Adding an HP SureStore CD-ROM Drive

These drives, fully modular and self-configuring, can be installed
in any of the seven drive bays in the HP J3276A, J3277A, and
J3278A server/towers, and in the HP C2988A SureStore CD-
ROM Tower. Drives have attached side rails, used to slide the
drive into the bays in these towers. No cables are needed.
If you are installing an additional HP CD-ROM drive module or
you are removing or replacing an existing one, all you need is the
front cover key. No tools are required.
Three of the four jumpers on the back of the drive should never
need changing when installing into an HP server/tower. One
jumper is an option you can set. All are described below:
Prty (Parity). Leave this set to on. The parity check provided
by the on setting enhances the reliability of the SCSI bus.
Term (Termination). Leave termination disabled—off.
Termination should not be used in a tower.
Block. Leave this off (in 2048-block read mode). You cannot
boot a UNIX system from a CD-ROM drive in an HP CD-ROM
server/tower.
Eject (Lock). The factory-default setting is off, that is, the
Eject button is enabled. If you want to prevent others from
removing the CD inserted in your drive (such as in an open
workgroup setting) you can activate this Eject Lock feature by
setting this jumper to on. Then it is impossible to eject a CD
inserted in the drive by pressing the Eject button. It is possible
to eject the CD only by use of the Emergency Eject button; see
page 2-12.
Changing Jumper Settings
1. Place the drive module flat on a firm surface with the back of
the drive and the attached connector card facing you.
2. Find the four black jumpers on the right side of the attached
connector card, to the left of the four colored power wires.
• To set a jumper to on, install it over both pins assigned to
that jumper.
• To set a jumper to off, install it over one pin only.
(If a jumper is removed, it is set to off.)
