Notes

1. The Sun 4200 CPU requires EPROM 3.0 or greater when more than two 16MB ECC memory boards are installed.
2. 501-1092 or 501-1117 BackpIanes: Install a single memory board in Slot 6 with a 220/270 Terminator, 120-1613-01, installed at location U1203. Remove the terminator when expansion memory boards are installed in Slots 2, 3, 4, and 5.
3. 501-1439 or 501-1498 Backplanes: Install a 220/270 Terminator 120-1613-01, at location U1203 on the memory board in Slot 1. If placement results in memory boards on both sides of the CPU, remove the terminator at location U1411 on the Sun 3400 CPU, and install terminators on the memory boards in Slots 1 and 7.
4. The 8MB memory board must be >=501-1102-11 to use with the Sun 3400CPU, the FPA, and the FPA+.
5. The 501-1451 32MB board >=501-1451-03 to use with the 501-1576 6MB memory board.
6. Remove jumpers P10, P11, P12, and P13 from the 501-1598 and 501-1832 backplanes when the Sun 3400 board set is installed.
