Kontron CG2300 Installation And Maintenance Manual page 32

The SSI signal cable must be disconnected in order to perform tasks such as replacing the front panel board or replacing the
server board.
The SSI front panel board signal cable connects the front panel board connector (J1) with the baseboard (SSI_FRONT_PANEL,
J1A2).
For the location of the baseboard SSI front panel board connector, see Figure 12 in this cable section (E).
For the location of the SSI power control signal connector on the FPB, see Figure 39 in Section 5.2.14.
Serial Cable
In order to remove the server board, you need to disconnect the serial cable, which is part of the multifunction front panel board
power and signal cable, from the baseboard. Since this cable is part of the multifunction front panel board cable, you also need
to disconnect it to replace the fan control board, or to work with the HDD LEDs.
As part of the multifunction front panel board cable, along with the HDD LED cable and COM2, the serial cable interconnects the
front panel board (FPB) with the fan control board, the baseboard, and the HDD LEDs. For the location of the multifunction cable
connector on the FPB (J1A1), see Figure 39 in Section 5.2.14. For the location of the serial connector on the baseboard
(SERIAL_A), see Figure 12 in this section (E).
Front Panel Board USB Cable
The USB cable has to be disconnected in order to perform tasks such as replacing the front panel board or replacing the server
board.
The front panel board USB cable connects the baseboard to the FPB to provide USB 2.0 signals.
For the location of the baseboard USB connector (USB-5-6, J1K1), see Figure 12 in this section (E). For the location of the USB
connector on the FPB (J4), see Figure 39 in Section 5.2.14.
(E3) Other Baseboard Signal Cables
IPMB/Fan Cable
I 2 C
The IPMB cable (aka Fan I C) has to be disconnected in order to perform tasks such as replacing the server board or replacing the
2
fan control board.
The IPMB cable connects the baseboard with the fan control board (FCB) to provide fan control signals. For the location of the
IPMB connector (J1D4) on the baseboard, see Figure 12 in Chapter 4. For the FCB I
5.2.17.
Before you can disconnect the IPMB/Fan I
on the FCB: the support cross bar, the baseboard power cables, the cable bundle bracket/fan cage. For instructions, see (D),
(E1), and (G) in Chapter 4.
HSBP I 2 C Cable
The HSBP I 2 C cable has to be disconnected in order to perform tasks such as replacing the SAS backplane, the front panel board,
or the server board.
The HSBP I 2 C cable connects the HDD HSBP (hot-swap backplane) to the baseboard and the front panel board to provide HDD
LED signal control on the disk drive carriers and on the system front panel. For the location of the HSBP I
HDD backplane, see Figure 16 in Section 5.2.20. For the location of the HSBP I
board, see Figure 39 in Section5.2.14. For the location of the HSBP I
Chapter 4.
Before you can disconnect the HSBP I
active HDD carriers from the drive bay, and the HSBP backplane and air duct from the SAS HDD drive bay assembly. For
instructions, see (I) and (H) in Chapter 4.
