7. Slide the system I/O baseboard assembly all the way to the rear until it is removed from chassis. CAUTION: The I/O baseboard assembly is large. Be careful when lifting it out of the server chassis. Figure 3-17 I/O Baseboard Assembly Removal Replacing the I/O Baseboard Assembly NOTE: The I/O baseboard assembly replacement procedure assumes that you are reinstalling the assembly that was previously removed from a configured server. To replace the I/O baseboard assembly, follow these steps: 1. Ensure that all fan modules are removed from the chassis before sliding in the I/O baseboard assembly or the fans and the I/O baseboard can be damaged. 2. Align the I/O baseboard assembly rails with the chassis slots and slide the assembly into the chassis until it stops against the midplane riser board socket. To engage the I/O baseboard with the midplane riser board correctly, ensure the I/O baseboard locking lever is in the up position. CAUTION: The I/O baseboard assembly is large. Use care when sliding it into the server chassis. 3. With the I/O baseboard flush against the midplane riser board socket, push down firmly on the locking lever until the I/O baseboard plugs all the way into the midplane riser board socket and the locking lever clicks into place on the chassis wall (Figure 3-16). 4. Replace the three chassis fan units. See "Replacing a Hot-Swappable Fan Unit" (page 69). 5. Plug all external cabling into the ports at the rear of the chassis. 6. Plug the internal SCSI cables into the HBA board in PCI slot 1. 7. Replace the top cover. See "Replacing the Top Cover" (page 66). Installing Additional Components 71

chassis.
Figure 3-17 I/O Baseboard Assembly Removal
Replacing the I/O Baseboard Assembly
NOTE:
The I/O baseboard assembly replacement procedure assumes that you are reinstalling
the assembly that was previously removed from a configured server.
To replace the I/O baseboard assembly, follow these steps:
1.
Ensure that all fan modules are removed from the chassis before sliding in the I/O baseboard
assembly or the fans and the I/O baseboard can be damaged.
2.
Align the I/O baseboard assembly rails with the chassis slots and slide the assembly into the
chassis until it stops against the midplane riser board socket. To engage the I/O baseboard
with the midplane riser board correctly, ensure the I/O baseboard locking lever is in the up
position.
CAUTION:
The I/O baseboard assembly is large. Use care when sliding it into the server
chassis.
3.
With the I/O baseboard flush against the midplane riser board socket, push down firmly on
the locking lever until the I/O baseboard plugs all the way into the midplane riser board
socket and the locking lever clicks into place on the chassis wall (
Figure 3-16
).
4.
Replace the three chassis fan units. See
“Replacing a Hot-Swappable Fan Unit” (page 69)
.
5.
Plug all external cabling into the ports at the rear of the chassis.
6.
Plug the internal SCSI cables into the HBA board in PCI slot 1.
7.
Replace the top cover. See
