Installation manual

The 501-1439 Backplane terminates J2/P2, Row C, Pins 75 and 96 with a 40.2 Ohm resistor and a
47pf capacitor.
The 501-1598 and 501-1832 Backplanes terminate J2/P2, Row C, Pins 75 and 96 with a 200 Ohm
resistor. Termination is jumper selectable.
The Sun 4400 CPU is not supported in the 501-1439 Backplane.
The function of the backplane jumpers is shown below.

501-1498 and 501-1597 16-Slot Backplanes
The Sun P2 bus connects cardcage Slots 1 through 7 to each other, cardcage Slots 11 and 12 to each
other, and cardcage Slots 13, 14, and 15 to each other.
In addition to the Sun P2 bus and the VMEbus, the 16-slot backplane private internal bus connects
Slots 1, 2, and 3 as shown below.
J101 Row A Connects to J201 Row A and J301 Row A
J101 Row B Connects to J201 Row B and J301 Row B
J101 Row C Connects to J201 Row C and J301 Row C
J102 Row B Connects to J202 Row B and J302 Row B
J1/P1 Rows A, B, and C on Slots 1, 2, and 3 are not connected to the VMEbus. Boards that use the
VMEbus cannot be used in Slots 1, 2, or 3. J2/P2, Row B, is connected between Slots 1 through 7.
The 501-1498 Backplane must be 501-1498-02 or greater when used with the Sun 4400 CPU.
The function of the backplane jumpers is shown below.
