CD/DVD Discs
Keep the following notes in mind to use the disc for the server:
„
Press the center of the storage case to remove the disc from the case.
„
Do not drop the disc.
„
Do not place anything on the disc or bend the disc.
„
Do not attach any label onto the disc.
„
Do not touch the signal side (nothing is printed on this side) with your hand.
„
Place the disc with its printed side upward and gently put it on the tray.
„
Do not scratch the disc or write anything directly on it with a pencil or ball-point pen.
„
Do not leave the disc with foods and drinks, or in a place exposed to cigarette smoke.
„
Do not leave the disc in a high-temperature place (e.g., place exposed to direct sunlight or close to a heater).
„
When dust or fingerprints are attached on the disc, wipe the disc from its center to edge with a dry soft cloth slowly and
gently.
„
Use the disc cleaner to clean the disc. Do not use record spray/cleaner, benzene, or thinner.
„
Keep the disc in a disc case when not in use.
Tape Media
The following describes data handling with the DAT, DLT, or AIT optionally available for the server.
„
Saving your valuable data
When you save your valuable data or programs into the cartridge tape, you should save them into two cartridge tapes
to make the primary and secondary tapes.
This enables you to restore your data from one tape when the other makes a read error, as well as to protect your
valuable data and programs from loss.
„
Three-generation data management
Bull recommends that you should employ three-generation data management for data storage.
Three-generation data management uses three cartridge tapes: A, B, and C. You save data to tape A on the first day,
tape B on the second day, tape C on the third day, tape A on the forth day, and so on. That is, you save data into
cartridge tapes cyclically from tape A through C.
This enables you, for example, to use tape B to restore the data when tape C makes a read error. Also when both
tapes B and C make a read error, you can restore your valuable data by using the data stored in tape A.
Keyboard
The keyboard is a device to instruct you computer by entering alphanumeric characters or symbols.
IMPORTANT:
„
Do not pour any liquid such as water or put anything into the keyboard. Doing so may cause a
failure of the keyboard.
„
The keyboard provided with the server is designed for adjustment of an angle. Adjust the
keyboard angle at which the keyboard is easy to operate. The adjustment assists in reducing
strain on your shoulders, arms, and fingers.
