CD/DVD-ROM
Keep the following notes in mind to use the CD/DVD-ROM for the server:
„
Press the center of the storage case to remove the CD/DVD-ROM from the case.
„
Do not drop the CD/DVD-ROM.
„
Do not place anything on the CD/DVD-ROM or bend the CD/DVD-ROM.
„
Do not attach any label onto the CD/DVD-ROM.
„
Do not touch the signal side (nothing is printed on this side) with your hand.
„
Place the CD/DVD-ROM with its printed side upward and gently put it on the tray.
„
Do not scratch the CD/DVD-ROM or write anything directly on it with a pencil or ball-
point pen.
„
Do not leave the CD/DVD-ROM with foods and drinks, or in a place exposed to cigarette
smoke.
„
Do not leave the CD/DVD-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 CD/DVD-ROM, wipe the CD/DVD-ROM
from its center to edge with a dry soft cloth slowly and gently.
„
Use the CD/DVD cleaner to clean the CD/DVD-ROM. Do not use record spray/cleaner,
benzene, or thinner.
„
Keep the CD/DVD-ROM in a CD/DVD-ROM 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
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.
