3.2.4 Power-On LED Tests
This section describes how to power-on the Micro BTS and verify that the cards in
the system come up properly by viewing the Light Emitting Diodes (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 Micro BTS, it automatically runs its power on self tests
(POST), downloads software to the E1 or T1 cards, and 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 each card.
Use the following procedure to power on the chassis and verify the LEDs:
1 Turn the power to the chassis on by simultaneously switching on two power
supplies. The power supply switches are shown in Figure 2-13 and
Figure 2-16. This will share the start up load across the power supplies.
2 Verify that the front-panel LEDs flash in the sequence shown in Figure 3-4.
