3. Align the connectors with respect to the front line of the cable tray as
indicated with the installation instructions for the corresponding unit
(refer to Figure 28). The cable length between connector and cable tray
depends on the unit and interface (for detailed information, refer to the
user manual of the corresponding unit).
4. Place the front cable ties in order to allow the cables to be bent neatly to
the earthing bar in the front part of the cable tray.
5. Install the rear cable ties. The positions of these cable ties depend on
the cable type (refer to
6. Secure each cable loosely (e.g. using cable ties). It should still be possi-
ble to move cables back and forwards. The signal cables have to be
arranged (and fixed) on the cable tray so as not to block the access to
adjacent units in the subrack.
End of instruction
Attention to temperature range! Attention to temperature range. Risk of equipment damage!
Blocking the airflow might lead to overheating inside the subrack.
→ Cables should be positioned so as not to block the airflow into the
subrack.
The user manuals of the units provide the layout of the cables used for the
interfaces of each unit. For most units with traffic interfaces one cable con-
nects all the interfaces of the unit.
For details on the installation of signal cables refer to the units user manuals.
The fan unit features the following signal interfaces for connection:
• Alarm input interfaces,
• Alarm output interfaces.
The cables for these interfaces are not generally connected but implemented
as required. For your convenience it is a good practice to install these cables
now together with the signal cables on the cable tray.
For details of the alarm interfaces, refer to the section
page 66).
Cable tray and cables are now ready for the installation of the FOX subrack.
The cables terminated on the FOX are connected to their connection points
in accordance with the documentation of the installation and the local
requirements.
