Axiom Pilot CU Substitution Information

The following table contains the current actively supported part numbers.

Axiom R4 & R5 Pilot CU Substitution
Part Number	Common Name	Version on FRU¹	Supported On	Valid Substitution for²	Additional Notes
1450-00268-32	A1811E R5.4	R5.4.0	Ax600 5.4.0 and higher	1450-00268-3x at R5.4 1450-00314-00 at R5.4	Axioms below R5.4 require a double Pilot replacement. See Document 1609199.1, Pillar Axiom: How to Perform a Double Pilot Replacement in R5. Same hardware as the 1450-00268-30/-31, but with R5.4 .0 image. The video connector is DVI-D. See the referenced article for details on using display.
1450-00314-00	A1811 R5.4	R5.4.0	Ax600 5.4.0 and higher	1450-00268-3x at R5.4	Axioms below R5.4 require a double Pilot replacement. See Document 1609199.1, Pillar Axiom: How to Perform a Double Pilot Replacement in R5. This Pilot CU is the same hardware as 1450-00259-3x but with the R5.4 image. The video connector is DVI-D. See the referenced article for details on using display.
1450-00259-3x	A1811 R4.2	R4.2.0	Ax600 R4.2.0 to R4.6.xx	Any R4.2.0 to 4.6.xx Pilot	This is the ONLY Pilot FRU that should be used for Pilot CU replacements on R4.2 or higher³ The video connector is DVI-D. See the referenced article for details on using display.

The following table is for historical reference only:

The Axiom 300 and 500 are no longer supported.
Part Number 1450-00268-30/31 can no longer ordered.
Axiom software versions R1.x, R2.x or R3.x are no longer supported.

Historical Axiom Pilot CU Parts
Part Number	Common Name	Version on FRU¹	Supported On	Valid Substitution for²	Additional Notes
1450-00268-30-31	A1811 E Enhanced Pilot	5.2.0	Ax500, Ax600 5.2.0 and higher	1450-00268-32 A1811E at R5.4	This Pilot CU is no longer available in FRU spares. The video connector is DVI-D. See the referenced article for details on using display.
1450-00179-3x	DC Pilot	R2.4.2	Ax300, Ax500, Ax600 R2.4.2 - R4.6.x	Any R2.4.2 to 4.6.xx Pilot except A1811E	Cannot be used as a replacement in an R5.x Axiom. Recommended for R4.0 or R4.1 Axioms The DC Pilot is the only version that has an on/off switch on the back. It has nothing to do with the input current type requirement. Black metal faceplate.
1450-00164-2x	Intel 2Gb	R2.4.2	Ax300, Ax500, Ax600 R2.4.2 - R4.6.x	Any R2.4.2 to 4.6.xx Pilot except A1811E	Cannot be used as a replacement in an R5.x Axiom. The Intel Pilot is physically much longer than any other Pilot and requires a longer serial and pilot to pilot ethernet cable. The faceplate is black metal with a blue power LED.
1450-00170-0x	MSI 9249 2Mb⁴	R1.7.6	Ax300, Ax500, Ax600 R1.7.6 or higher,	Any R2.4.2 to 4.6.xx Pilot except A1811E	Cannot be used as a replacement in an R5.x Axiom. Only valid substitution for R1.7.6 to R2.4.1 All MSI pilots have a gray membrane front panel.
1450-00106-0x	MSI 9149 512 Mb^4,5	R1.7.6	Ax300, Ax500, Ax600 R1.7.6 or higher,	Any R2.4.2 to 4.6.xx Pilot except A1811E

¹The "Software on Pilot FRU" is the lowest revision of Axiom software that will support this Pilot model, except as noted in the notes column.

²Although you may encounter older Pilot CUs on a system, one of the following four should always be used as a replacement:

1450-00179-3x DC Pilot for Axioms running R4.0 or R4.1.
1450-00259-3x Distributed Computing A1811 requires R4.2.x to R4.6.x.
1450-00268-32 Distributed Computing A1811E requires R5.4 or higher.
1450-00314-00 Distributed Computing A1811 requires R5.4 or higher.

³In the unlikelihood that an R4.0 or R4.1 Axiom with a Pilot issue is encountered, 1450-00179-3x is the recommended replacement part.

⁴The MSI Pilot CUs are imaged to R 1.7.6 and are the only Pilot CUs that may be used to replace a Pilot CU on a system below R2.4.2. The MSI should never be used to replace a Pilot CU on any R5.x system--it will very likely crash the system. The MSI may also be used to replace a Pilot CU on any release up to R4.x, but only if no other Pilot CU is available. The Axiom 1.x release used separate IP networks for the PMI. The 172.30.81.xx network was used for the Pilot to Pilot ethernet. The 172.30.80.xx network is used for Pilot to Slammer and Slammer to Slammer communications. Release 2.4.2 binds the two Pilot ethernets together and uses Spanning Tree to avoid ethernet frames from repeating until the Pilot or Slammer crashes. All Axiom releases up to and including R4.x are able to detect the older network and temporarily bring up a 172.30.81.xx network to image the new Pilot CU. R5.x does not have this capability, so any new MSI placed in an R5.x system will become pilot1 and will assume it is the active pilot, with potentially disastrous results.

⁵Some models of the MSI Pilot were shipped with only 512 Mbyte memory. These all should have been upgraded to 2 Gb memory as part of the R1.x to R2.x upgrade, however the part number may not have been updated as the memory was upgraded. If you encounter one of the MSI Pilot CUs that does not have 2 Gb memory, contact a product expert and Engineering for assistance.

Axiom systems with older Pilot CUs, including the old DC, Intel, and MSI can be upgraded to R5.x without first replacing the Pilot CUs as long as all software prerequisites are met. The older Pilot CUs may fail on the upgrade, typically because the grub loader is not updated, and it cannot boot the Oracle Linux kernel properly. This is not recoverable in the field--just replace the Pilot CU with one that is supported on the R5 software.
