3-2.3 Power-On LED Tests
This section describes how to power-on the BTS and verify that the cards in the system come up
properly by viewing the LEDs on the front panel. The purpose of these tests is to verify that the LEDs
come up in the correct state, indicating that the system is operating normally.
When you power-on the BTS, it automatically runs its power on self tests (POST), downloads software to
the TRX cards, then attempts to bring up the cards. While it is bringing up the cards and when it is
finished, the LEDs indicate the state of the each card.
Use the following procedure:
1 Power on the BTS by depressing the power buttons illustrated in Figure 2-8.
2 Verify that the front-panel LEDs flash in the sequence shown in the following figure:
Figure 3-4 LED Locations
The POST tests will be used later. You can ignore them for now.
