Install Fused Shunt 150-1669-01 at locations J3603 and J3604 to provide circuit protection to

the M+ (+12Vdc) and M- (-12Vdc) inputs to the UC5170 Serial Port Line Driver.

The output of Pin-25 from the Serial Port on the 501-1381 CPU is -5Vdc. There is no output

from Pin-25 on the 501-1899 CPU.

The 501-1381 CPU is not supported in Sun-4/470 serial numbers 136Kxxxx and greater. This

chassis has two 50-pin SCSI-2 connectors on the rear EMI cover.

SNC 1.2 for Solaris 1.1 requires CPU 501-1381-09 or 501-1899-01.4.

The final software release for the Sun 4400 is Solaris 2.4.5.
