3.5 General Electrical
•
Consideration should be given to the connection of the equipment to the mains power and the effect that any
possible overloading of circuits might have on over current protection and supply wiring. Appropriate consideration of
equipment nameplate ratings of all connected equipment should be used when addressing this concern.
•
Reliable earthing of rack-mounted equipment should be maintained in addition to any grounding conductor provided
in the power cord. Particular attention should be given to supply connections other than direct connections to the
branch circuit (e.g. use of power strips).
3.6 General Environment
•
Be sure to maintain freedom of air movement around equipment to ensure safe operation.
•
Installation of the equipment in enclosed racks is not recommended due to possibility of restricted air flow.
•
Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the
equipment is not compromised.
•
The equipment is designed to operate to specification in an ambient temperature of +0°C to +40°C (+35°F to +104°F),
however, normal room temperature is recommended to ensure long term operation of the equipment.
•
If equipment is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment
in an environment compatible with the maximum ambient temperature (Tma) of +40°C (+104°F).
3.7 Gigabit Ethernet Ports
The input ports are auto MDI-MDIx and intended to be connected to a network distribution switch using straight through wired
Cat5e or better quality cable. The rear panel Management Interface port allows connection to a notebook or desktop PC for
managing and configuring the system. The port may be connected to directly, or in the case of a headend with many devices to
manage, may be connected to a management network (recommended) or the distribution switch containing the video stream
content. It is possible to set up virtual ports for a VLAN. Connections should be made with Cat5e or better network cables.
The GigE management port is auto MDI-MDIx and may be connected to a switch or router with a straight through wired cable.
