These drives, fully modular and self-configuring, can be installed in any of the seven drive bays in the HP J3276A, J3277A, and J3278A SureStore CD-ROM 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.
YOU NEED ONLY A FRONT COVER KEY
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 to be changed when installing into an HP SureStore CD-ROM server/tower. One jumper is an option you can set. All are described below:
Leave this set to on. The parity check provided by the on setting enhances the reliability of the SCSI bus.
Leave termination disabled (off). Termination should not be used in a tower.
Leave this off (in 2048-block read mode). You cannot boot a UNIX (R) system from a CD-ROM drive in an HP SureStore CD-ROM server/tower.
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.
CHANGING JUMPER SETTINGS
Place the drive module flat on a firm surface with the back of the drive and the attached connector card facing you.
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.)
INSTALLING THE DRIVE MODULE
While following the procedure in "Installation Steps," take the precautions listed below:
caution:Make sure that the towers are turned off.
Do not attempt to move or carry a tower without hooking the cover at the bottom and locking the front cover lock.
When replacing the front cover of the tower, make sure that the flange on the bottom of the cover is engaged in the cut-out opening of the main body. Locking the cover without properly aligning the flange can damage the tower case or cover. The drives can be damaged if moved in this condition.
Do not push the drive module in by pushing on the bezel of the CD-ROM drive itself. This may result in damage to the drive’s door, or you might snap the plastic bezel of the drive. Always use the metal handles provided with the drive.
Make sure you align the two side rails of the CD-ROM drive module with the grooves in the walls of the tower. If the drive module is not in the grooves, the tower will not function properly.
Do not force the drive module into the tower or you may damage the circuit board. Firm pressure should be adequate.
Do not use tools of any kind. If the drive module will not install properly, remove it and call HP for support.
Replace the front cover of the tower by hooking it at the bottom first. Then close the cover at the top. Lock it.
