Aten KE8952 [17/17] Poe considerations

5.4. PoE Considerations

Power over Ethernet (PoE) allows an Ethernet switch to provide both data and electrical power to a

network device through a single cable. The KE8952 / KE9952 model features PoE functionality, so the

transmitter and receiver units can receive power and communications over a single cable.

To avoid overall consumption exceeding the network switch’s power capacity, it is recommended that a

switch with enough capacity for 15.4W of power to every port is used.

When selecting a suitable switch to work with the aten kvm over ip matrix system there are important values that need to be considered such as the switching capacity forwarding performance and igmp functionality please note the following basic recommendations 13
Configuring the network switch 14
Configuring the switch correctly will pass data more efficiently allowing a better stream across the network to each kvm over ip extender device the following settings will help optimize your network traffic through a switch 14
Igmp and other settings 14
Appendix 15
Example switch models and capacity calculations 15
Recommended network switches 15
When using a point to multipoint or multipoint to multipoint matrix mode installation it is essential to use a gigabit network switch with igmp functionality to experience the best performance this allows for more efficient throughput of bandwidth resources while supporting this type of setup the following table lists network switches that have passed aten s stress tests using the ke6900 series extenders our tests streamed content over a network with a resolution of 1920 x 1200 60hz 24bit color depth at 60 frames per second 15
When you are selecting a network switch suitable to be deployed with the kvm over ip matrix system the most important values to check in advance are switching capacity and forwarding rate 15

Problem monitors are flashing and mouse lags when streaming video i am using a cisco catalyst 2960 in my kvm over ip matrix system installation 10 kvm over ip transmitters and 18 kvm over ip receivers 16
Remedy ensure that igmp querier is enabled in addition to igmp snooping for multicast installations igmp querier is also crucial use the following commands in cisco 2960 cli mode 16
Show ip igmp snooping vlan 1 show ip igmp snooping vlan 1 16
Switch to switch bandwidth recommended bandwidth between switches depends on the total count of receivers in the installation 16
