DIAGNOSTICS AND TROUBLESHOOTING

Built-in diagnostic capabilities for the 3F00-01 and 3F55-01 include:

• Power-up diagnostics, which are run every time the 3F00-01/3F55-01

is brought online.

• Front panel status LEDs

• Local and remote loopback tests.

• Temperature sensors.

5.1 POWER-UP TESTS

The power-up diagnostics test processors, memory, and other critical

components on all ATX modules. Power-up diagnostics also verify proper

interaction between all the modules.

Each of the interface modules is tested in order (from top to bottom of the

ATX). LEDs on the front panel indicate progress of the power-up

diagnostics sequence and the status of each module as determined by the

power-up diagnostics.

The 3F00-01 and 3F55-01 LED power-up sequence is described in detail

in Chapter 2, Connecting to the Network.

When the power-up diagnostics are completed (this takes between 1 and 2

minutes after power is applied, depending on the conﬁguration of the

ATX), the appropriate traps (alarms or event messages) are generated and

sent to the NMS.

If a 3F00-01 or 3F55-01 fails a critical test, it is automatically disabled.

After completion of the power-up diagnostics, the 3F00-01/3F55-01

status LEDs should operate as shown in Table 5-1 and Table 5-2.
