B-4 Other Precautions

DVD/CD-ROM

Keep the following notes in mind to use the DVD/CD-ROM for the server:

 Press the center of the storage case to remove the DVD/CD-ROM from the case.

 Do not drop the DVD/CD-ROM.

 Do not place anything on the DVD/CD-ROM or bend the DVD/CD-ROM.

 Do not attach any label onto the DVD/CD-ROM.

 Do not touch the signal side (nothing is printed on this side) with your hand.

 Place the DVD/CD-ROM with its printed side upward and gently put it on the tray.

 Do not scratch the DVD/CD-ROM or write anything directly on it with a pencil or ball-point

pen.

 Do not leave the DVD/CD-ROM with foods and drinks, or in a place exposed to cigarette

smoke.

 Do not leave the DVD/CD-ROM 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 DVD/CD-ROM, wipe the DVD/CD-ROM

from its center to edge with a dry soft cloth slowly and gently.

 Use the dedicated cleaner to clean the DVD/CD-ROM. Do not use record spray/cleaner,

benzene, or thinner.

 Keep the DVD/CD-ROM in the dedicated case when not in use.

Tape Media

The following describes data handling with the DAT 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

NEC 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.
