5.4. Switches
VR-N100U’s architecture allows the networked security appliance to be a completely non-evasive system. For the
Backchannel (LAN2), a dedicated switch is utilized to enable up to 16 network enabled cameras to be managed by VR-
N100U. Using a dedicated high-quality Unmanaged Layer 2 24-Port 10/100 Mbit Fast Ethernet, VR-N100U is capable of
supporting 30 fps for each individual camera. However, we have discovered that some switches offer very poor performance.
Therefore, we have provided a few recommended high-quality Unmanaged Switches:
LinkSys EF3124 24-Port Switch
LinkSys EF4124 24-Port Switch
LinkSys SR224 24-Port Switch
LinkSys SR2024 24-Port Switch
Below is an example of how the backchannel of VR-N100U should be configured. As you can see, only the network cameras
are attached to the switch along with LAN2 of VR-N100U. For further information, refer to section 2.4.5 Setting Up the
Backchannel.
NOTE1: Maximum configuration requires 17 ports (16 cameras and 1 for VR-N100U), thus we recommend high-quality 24-
port Unmanaged Layer 2 Fast Ethernet switches for each VR-N100U.
NOTE2: High-quality 24-port Unmanaged Gigabit Switches can also be utilized.
NOTE3: Chaining 4 and/or 8 port switches is NOT RECOMMENDED as it causes unnecessary extra hops that have been
found to cause performance and reliability problems.
