Chapter 1: Introduction Control Panel The SuperServer 8060'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 SC860 is a 4U rackmount, WTX form factor chassis. Its I/O shield provides seven motherboard expansion slots, one COM port (the other is internal), a parallel port, two USB ports, PS/2 mouse and keyboard ports, a video port and an Ethernet port. (See Figure 1-1.) Figure 1-1.
I/O Shield Cooling System The SC860 chassis has an innovative cooling design that includes four 9- cm hot-plug system cooling (intake) fans and two 9-cm hot-plug exhaust fans. All system fans (located between the drive bays and the mother- board) operate continuously. If one fails, an alarm is activated and the RPM of the remaining fans increase to compensate and maintain sufficient air- flow. A CPU air shroud is also included to concentrate cooling air around the processors, which generate the most heat. 1-3
