Comment
Firmware check
Flickering indicates command being
received from IOT
Flickering indicates status information being
received from DADF
Lit indicates that MEM_RDY signal is active
Lit indicates that reset line from IOT is active
Not lit when CPU firmware operating cor-
rectly
Comment
Indicates +3.3 VDC is present on the PWBA
Page Sync signal from POST to MEMORY, lit
when signal is active
Output Page Sync signal from CMM1 (blue),
Lit when signal is active.
Output Page Sync signal from CMM2
(green), Lit when signal is active.
