the switch for more than four seconds to force the system to power down. The POWER
switch on the secondary PCI module will be unlit and will not respond until a failure in the
primary PCI module causes the secondary PCI module to assume primary functionality.
6 CD-ROM drive
Used for reading data from CD-ROMs.
Although there are two CD-ROM drives, only the one on the active primary PCI module can
be used (the module with the lit POWER Switch LED).

Slots for adding hard disks. On a tower model, they are called Slots 1, 2, and 3 from the
bottom. On a rack-mount model, they are called Slots 1, 2, and 3 from the left. Slots of the
same number are mirrored between the groups 1 and 2.
8 DUMP switch
A switch for outputting a memory image from the kernel to a file.
9 DISK LED (green/amber)
An LED on the hard disk. Blinks in green while the hard disk is accessed and turns amber
when operating in simplex mode. If one of the mirrored hard disks fails, the failed disk’s LED
turns green and the other disk’s LED turns amber.
