding system. For this, the rack mechanism will be
connected by a cable with a minimum cross-section of 16 mm2 , attached using a 6 mm bolt.
For the power supply block diagram, refer to Figure 40 DBS chassis power supply:
Figure 40 DBS chassis power supply
Note: The user must connect +48V or -48V to ground.
WHEN MAKING THE POWER CONNECTIONS, TURN OFF ALL DBS
CHASSIS EXTERNAL POWER SOURCES.

Stages (Figure 42 DBS sub-rack power connection)
1. Connect the switch at the top of the DBS sub-rack to the external DC power source. You are
recommended to pass the power supply cable via the top of the rack.
2. Ground the DBS sub-rack.
Note: a ground strip is fixed to the backplane and ensures its grounding. The rack and subrack ground
are screwed together, thus no special grounding is required for the rack.
Figure 41 DBS sub-rack ground connection
Earthing must be done very carefully in order to assure good operation of the DBS.
3. Make sure that the fuses are inserted in the fuse-holder. Before changing fuse, make sure that the
switch is set to OFF.

ATTENTION: DO NOT CONNECT THE GROUNDING CABLE TO THE SWITCH
BUT TO THE YELLOW/GREEN TERMINAL BLOCK.

3.5.3 Customer access connections (circuits interfaces)
Considerations
This connection involves the use of:
either direct connectors TNT1 to TNT4, (corresponding to TNT board plug into the chassis) at
the top of the DBS sub-rack, if no distribution frames (cf. § 3.5.3.1 Direct connections to the con-
nectors of the top panel of the DBS chassis.);
or the optional distribution frames at the top of the DBS sub-rack in the standard rack (coaxial
cables for the 75 ohm links, balanced pair cables for the 120 ohm links cf. § 3.5.3.2 Connections
to 75 ohm coaxial distributors and § 3.5.3.3 Connections to 120 ohm distributors).
Note: the provided equipment is already connected and parts of the installation kit.
3.5.3.1 Direct connections to the connectors of the top panel of the DBS chassis.
Note: All connectors are female connectors.
