2.8. Grounding Checks
The product must only be connected to a power source that has a
safety electrical earth connection.
CAUTION:
If more than one product is fitted in a rack, the earth
connection to the rack is even more important, because the rack will
then have a high “EARTH LEAKAGE CURRENT” (“TOUCH CUR-
RENT”).
The earth connection to the rack must be checked before switching
on, by an electrical engineer who is qualified to the appropriate lo-
cal and National standards to perform the check.
2.9. Data Security
✦
Power down your host computer and all attached peripheral
devices before beginning installation.
✦
Each enclosure contains up to 12 removable disk drive mod-
ules. Disk units are fragile. Handle them with care, and keep
them away from strong magnetic fields.
✦
All the supplied plug-in modules and blanking plates must be
in place for the air to flow correctly around the enclosure and
also to complete the internal circuitry.
✦
If the subsystem is used with modules or blanking plates miss-
ing for more than a few minutes, the enclosure can overheat,
causing power failure and data loss. Such use may also invali-
date the warranty.
✦
If you remove a drive module, replace it immediately. If it is
faulty, replace it with a drive module of the same type and
capacity.
✦
Ensure that all disk drives are removed from the enclosure
before attempting to manhandle or move the rack installation.
✦
Do not abandon your backup routines. No system is com-
pletely foolproof.
CAUTION:
Prior to removing the PSU from the Power Supply
Mounting Cage in the enclosure: Please disconnect the power from
the power supply, by either the mains switch (where present) or by
physically removing the power source, to ensure your system has
warning of an imminent power shutdown.
