1-6 System Overview
J – DEU (tower-based system) Each bay contains one 3.5-inch disk drive (SCSI ID: from left
to right 0, 1, 2, 3, 8, 9, A, B). Each drive has three status
LEDs. Refer to Table 1-2 for information on disk drive status
LEDs.
K – Power LED When green, power is present in system. When off, power is
