2.4.2 Alternate capacity jumper
This jumper lowers the drive capacity by setting the default translation to
4.092 cylinders. Some BIOSs that only auto-detect may require this
jumper. Place a jumper on pins 1 and 2 of the J5 options jumper block
to enable this option. When installing this jumper, you may need third-
party partitioning software to achieve full capacity of the drive.
2.4.3 Cable-select option
Computers that use cable-select determine the master and slave drives
by selecting or deselecting pin 28, CSEL, on the interface bus. Master
and slave drives are determined by their physical position on the cable.
• The drive plugged into the I/O connector that carries the CSEL signal
is the master.
• The drive plugged into the I/O connector that does not carry the CSEL
signal is the slave.
To configure the drives for computers that use cable select:
• Install jumpers on pins 5 and 6 and pins 7 and 8 as shown in
Figure 4 on page 20.
• Connect the drives to the cable as shown in Figure 5 on page 22.
2.4.4 Remote LED connection
You can connect a remote LED to pins 3(–) and 4(+) of the options jumper
block (J5). Do not install a shunt jumper on these pins.
Because the jumper block uses a 0.1-inch connector, you may need to
replace the current connector. Use Seagate connector part number
10562-001 or an equivalent.
