SYSTEM INSTALLATION
BEFORE YOU MAKE CONNECTIONS
Before you make connections to the unit, be sure to position or mount the unit for
proper operation, making sure the following conditions are met:
NOTE: Connect short term storage devices, such as USB ThumbDrives, USB
Hard Disk Drives, USB CD-RWs, etc.,
only after the DigiMux is
successfully powered up.
• Short term storage devices that are connected to and recognized by the DigiMux
during the power-up sequence are then used as part of its internal storage system.
Recorded video is then written to those devices. Thus, removing these short term
storage devices creates a disruption in the storage database. If you have a short
term storage device hooked up to the DigiMux, remove it before you power up the
unit.
• You can place the unit on a flat surface, or rack mount the unit using the supplied
rack mounting ears. To rack mount the unit, you must supply adequate support
for the back part of the unit for safe, effective operation. Check with your rack
mount manufacturer for additional materials required to mount the back part of
the unit to the rack, if required.
NOTE: Make sure that rack-mounted units are installed to permit enough air flow for
safe operation. The maximum allowable temperature for rack-mounted units
is 40° C. Avoid uneven loading or mechanical instability when rack mounting
units. Check product label for power supply requirements to assure that no
overloading of supply circuits or overcurrent protection occurs. Mains
grounding must be reliable and uncompromised by any connections.
• Air should freely circulate around the unit, especially on the left side, where the air
ducts are located.
NOTE: Do not hinder or block air flow on the left side of the unit.
NOTE: The use of an Uninterruptible Power Supply (UPS) unit is highly
recommended. UPS units are used to protect critical computing systems
from power fluctuations that may cause loss of data or damage to the system.
• Temperature extremes affect the ability of your DigiMux to function properly. If
exposed to extreme temperatures, allow the unit to come to room temperature
prior to installation.
• A default IP address is assigned to your unit. When you connect the unit to the
Internet, this address must be changed in order to avoid possible conflicts with
