Chapter 1: Introduction Control Panel The SuperServer 6040's detailed control panel provides comprehensive system monitoring and control. LEDs indicate network activity, power sup- ply failure, fan failure, fan status, SCSI drive activity and failure and SCA backplane overheat conditions. The control panel also includes a main power button, a system reset button and an alarm reset switch. I/O Shield The SC840 is a 4U rackmount chassis. Its I/O shield provides seven moth- erboard expansion slots, two COM ports, a parallel port, two USB ports, PS/ 2 mouse and keyboard ports, and an Ethernet port. (See Figure 1-1.) Sound holes: not present on the 6040 Figure 1-1.
I/O Shield Cooling System The SC840 chassis has an innovative cooling design that includes four 9- cm hot-plug system cooling (intake) fans and one 9-cm hot-plug exhaust fan. All system fans operate continuously to provide optimal cooling for add on cards, memory and processors. If one fails, an alarm is activated and the RPM of the remaining fans increase to compensate and maintain suffi- cient airflow. 1-3
