2.9.1
Port Link Status Indication (D17 – D22)
The PEX 8624-AA RDK provides up to six green color link status LEDs, D17 to D22, to indicate its port 0, 1, 5, 6,
8 and 9 link states. LED on, off, and three blinking patterns cover all five states of port link status. (See
Table 2-2
for details)
Table 2-2. Port Link Status LED Functions

2.9.2
Fatal Error Indication (D24)
The PEX 8624 provides an output status pin (FATAL_ERR#) which reports the event of a PCI Express fatal error
condition. The RDK connects this output to a red LED (D24) which is lit when a fatal error condition is detected.
Examples of fatal error conditions are data link layer protocol errors, receiver overflow and malformed TLPs. The
PCI Express Base specification provides a complete listing of fatal error conditions. The
PEX 8624-AA Data Book
also provides additional details on the assertion of FATAL_ERR#.
2.9.3
PEX_INTA Interrupt Indication (D23)
The PEX 8624 provides an output status pin (PEX_INTA#) for signaling various programmable events. The RDK
connects this output to a green LED (D23) for this interrupt output. Please refer to the
PEX 8624-AA Data Book
for additional information on the programmable events for PEX_INTA#.
