✓ The equipment rack must be connected to the grounding system.
✓ Appropriate antenna cables of the required lengths must be available.
✓ The toggle switches must be set to the "Off" position ("downward" switch position).
Carry out the following steps:
Cable-specific tools and process steps
The required tools and process steps depend on the antenna cable used and the
related connector.
Cable damage
If cables are routed over sharp edges or in bending radiuses too small for the cables,
the cables may be damaged.
➔ Never route cables over sharp edges and always maintain to the bending radius.
Risk of damage from electrostatic discharge (ESD)
The base station can be damaged if antennas are connected or disconnected during
the switched-on state. The GPS antenna connection is particularly sensitive to electro-
static discharge (ESD).
➔ Ensure that the base station is switched off before connecting or disconnecting
antennas.
➔ Connect the required antennas on the upper side of the equipment rack, refer to
Figure 5.22 on page 119.
The following options are available:
| Connect the GPS antenna:
– to the optional GPS protector (recommended),
– directly to the corresponding connector.
| TETRA antenna(s): Directly connected to corresponding connector/connectors.
✓ The antennas have thus been connected.
