Infrastructure
Planning recommendations
For a potential expansion of the network at a later point of time, space for additional
equipment racks should be reserved on site.
The equipment racks may be freestanding or they may be placed against the wall with
the rear or with either side. If multiple equipment racks of the same type are used in the
operation room, these may also be positioned next to each other. It is not possible to
stack equipment racks.
The following requirements must be met for being able to operate the network element
as intended:
| Free space of at least 700 mm for service purposes:
– on the front of the equipment rack
– on the top of the equipment rack
| Maximum distance between the equipment racks (from five carriers) of 50 mm.
| The space above the equipment rack (no superstructures) depends on the bending
radius of the antenna cable used.
Figure 4.1 shows the space required when setting up the DIB-500 R4.1.
