NexLog Recorder User Manual v2.2.0

In short, if you are concerned about malicious users making a purposeful
effort to gain
unauthorized access to your data
, then the only real protection
is to place the unit in a secure location.
Cable lengths.
For analog signals, such as POTS lines and radio receiver
outputs, cable lengths are not likely to be an issue. An adequate level can be
obtained hundreds of feet from the signal source. The unit has
programmable adjustments for low or high signal levels. That being said,
shorter cable lengths will create less signal attenuation and pick-up less
noise than longer cable lengths. For tapping digital PBX telephones and
T1/E1 circuits, maximum cable lengths are extremely important, and can be
different for different makes & models of telephone systems. Contact
Eventide technical support for digital-tap cable length information for your
particular digital phone system or T1/E1 circuits.
Particulates.
The archive drives and, to a lesser extent, the fans and hard
drives, can be damaged by smoke and dust. If you find dust build up on the
surfaces or the fans being clogged, consider changing the location.
Power dropouts or surges.
The unit should be protected from power dropouts
and surges. The chosen location should have line power available that is not
on the same circuit as equipment that draws a large current on start-up,
such as electric motors or compressors or banks of fluorescent lights. Line
voltage fluctuations, brown-outs, and power outages can result in loss of
data and damage to the unit. An Uninterruptible Power Supply is required to
mitigate these problems. For a list of approved UPS units, see
Section
2.4.6. Connecting AC Power and UPS (Uninterruptible Power Supply)
Spilled liquids.
Liquids spilled on the unit can damage it. The location should
not encourage people to place coffee cups on the unit, for instance.
Vibration and Shock.
Vibrating or physically shocking the unit while the hard
drives are operating could damage the hard drives. The location should not
be subject to vibration or jolting while the unit is operating.
2.4.4. Mounting Options
As normally provided, the unit can be mounted on any flat, non-sloping surface
that can bear its weight. It can be rack mounted if the rack has a shelf to
support it, and the supplied mounting ears can be attached to the rack with the
rack screws provided, in order to prevent casual removal. The unit must not be
mounted solely with the mounting ears and rack screws!
If no rack shelf is available, a rack-slide rail install kit, which includes slide
rails, rear slide supports, brackets, and mounting hardware, can be ordered:
