Chapter 1: Working Inside the System
The components shown in Figure 1-10 are:
1. SCSI-B connector on the baseboard
2. Rear foam cover
3. Foam tab
4. SCSI-B cable (fit along recess in foam cover)
5. External SCSI-B connection
6. SCSI knockout cover
System Fans
The SGI 1400 server contains eight removable chassis fans that cool the boards and
removable media drives. These chassis fans connect to the front panel board and are
enclosed in a removable foam assembly. The three integrated power supply fan(s)
provide more cooling and airflow.
Removing the System Fan Assembly
Use the following steps and Figure 1-11 to remove the system fan assembly:
1. Observe the safety and ESD precautions at the beginning this chapter.
2. Remove the access cover.
3. Remove the foam cover from the front subchassis by pulling it straight out.
4. For better access to the individual fan cables on the front panel board, carefully
rotate the right edge of the foam fan assembly outward into the opening where the
foam cover was.
