Before you can disconnect the HSBP I
the front panel board: the support cross bar, the power cable bundles in the cable bracket, and the cable bundle bracket/fan
cage assembly. For instructions, see (D), (E1), and (G) in Chapter 4.
(E4) HSBP Cables
The HSBP cables have to be disconnected from the baseboard in order to perform tasks such as installing a hardware RAID
controller or replacing the server board or power distribution board.
The HSBP cables have to be disconnected from the HSBP board on the SAS drive bay assembly to replace the PDB or to remove
or replace the HSBP board.
The hot-swap backplane at the back of the SAS HDD drive bay assembly has the following cables connected:
» SAS HDD Backplane board power cable that provides power from the PDB to the HSBP and up to six SAS HDDs
For the location of the power connector (J11) on the HSBP, see Figure 16 in (H) in Chapter 4. The other end of this cable
is soldered onto the PDB.
» SAS-1 (HDD 0-3) cable that connects the HSBP board to the SAS_0-3 connector on the baseboard or to an optional
hardware RAID controller board
For the location of the SAS-1 connector (MINISAS0, J1) on the HSBP, see Figure 16 in (H) in Chapter 4. For the location
of the SAS_0-3 connector (J1H3) on the baseboard, see Figure 12 in this section (E).
For the location of the SAS-1 connector on a hardware RAID controller card, see Figure 30 in Section 5.2.7 "Installing a
Hardware RAID Controller".
» SAS-2 (HDD 4-5) cable that connects the HSBP board to the SAS_4-7 connector on the baseboard or to an optional
hardware RAID controller board
For the location of the SAS-2 connector (MINISAS1, J3) on the HSBP, see Figure 16 in (H) in Chapter 4. For the location
of the SAS_4-7 connector (J1H3) on the baseboard, see Figure 12 in this section (E).
For the location of the SAS-1 connector on a hardware RAID controller card, see Figure 30 in Section 5.2.7 "Installing a
Hardware RAID Controller".
Before you can disconnect the SAS-1 and SAS-2 cables from the baseboard, you need to remove the left riser card assembly. For
instructions, see (B1) in Chapter 4.
Before you can disconnect the HSBP SAS-1 and SAS-2 cables and the HSBP power cable from the HSBP board, you must first
remove the front bezel, the 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 this chapter.
(E5) Fan Control Board Cables
The fan control board cables have to be disconnected in order to perform tasks such as replacing the front panel board (FPB),
removing or replacing the fan control board (FCB), or replacing the power distribution board (PDB).
The fan control board has the following cables:
» Fan Control Board PWR/SIG cable, which is part of the FPB multifunction connection that coordinates signals to the
front panel
For the location of the FCB PWR/SIG connector (J1A1) on the FCB, see Figure 43 in Section 5.2.17.
» Fan I C cable, which connects the baseboard and the fan control board to provide fan control signals
2
NOTE: This cable, also known as the IPMB cable, is covered in (E3) in this section (E).
» Fan (Fans 1-2), Fan (Fans 3-4), Fan (Fans 5-6) cables, which each connect the FCB with a fan pair in the fan cage.
For the location of the three fan pair connectors (J3A1, J6A1, J9A1) on the FCB, see Figure 43 in Section 5.2.17.
These cables are connected mechanically on the fan pairs in the fan cage.
