BOARD STRUCTURE
HDD (Hard Disk Drive)
The combined capacity of the HDD's is 80 GB (40 GB x2) for image storage. They
can store up to approximately 3,000 copy images, based on the ITU-T No. 4 Chart.
The ASIC on the controller handles data by dividing each 32-bit word into 16-bit
units and writes the high-end bits to one hard disk and the low-end bits to the other
hard disk. This effectively reduces the write speed by 50% because each half of
each 32-bit word is saved simultaneously. Because the data is divided between the
two hard disks, replacing only one of the hard disks will cause errors. Therefore,
both disks must always be replaced together.

Note the following important points regarding HDD replacement:
• Both HDD's must always be replaced together as one set.
• Replacing the HDD loses all document server documents, and user stamps.
• When the HDD is replaced, the default user stamps must be re-installed, so use
SP5853 to copy these files from the controller firmware onto the hard disk.
• The "Scan to Email" addresses are also lost by HDD replacement. However,
addresses can be backed up with Smart Net Monitor.
• Print fonts must also be re-entered after HDD replacement.
