4.4 Setting Up on the Bench
Before installing the base station in the on-site cabinets or racks, you need
to set it up on the bench. You can then verify that it is operating correctly,
and tune it if necessary. You can also customize its configuration for the
installation it is destined for and verify that the configuration is correct. An
important aspect of that configuration is the base station’s IP address. The
base station comes with a default IP address but needs to be given the IP
address required for its position in the TaitNet digital network.
Important
Make sure that the RF output is connected to a suitable
attenuator or dummy load.
Confirming Operation
To ensure that the TB9100 is working correctly before site installation, you
may want to apply power to check for proper operation.
Applying Power
1. Before turning the TB9100 base station on, carry out the following
tasks:
■
check that the PMU is turned off – ensure that the AC and DC
module power switches are both set to ‘Off ’ (refer to
Figure 5.5
on page 66 )
■
12V PA only: check that the battery supply lead is disconnected
(refer to “Replacing the Power Amplifier” on page 80 )
■
remove the front panel (refer to “Preliminary Disassembly” on
page 75 )
■
check that all looms and cables at the front and rear of the base
station are fitted correctly
■
check that all connectors are secure
■
refit the front panel – ensure that it is fitted correctly so that the
fans will operate if needed (refer to
“Final Reassembly” on
page 88 )
2. Apply power by turning on the PMU, or by connecting the battery
supply lead to the 12V PA.
3. Check that the base station powers up correctly:
■
check that the cooling fans in the front panel turn on in the
correct order after power-up: the PMU fan will run first, followed
by the PA fan and then the reciter fan; each fan will run for about
five seconds and then switch off (note that the PMU fan is not
fitted to a 12 V PA base station)
■
check that the LEDs on the control panel come on after about five
seconds, and then go off (refer to
“Control Panel” on page 61 )
■
at this point you can safely press the speaker and microphone
channel button and check that they are operating correctly
