The onSafe rack offers easy video connection
and distribution in environments with high density of cameras,
without congestion in the transmission of video flows. It
consists on a 6U height cabinet (for a 19’’
racks) with 14 slots (with internal power supply) or 16
slots (with external power supply).
The onSafe switch card (optional) is
inserted in the first slot and includes:
-
3 Giga Ethernet ports (10/100/1000
BaseT): copper Ethernet on the 3 ports, optionally additional
fiber Ethernet support in the third port, for Backbone
connection and racks interconnection. Redundant topologies
(i.e. ring) are supported using Spanning Tree. Trunking
is supported using the first and the second ports, providing
redundancy and load balance.
-
3 Fast Ethernet Ports (100 BaseT)
(Only one in case of onSafe/RACKS with 16 slots). They
may be used for the connection of video massive storage
systems (onSafe SVG), video processing applications,
operator's workstations, etc.
The onSafe switch card performs Ethernet
switching between the different cards inserted in the
slots, and provides a link to the backbone for all aggregated
traffic, reducing cabling overhead and improving overall
reliability.
The rest of the slots are used to hold
the onSafe MPEGx (and onSafe MPEG2) encoder or decoder
blade cards, with or without Video Analytics plug-in cards.
Each codec card has 4 or 8 video inputs, and therefore
the maximum capacity is 104 cameras (14 slots) or 120
cameras (16 slots) per rack.
The power supply can be either internal
(high reliability power supply) or external. The external
power supply can power several onSafe racks and supports
redundant high availability configurations.
In a typical high density installation
the different onSafe racks can be interconnected to a
ring topology, and connect to the backbone with a single
or redundant Gigabit link. The video recording systems
can be attached directly to the onSafe racks, optimizing
bandwidth occupancy and avoiding traffic congestion of
the network.
