Configuring the Profile Disk Drives
The Profile disk recorder internal drives can not be used when a RAID unit is
connected. To disable the Profile system’s internal disk drives and enable the RAID
Storage, refer to your Profile User Manual.
Removal of Profile Internal Disk Drives
NOTE: Only qualified service personnel should perform the following procedure.
If you want to use a Profile disk recorder with attached RAID Storage, and are sure
you will not be using that Profile without RAID Storage, you can remove the Profile
system’s internal disk drives for use elsewhere. Two procedures follow, one for the
PDR100 and one for the PDR200.
Removing PDR100 Internal Drives
To remove the internal disk drives from the PDR100, perform the following
procedure:
1. Turn all power to the Profile Off.
NOTE: You should NOT discard any hardware or cables.
2. Refer to your Profile Service Manual to remove the top cover from the Profile
chassis.
3. Refer to your Profile Service Manual to remove the SCSI cable(s). (If you have a
2-channel system there will be a SCSI A cable only. If you have a 4-channel system
there will be both a SCSI A and a SCSI B cable.)
4. Refer to your Profile Service Manual to remove the Hard Disk Carrier Tray from
the Profile chassis.
5. Refer to your Profile Service Manual to remove the hard disk drives from the tray.
(There will be 4 hard disk drives if you have a 2-channel system and 8 hard disk
drives if you have a 4-channel system.)
6. Refer to your Profile Service Manual to reinstall the empty Hard Disk Carrier Tray
into the Profile chassis.
7. Use cable ties to anchor the loose hard disk drive cable(s) to the inner top edge of
the Hard Disk Carrier Tray.
8. Attach jack screws (2 each, P/N 214-4689-00) to the bus terminator (P/N
011-0170-00), both of which came with your RAID Storage chassis. Refer to ➊ in
the following illustration.
