Preface
DataDirect Networks EF2800 FC RAID Storage System User Guide (V 1.0) ix
Battery Safety
The battery is user replaceable, please refer to the Battery Replacement
Procedure.
Warning ! There is a danger of explosion if the battery is incorrectly
replaced.
• Dispose of used batteries in accordance with the manufacturer’s
instructions and National regulations.
Laser Safety
Class 1 Laser Product
When the EF2800 is supplied with optical modules they contain a laser
that complies with Laser Class 1, US 21 CFR (J) and EN 60825-1.
If optical modules are to be provided and fitted by the end user, lasers
must comply with the standards listed above.
Rack System Precautions
The following safety requirements must be considered when the unit is
mounted in a rack.
• The rack design should incorporate stabilizing features suitable to
prevent the rack from tipping or being pushed over during
installation or in normal use.
• When loading a rack with the units, fill the rack from the bottom up
and empty from the top down.
• The rack should comply with the airflow requirements detailed in
the technical specification.
• The rack design should take into consideration the maximum
operating ambient temperature for the unit, which is 40°C when
dual cooling modules are fitted.
• The rack should have a safe electrical distribution system. It must
provide overcurrent protection for the unit and must not be
overloaded by the total number of units installed in the rack.

x DataDirect Networks EF2800 FC RAID Storage System User Guide (V 1.0)
Preface
Consideration of the units nameplate rating should be used when
addressing these concerns.
• The electrical distribution system must provide a reliable earth for
each unit and the rack.
• Each power supply in each unit has an earth leakage current of
0.65mA. The design of the electrical distribution system must take
into consideration the total earth leakage current from all the
power supplies in all the units. The rack will require labelling with
“HIGH LEAKAGE CURRENT. Earth connection essential before
connecting supply”.
• The rack when configured with the units must meet the safety
requirements of UL 1950 and IEC 60950.
ESD Precautions
Caution ! It is recommended that you fit and check a suitable anti-static
wrist or ankle strap and observe all conventional ESD precautions when
handling EF2800 plug-in modules and components. Avoid contact with
backplane components and module connectors, etc.
Electrical Surges
A powerful electrical surge (2,000 volts), primarily associated with a
lightning strike, may cause a Storage Manager (SM) to go offline or
restart. You may have to manually put the SM module back online.
Review the event log to determine the SM’s status (see section 7.2 on
page 108) and take the appropriate action based on its status. For
information about restarting an SM, see section 4.3.1 on page 62. For
information about putting an SM online, see section 4.3.4 on page 64.
Tests show that electrical surges up to 2,000 volts coming through the
AC connection will not damage the SM hardware.

Preface
DataDirect Networks EF2800 FC RAID Storage System User Guide (V 1.0) xi
Data Security
• Power down your host computer and all attached peripheral
devices before beginning installation.
• Each enclosure contains up to 16 removable disk drive modules.
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 enclosure is used with modules or blanking plates missing for
more than a few minutes, the enclosure can overheat, causing
power failure and data loss. Such use may also invalidate the
warranty.
• If you remove any drive module, you may lose data.
- 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 completely
foolproof.
Special Tools and Equipment
There are no special tools required but in order to complete the
assembly of some configurations you may need the following:
• Security keys (one of these should be included with your EF2800
enclosure for use with the drive locks).
