• Key Lock/Drive Power Switch: Performs three functions. The key lock assures
proper seating of the device carrier within the receiving frame, turns power to the
device carrier on and off, and prevents unauthorized removal or installation of the
carrier. For the computer to access data on the DE100i-S disk drive, the key must
be turned counterclockwise to the locked position.
The key can optionally be attached to the locking mechanism as shown in Appen-
dix C.
• Unit ID Number Indicator (Figure 4): Displays the physical address of the
DE100i-S device carrier if the carrier is Installed and Locked in the receiving frame
or if the carrier is Removed from the receiving frame. If the carrier is Installed but
Not Locked in the receiving frame, a "u" will be displayed to indicate an unlocked
condition. The unit ID number is selected by means of the unit ID select switch inside
the receiving frame using a special alignment tool supplied with the DE100i-S.
• Activity Indicator: A small dot next to the Unit ID Number which illuminates to show
when the host computer is accessing the data on the DE100i-S carrier. Depending
on the type of interface, this dot will either flash or glow steadily during communi-
cation with the host computer.
• Device Spin Down/Up Timer: May be disabled by removing Jumper J6 P1-P2
(Figure 5). The timer controls the length of time that the unit number display flashes
during device spin down/up, providing a visual indication of drive activity. Refer to
Figure 11 for switch settings.
