Core I/O Connections

The following paragraphs describe the indicators and connections of the rp54xx Core I/O. Core I/O consists of a LAN/SCSI card in slot 1 (lower slot in graphic) and a Guardian Service Processor (GSP) in slot 2 (upper slot in graphic). There are two versions of GSP, revision A and revision B.

Revision A GSP

The following graphic shows the indicators and connectors for the revision A GSP and LAN/SCSI Core I/O boards.

10-Base-T LAN (RJ-45) Connector
GSP LAN.
Green/Red (Upper LED)
Green = GSP Power On.
Flashing Green = LAN Receive.
Red = Guardian Support Processor Test Failed.
Green/Red, (Lower LED)
Green = Link OK.
Flashing Green = LAN Transmit.
Red = Guardian Support Processor Test Failed.
Console/UPS/Remote Connector (D-Type 25-Pin female).
Requires an A5191-63001 “W” adapter cable
10/100 Base-T = Primary LAN (RJ-45) Connection
Path 0/0/0/0
Green/Yellow (Upper LED)
Green = 100 Base-T Mode
Green Blinking = 100 Base-T Receiving
Amber = 10 Base-T Mode
Amber Blinking = 10 Base-T Receiving
Green (Lower LED)
Green = Link OK (10/100 Base-T Mode indicated by LED #6)
Green Blinking = Transmitting
Ultra-2 SCSI Connector (68-Pin VHDCI SCSI)
Path 0/0/1/0
SCSI Mode (Green, Upper LED)
On = Low Voltage Differential (LVD) Mode.
Off = Single Ended Mode.
SCSI Terminator Power (Amber, Lower LED)
On = Terminator power present
Off = Terminator power Not present.

Revision B GSP

The following graphic shows the indicators and connectors for the revision B GSP and LAN/SCSI Core I/O boards.

10/100-Base-T LAN (RJ-45) Connector.
