HP SureStore CD-ROM Server/Tower/Expansion - Installation and Hardware Connection

Customizing your Tower
  • If all the drives needed at this time are already installed, proceed to "Steps to Connect the Towers."
  • If you will be installing additional drives or extending your HP J3278A Server/Tower 7Plus, then use the optional sections below as needed, before proceeding.
    • "Extending HP J3278A Server/Tower 7Plus"
    • "Adding an HP SureStore CD-ROM Drive"
    • "Adding an Non-HP CD-ROM Drive"
Extending HP J3278A Server/Tower 7Plus
HP C2988A SureStore CD-ROM Tower
This accessory most conveniently provides the additional bays for extending beyond the seven drives in the HP J3278A SureStore CD-ROM Server/Tower 7Plus. This tower includes a SCSI cable to connect the two HP SureStore CD-ROM towers and an external active HP SCSI terminator to be installed on a rear SCSI connector. SCSI IDs are set automatically on HP CD-ROM drives only (not on CD-ROM drives from other vendors), based on their position in the HP SureStore CD-ROM tower. The top most position on this accessory tower is ID 0 on the second SCSI bus, and the lowest position is ID 6 on the second SCSI bus. All 14 drives are read by the server module located in the HP J3278A SureStore CD-ROM server/tower.
To add drives to the 7-bay HP SureStore CD-ROM tower, you can use the sections:
  • "Adding an HP SureStore CD-ROM Drive"
  • "Adding an Non-HP CD-ROM Drive"
Consult the User’s Manual accompanying the 7-bay tower for its specific installation instructions. Complete the SCSI cable connection to the HP J3278A SureStore CD-ROM server/tower, the SCSI termination connection, and the power cord connection as directed in that manual. The "Steps to Connect the Towers" include the steps needed to start up both HP SureStore CD-ROM towers.
  note:
To install the 7-bay tower after the HP SureStore CD-ROM server/tower has been installed, you must switch off power to the HP SureStore CD-ROM server/tower before installing the 7-bay tower. After installing the 7-bay tower, follow the "Steps to Connect the Towers" to restart the HP SureStore CD-ROM server/tower.
Other SCSI-2 devices
As an alternative to the HP 7-bay tower described above, you can attach a chain of up to four SCSI-2 stand-alone (external) drives to the HP J3278A SureStore CD-ROM server/tower, using its rear SCSI-2 connector. The connector is 50-pin female high-density micro-D.
  caution:
SCSI Chain Limits:
* No more than four SCSI devices chained from the server tower.
* Cable lengths between devices limited to one meter.
* Total external cabling limited to four meters.
Industry-standard SCSI-2 cables and terminators are available in different lengths and with different connector types; obtain cables that match the connectors on your drives. The HP SCSI products in the table below may, or may not, match your drives. The server/tower will manage the second SCSI bus composed of the added drives; you must set the SCSI IDs of your drives for that bus, and terminate the chain.

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 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.
Optional jumpers
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:
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 (R) system from a CD-ROM drive in an HP SureStore 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.
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.)
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.
Installation steps
  1. Place the tower on an even surface, like a table or work bench. Do not use an uneven surface like a carpeted floor. Make sure the tower is turned off.
  2. Use the key to unlock the front cover. The cover is locked when the key index points to the right. The cover is unlocked when the key index points up.
  3. Place both of your hands on the top two corners of the front cover and carefully pull it towards you. The cover will still be attached at the bottom.
  4. You can now remove the front cover by lifting it up, making sure that the flange at the bottom of the cover has cleared the opening of the tower casing. Set the front cover aside.
  5. With the front cover off, you can remove a filler panel covering the bay. Hook your finger behind the right or left end and nudge it out slightly. Repeat on the other side. Repeat on each side alternately until the panel pops off.
    With the front cover off, you can remove a CD-ROM drive module by placing both hands on the two handles on both sides. Pull the module using even pressure on both handles.
  6. You can install a CD-ROM module by aligning the rails with the two grooves provided in each bay of the tower. Slide the module in by holding the two handles on both sides and pushing firmly until it is seated properly. Just before it stops, you should feel the module inserting into its socket.
    You can install a filler panel to cover an empty bay. Align the studs on back of the filler panel with the grooves on the sides of the tower. Align the pegs with the holes in the metal at both sides of the front of the tower. Gently push in the left or right side of the panel, then push in the other side, until it pops into place. No screws are needed to secure the panel.
  7. When you are finished, replace the front cover by first hooking the flange of the cover into the bottom of the tower case. Close the cover by pushing it towards the main body of the tower. Be sure to lock the cover using the key.
  8. You can now turn on power to the tower.
Adding a Non-HP CD-ROM drive
You need mounting rails
SCSI-2 compatible CD-ROM drives can be installed into the towers. You need to add side rails to the drive to fit it into the tower bays, using HP C2998A Mounting Hardware for Non-HP Drives. The mounting hardware includes four M3 by 0.5 inch screws and four standard screws. The hardware is compatible with HP J3276A, J3277A, and J3278A SureStore CD-ROM server/towers and the 7-bay HP C2988A SureStore CD-ROM tower.
  note:
IDE and EIDE CD-ROM drives are not supported.
Installation steps
  1. Make sure that the towers are turned off.
  2. Unpack the mounting hardware.
  3. Check to see that your CD-ROM drive is SCSI-2 compatible.
  4. Set the SCSI ID jumpers on your CD-ROM drive. (Refer to the device’s installation manual. Some SCSI drives may contain special termination instructions.)
      note:
    Set the SCSI ID (using jumpers) to the number etched in the metal at the side of each bay (inside the tower’s front cover), or choose the bay etched with the number matching the ID.
