Maintenance
3Com recommends the following procedures for preventive
maintenance:
Observe the environmental requirements listed in Table 1-6 on
page 1-12. Temperatures outside the recommended range can impair
reliability and cause diskette access errors.
Keep the area around the server clean. Avoid accumulated dust,
especially around the air intake slots.
For Model CS/2600 only:
Handle the software distribution and working diskettes carefully. Always
hold a diskette by its protective cover or by the label area; never touch
the magnetic media, the metal clips at the edges, or the metal disk in the
center.
