2) Execute Fdisk and create a 4GB partition on the Hard Drive.
3) Remove the bootable floppy and put the NT 4.0 Server CD in the Drive.

11) Delete the 4GB partition you created (with Fdisk).
12) Install NT 4.0 Server into the 4GB of unpartitioned space now recognized
by NT 4.0 Server.
13) Choose NTFS as your file system.
14) Follow all screen prompts until NT 4.0 Server asks to be rebooted.

Front Panel - Power & Reset Switches
The HDIT-850D-36M features 2 switches mounted centrally on the front panel.
To power up the HDIT-850D-36M, press hold the power switch. The Power LED
(green) will then glow indicating power is being supplied to the unit.
NOTE: If the unit does not power up, check the power connections
and the main power switch on the back panel below the power
supply.
The second switch is the system reset switch. Press the switch to reset the HDIT-
850D-36M, (See Figure 1).

Rear Panel - Power Supply
Situated on the back of the HDIT-850D-36M is an Auto-Switching 115/
230VAC power supply, (See Figure 5). The system main power switch is located
just beneath the power supply’s cooling fan. Turn off the main power switch and
remove the power cord from the HDIT-850D-36M before servicing or moving the
unit.

The HDIT-850D-36M is equipped with two removable 36GB Ultra Wide SCSI hard
drives, (See Figures 1 & 2). TAG has configured the removable drives with the follow-
ing SCSI ID’s: The left drive, is SCSI ID #0 and the right drive, is SCSI ID # 1. Depend-
ing on the configuration, the drives may not be hot-swappable. If the HDIT-850D-
36M is configured to mirror the two drives, then the drives may NOT be removed
while the unit is powered up. If the HDIT-850D-36M is configured to utilize just the
two drives, then the system drive (holding the O/S) can NOT be removed while the
system is running (hot). The other drive may be removed while the system is running.
NOTE: If you are unsure of the system configuration, power down the unit
to remove either drive.
To remove either drive, insert the hard drive module key and turn the keylock
clockwise to the unlocked position. Grab the handle and slide the drive out. Insert
the replacement drive into the HDIT-850D-36M and turn the keylock counter-
clockwise to the locked position.
