Connectors

The ATCA-9305 circuit board has various connectors and headers (see the figures beginning
on page 2-3), summarized as follows:

J1:

This 14-pin JTAG header is used for debugging CN5860 processor 2. See

Table 3-7

J3-J6:

These 240-pin sockets are installed for the CN5860 processor 1 DDR2 SDRAM memory.

J9:

This 14-pin configuration header allows selection of boot device, and MPC8548 configura-
tion for the configuration SROM. See

Fig. 2-6

J11-J14:

These 240-pin sockets are installed for the CN5860 processor 2 DDR2 SDRAM memory.

J15:

This 14-pin JTAG header is used for debugging CN5860 processor 1. See

Table 3-7

J23:

The 80-pin Zone 2 connector provides 1 GB and 10 GB Ethernet access to the backplane, see

Table 8-2

J30-J31:

The 80-pin Zone 3 connectors route PCIe and XAUI (10G) to the optional RTM. See

Table 8-3

and

Table 8-4

for pin assignments.

J33:

The 24-pin Zone 3 connector routes the reset, Hot Swap, MPC8548 console, power, and
IPMC I

C to the optional RTM, see

Table 8-5

JP1:

This is the 10-pin programming header for the IPMP, CPLD, and SPI 10G (1-4) devices, see

Table 7-51

P1:

This 14-pin RJ45 connector with LEDs routes the Three-speed Ethernet Controller (TSEC1)
between the MPC8548 and the front panel. See

Table 6-4

for pin assignments.

P2:

This 16-pin JTAG debug header accesses the MPC8548 processor, see

Table 4-7

P3:

This 14-pin RJ45 connector with LEDs routes Ethernet (FP1) between the switch and the
front panel, see

Table 6-4

for pin assignments.

P4:

The 5-pin vertical mini-B USB provides the IPMP EIA-232 console debug, see

Table 7-52

P5, P6:

These 5-pin vertical mini-B USBs are the CN5860 console and for factory debug use only.

P7:

This 5-pin mini-B USB is the console serial port for the MPC8548 management processor,
see

Table 4-8

P10:

The 30-pin Zone 1 connector routes IPMB to the backplane, see

Table 8-1
