Twinax Addressing
After power-on hardware diagnostics and during twinax initialization, the
twinax port is monitored to check the 5250 ALLY twinax configuration
against the actual port configuration. Before the 5250 ALLY will begin
communication on the twinax address, it monitors the line to ensure that
the selected address is not being used by another device on the twinax
network. If the address is already used, the 5250 ALLY will not use the
address, but will flag the configuration error to the user. After twinax
initialization, during normal operation, the configured twinax address is
continually monitored by the 5250 ALLY.
Error Codes
Decimal Point On
If the 5250 ALLY front panel LED decimal point light is On, the system is
polling the unit on the configured address.
Decimal Point Off
If the decimal point is Off, the system is not polling that address. If the
System is not polling that address, either the unit is not connected
properly, or the System is not configured to have a device on that address.
Check the connections, and if the error persists, configure the System to
accept a device on that address.
Decimal Point Slow Flash
If the decimal point is flashing On and Off in half-second intervals, the
unit is in slow poll mode.
Decimal Point Fast Flash
If the decimal point is flashing On and Off in quarter-second intervals, the
units twinax address is in collision with another device on the twinax line.
The address must be changed to one that is not being used by another
device.
Digital Display Slow Flash
If the digit on the 5250 ALLY front panel LED is flashing at half-second
intervals, the 5250 ALLY is holding data for the printer. During small
print jobs, the flashing may not be apparent to the user, but it will be
noticeable during large jobs that the printer cannot process immediately.
Digital Display Fast Flash
If the digit on the 5250 ALLY front panel LED is flashing at quarter-
second intervals, there is a problem at the printer; probably, the printer is
either off line or out of paper.
