Diagnostics

When the AGILE 5250 ALLY either powers up or is Reset (Mode A from the front panel, or !AGILE!=POR; via the data stream), it performs a set of diagnostics on the internal hardware. These diagnostics include a ROM checksum test to ensure that the ROM has not been corrupted, a RAM test, and an internal loop test. (The internal loop tests the 5250 ALLY twinax communication controller chip, and it is permissible to be connected to the network during this operation.)

External Loop Test (Mode E)

An external loop test is also available. This diagnostic will test the transmit and receive circuits of the 5250 ALLY. This test is available as part of continuous testing that can be initiated with Mode E from the front panel of the 5250 ALLY.

NOTE: to perform this test, the twinax “T” must be attached to the 5250 ALLY twinax port, and both cables must be disconnected from the “T” connector so that it only serves as a terminator for the test.

Failure to disconnect can cause permanent damage to the equipment.

The full set of diagnostics performed is listed below:

1.ROM checksum

2.RAM

3-6. Internal Loop (Data, Address, End-of-Message)

7-9. DMA Loop (Data, Address, End-of-Message)

A-C. Optional External Loop (Data, Address, End-of-Message)

During testing, the 5250 ALLY LED will display each of these numerals or letters as it performs each test. If an error is detected, the numeral or letter of the test in which an error occurred will remain flashing on the LED. If this occurs, contact AGILE technical support as indicated later in this chapter. To end continuous testing of the 5250 ALLY, the unit must be powered down.
