Indicator Panel

The indicator panel is attached to the front panel and contains the power lamp, hard disk drive
busy lamp, and suspend button. The indicator panel electrically attaches to the system board
through connector J11 (suspend connector), J14 (hard disk drive busy lamp
connector), and J16 (power lamp connector).

POWER SUPPLY

The power supply is mounted inside the system unit. It supplies power to the system board, op-
tion boards, diskette drives, hard disks, keyboard, and mouse. The power supply is connected to
the system board through connector J6. A fan inside the power supply provides proper ventilation
for the system. The power supply in the desktop supplies 145W of power. The minitower power
supply provides 200W. Power requirements and specifications for both power supplies are pro-
vided in Appendix C.
