•

Enable EPP AIB and Flow Control Crossbar AIB

•

Release reset on EPP AIB and Flow Control Crossbar AIB

If neighboring Scheduler cards are present:

•

Reset EPP AIB and Scheduler AIB

•

Enable EPP AIB and Scheduler AIB

•

Release reset on EPP AIB and Scheduler AIB

•

Restore the Scheduler Control register CRC Action bit if it was set before initializing this Port

Board.

These sequences should complete with only the "ready up" interrupts enabled. When these interrupts

occur (which may be during later parts of the above sequences) then perform the following:

When DS AIB ready up:

•

Inform local processes that the DS is operational

•

Enable all interrupts on DS, except for Transceiver Comma Detect and 8b10b Decoder Comma

Detect which are set every time an idle is received.

When EPP AIB ready up for at least one Scheduler and at least one set of Flow Control Crossbars:

•

Inform local processes that the EPP is operational

•

Enable all interrupts on EPP

•

Set Fault Tolerance Control

•

Enable Port Processor

•

Define 1-in-N Idle Count value

•

Take EPP out of LCS Stop mode

1.8.3

Scheduler Board being added:

•

Wait for voltage ramp-up

•

Suggested:

•

Initialize the OOB satellite FPGA
