Cabling the IDE Carrier Frame
This section describes the cabling of the IDE carrier frame to the system. Follow these steps to
cable your carrier frame.
1. If necessary, remove the floppy housing from the rear of the chassis, refer to Floppy Housing
Removal and Installation on page 98.
2. Connect a power cable to the backplane power connector (PWR1, PWR2, PWR3, or PWR4).
Each connector provides two ground connections plus a +5V and a +12V output. The nominal
wire gauge should be 18, however wire gauges of 16 to 28 can be used for a connection. All
backplane power headers have the same pin-out and can be used interchangeably.
If there is a previously installed power cable with a free connector, it may be used instead of
installing a new one. No more than two drives should be powered by each connector.
3. Connect the other end of the power cable to the power connector on the back of the carrier
frame. The connectors are keyed to prevent misconnection.
4. Connect the signal cable to the appropriate signal connector header on the backplane. See the
following figure and table for locations and appropriate signal connector/drive bay use.
5. Connect the other end of the signal cable to the carrier frame signal connector (JP11).
6. Connect the IDE drive cable to the backplane connector IDE A or IDE B, depending upon the
domain setting of the drive being installed.
Connector Configuration Domain
PSIG1 Primary Master A domain (upper drive)
PSIG2 Slave A domain (upper drive)
PSIG3 Primary Master B domain (lower drive)
PSIG4 Slave B domain (lower drive)