  5. You have received two sets of four screws. You must identify which set fits with the lowest holes on each side of the drive.
      warning:
    Use only the lowest holes to attach the mounting hardware.
  6. Position the mounting hardware along the drive as shown in the illustration above. Align the holes and insert the four screws. The power cord and SCSI ribbon cable should be located toward the bottom of the drive.
  7. Plug in the power cord and the SCSI ribbon cable.
  8. Perform all the steps in "Installing the Drive Module" section.
Troubleshooting
  • When plugging in the assembly, the CD-ROM hits one of the other devices or the tower frame,
    -or-
    the assembly does not slide in all the way.
    • The assembly is upside down.
    • The CD-ROM drive above or below is upside down.
    • One device does not have standard CD-ROM dimensions.
    • The mounting hardware is upside down or attached to the wrong holes.
Steps to connect the Towers
Before you begin
  • Verify with your network administrator that a 10Base-T (Ethernet) or 100Base-TX (Fast Ethernet) network connection is ready for the HP SureStore CD-ROM server/tower. Locate the twisted-pair network cable (with an RJ-45 connector).
  • Verify that the HP SureStore CD-ROM server/tower’s power is off.
  • Verify that the power supply input voltage is set according to the power standards in the country of use; set the voltage switch on the rear of the tower to 115 volts or 230 volts. Also verify that the power cord is appropriate for the country of use.
  caution:
The SCSI bus may be damaged if you connect or disconnect any units when the power is on.
  • If you are extending the HP J3278A SureStore CD-ROM server/tower 7Plus (using its rear SCSI connector), you must complete all cable and termination connections on the towers, and on any stand-alone drives used, before you apply power to the towers or drives. Apply power to the 7-bay tower, or other standalone drives, before you apply power to the HP J3278A SureStore CD-ROM server/tower.
Optional rack mounting
You can mount the HP SureStore CD-ROM server/tower in a rack using the HP C2982A CD-ROM Tower Rackmount Kit.
  1. Attach the power cord to the rear of the tower and to the power line source. Do not turn on power yet.
      note:
    If you are also installing the 7-bay HP C2988A SureStore CD-ROM Tower (to the HP J3278A SureStore CD-ROM server/tower), install its power cord now then switch on it's power.
  2. Attach the network cable to the RJ-45 connector on the rear of the HP SureStore CD-ROM server/tower.
  3. On the front of the HP SureStore CD-ROM server/tower, switch on the power. Verify that:
    • The ON/BUSY indicator lights on the HP CD-ROM drives go on.
    • The 4 indicator lights on the server module flash during a power-on self-test.
    • When the Status indicator (yellow) stops flashing and remains off, the server/tower is ready for use. Depending on the number of drives in use, this may take a few seconds to five minutes.
    • The server auto-negotiates the link speed (10 or 100 megabits per second) and duplex setting (full or half) with other devices on the network.
  4. Press the Stop/Eject button to access the tray of the topmost CD-ROM drive, place a compact disc into the tray, and press Stop/Eject again to close it. Verify:
    • The drive’s ON/BUSY indicator light turns off and the DISC light goes on. If either one flashes continuously, then either the disc is not standard or there is a problem with the drive.
    • The server’s CD indicator light (green) goes on. If it does not, then verify your connections and cycle power (switch power off and wait 10 seconds and then switch power on again) to the HP SureStore CD-ROM server/tower.
      Repeat step 4 for all drives (including the 7-bay tower if used).
How to use HP SureStore CD-ROM drive
  • Tray door: Press Stop/Eject button to open door. Insert CD into drawer. Press Stop/Eject button to close door.
  • Stop/Eject button: Push to eject CD.
  • Emergency Eject button (recessed): If the automatic Stop/Eject button does not work, switch off power. Insert a paper clip or other thin rigid object in this hole to press the recessed button to eject the CD.
  • ON/BUSY indicator: On (yellow) when power is switched on. Flashing continuously when CD is inserted and being accessed. Off when CD is inserted and not being accessed.
  • DISC indicator: On (green) when power is on and CD is inserted. Off if no CD is inserted.
Tray loading and operation
  1. While the drive is powered up, push the Stop/Eject button. The tray drawer will slide out in 2 to 3 seconds.
  2. Lay the bare CD into the depression in the tray, label side up.
  3. Press the Stop/Eject button again, and the tray will slide shut within 2 to 3 seconds.
      note:
    We recommend you use the Stop/Eject button to close the tray in a smooth and secure manner. Closing the tray by pressing the front of the drawer by hand is not recommended.
Care of CD-ROM discs
Check your CDs periodically to determine if they need cleaning.
If the CD is dusty, you can use a commercially available dust removal spray to blow off dust particles. After removing the dust particles, you can wipe the CD using a clean, soft cotton cloth. Use a straight-line motion, wiping from the center out. Do not wipe the CD in a circular motion.
Correct procedure for cleaning a disc
If a CD becomes dirty or soiled with grease or other contaminants not removable by wiping, you can clean it with a CD-ROM disc cleaner available at most computer dealers. Follow the directions packaged with the cleaner.
  note:
Keeping your CD in its original case or in the CD-ROM drive at all times will prevent it from becoming dirty or damaged.
