Message "aaaa" received from a Network Card (NT8D04). The possible messages are:

1. PLL UNLOCK EVENT. The Network card lost synch with the system clock. 2. MSG FROM SHELF x: XPEC ERROR 0001. This error is usually self correcting. If may indicate a double timeslot problem or invalid call teardown. 3. TN READ UNBLOCKED: CNT=x. A number of SSD messages were sent to the PS card but not acknowledged. In order to prevent the locking of the message path, the Network card assumed the message was received. 4. Any of the following three messages:

XNET POLLING FAILURE ON PORT x RSIG LINK LOST ON PORT #x - REINITIALIZED R71 DISASTER; CANNOT ALIGN TRANSCEIVERS.

These messages indicate that the Controller is not responding to the Network card polling messages.

Ignore if message occur when clocks are switched. If it occurs periodically, switch the clocks. If it occurs often, replace Network card or clocks

Random XMI000 messages may be generated if excessive Electrostatic Discharges (ESD) are allowed to enter the system. These messages may be safely ignored. Refer to General Maintenance Information (553-3001-500) for ESD avoidance practices.

1. a If message occurs rarely, ignore it.

b. If it occurs often, replace the Controller.

2. a. If message occurs rarely, ignore it.

b. If it occurs often, replace the PS or Network card.

3. a. Check cabling between Controller and Network.

In X11 Release 15 and 16, "FRw APx SQy TPz" is output before the text, where "w" is the loop number. This data is not output in X11 Release 17 and later. Messages without text indicate that the Network or Controller card have requested software download.
