2.3 Remote LED connection
To add an optional remote LED, attach a two-pin, 0.1-inch connector to
pins 13 and 14 of the options jumper block.
2.4 Jumpers
You can connect two drives to a daisy-chain cable if both drives meet
the same interface specifications. In a dual-drive configuration, one drive
is designated as the master (drive 0) and the other as the slave (drive 1).
See Figure 3 on page 16 for jumper settings.
If you intend to use either the cable select option or the spindle synchro-
nization option in a dual-drive system, you should determine which of
these options your system supports before continuing. See your com-
puter documentation for details. These options are described in more
detail in Sections 2.5 and 2.6.
2.4.1 Jumper sizes
The jumper blocks use 0.1-inch configuration jumpers. Use Seagate part
number 10562-001 or an equivalent.
Caution. If you try to install a jumper that is not the correct size, you
could damage the jumper and the jumper block pins.
2.4.2 Factory test jumper block (J6)
The pins on this jumper block are used for testing during the manufac-
turing process; do not install jumpers on them.
