Installing the Receiving Frame
NOTES: For SCSI Ultra160 operation, the DE300 requires Ultra160 chassis and cabling.
These newly-designed Ultra160 68-pin DE300 (with blower) carriers are inter-
changeable with other Ultra160 68-pin DE300 (with blower) receiving frames and
older Ultra160 68-pin DE300 receiving frames (without blowers).
Older Ultra160 68-pin DE300 carriers are NOT designed for use with the newer
Ultra160 68-pin DE300 (with blower) receiving frames (overheating may occur if
there is inefficient air flow within the enclosure).
The drive should be installed into the carrier before installing the receiving frame into the
mounting bay of a computer or expansion chassis.
NOTE: Use a #2 Phillips screwdriver during this procedure.
1. Turn OFF power to the computer.
2. Open the computer system according to the manufacturer’s instructions. If neces-
sary, temporarily remove any expansion boards that may make installation difficult.
3. To select the DE300 unit ID remotely through the computer system or external ex-
pansion chassis, the appropriate cable from the system must be connected to the
option pins (1-8 on connectors J3A1, J3B1, J3C1) on the rear of the receiving frame
as shown in Figure 7.
