7.2.3 Installing a Secondary Hard Drive
The secondary 9.1 GByte hard drive option for the Ultra 5 system ships with a
special bracket and a new hard drive cable that has connectors for the primary
(master) drive and the secondary (slave) drive. The secondary hard drive and its
bracket replace the diskette drive and its bracket. Use the following procedure to
install the optional secondary hard drive in place of the diskette drive.
1. Power off the system, remove the system cover, and attach an antistatic wrist strap
as described in Chapter 5.
2. Disconnect all cables from the rear of the diskette drive.
3. Loosen, but do not remove the three screws that hold the diskette drive bracket to
the chassis (
FIGURE 7-6
).
4. Remove the diskette drive bracket from the chassis by sliding it back and lifting
it free of the three screws. Set the bracket aside.
5. Remove any PCI card from PCI slot 2.
See Section 8.4.1 “Removing a PCI Card” on page 8-9.
6. Disconnect the diskette drive cable from the motherboard and set the cable aside.
7. Disconnect the existing hard drive cable from the rear of the master hard drive
and from motherboard connector J15.
8. Place the new secondary hard drive into the secondary hard drive bracket and
install the four screws that hold the drive to the bracket.
Note –
Before installing the hard drive into the system, verify that the drive’s back-
panel mode-select jumper is set to CS.
9. Place the new hard drive bracket and hard drive on top of the power supply.
10. Connect the new hard drive cable’s “MOTHERBOARD” connector to
motherboard connector J15.
11. Connect the new hard drive cable’s “MASTER” connector to the EIDE connector
on the back of the primary (master) hard drive.
12. Connect the new hard drive cable’s “SLAVE” connector to the EIDE connector on
the rear of the new secondary (slave) hard drive.
