Removable-media drive replacement

The S3400 Message Servers use different removable-media devices as follows:

• Messaging Application Server (MAS): A Compact Disc (CD) Read Only Memory (ROM) drive is used primarily to load system programs and updates. This is a read-only device; data is backed up on the MSS's DVD.
• Message Storage Server (MSS): A Digital Versatile Disc (DVD) Random Access Memory (RAM) drive provides read/writable backup information for the system. The same DVD-RAM drive is used in both the MSS-S (standard) and MSS-H (high-availability) configurations. However, the internal cabling varies slightly between the different machines due to the hard-disk drive arrangement.

Replacing a CD or DVD drive

To replace the removable-media drive in a message server:

1. Verify that the replacement equipment is on site and appears to be in usable condition, with no obvious shipping damage.
2. Verify that the replacement equipment is the same type of device as the one you are replacing (either a CD or DVD as appropriate).
3. Remove the drive cage.
4. Replace the removable-media drive (see the section below).
5. Reinstall the drive cage and return the system to service.
6. Verify operation of the new drive.

Replace the removable-media drive

To replace the CD or DVD drive:

1. Remove the 4 screws that secure the faulty drive to the drive cage (2 per side). See Removing or replacing a CD or DVD drive.

Note: Observe which screw comes from which hole. Each screw must be reinserted into the same hole it came from so that the CD or DVD drive will be correctly offset about 1 inch from the front of the machine.

2. Slide the old drive out of the drive cage. Set it aside.
3. Set up the replacement drive to be a master or slave on the IDE bus as follows:
   • CD-ROM: Always set up a CD to be a slave. See CD or DVD jumper settings.
   1. Locate the mode select connector (the 6-pin connector next to the IDE signal connector).
   2. Move the jumper to the center 2 pins labeled "Slave."
   • DVD-RAM: Set the jumpers as noted. See CD or DVD jumper settings.
   1. Locate the mode select connector (the 6-pin connector next to the IDE signal connector).
   2. Move the jumper to connect the appropriate 2 pins as follows:
      • MSS-S: Move the jumper to the center 2 pins labeled "Slave."
      • MSS-H: Move the jumper to the 2 end pins labeled "Master."
4. Insert the new drive into the drive cage.
5. Reattach the 4 screws to secure it in place.

Note: Be sure to insert the screws into the same holes that you removed them from, so that the CD or DVD drive is offset about 1 inch from the front of the machine.

6. Reinstall the drive cage and return the system to service.

Verify new drive operation

To verify that a new CD-ROM drive is working:

1. Insert a CD into the new drive.
2. Verify that the system can access the disc.

Note: If the replacement CD-ROM is a different model of drive, you may be prompted to load new drivers.

To verify that a new DVD-RAM drive is working correctly:

1. Insert a writable DVD disc into the new drive.
2. Verify that the system can read from and write to the new drive by doing a backup.
   • From the Messaging Administration main menu, select Utilities > Backup and Restore > Backup.
   • To verify your results, select "View Attributes of Backup Media". See Backing up system files for more information.
