V-Series IrisX Panel - LAN Port Link Status Monitoring

EHX v. 13, V-Series IrisX panel v. 6.51 and above

In addition to the network redundancy feature (NWR), an IrisX panel will conduct regular link status monitoring on its LAN ports.

The link status of a port tells us whether the port is able to communicate bi-directionally, meaning it can both send and receive data. A link down would indicate that the ethernet cable is unplugged on either end, or otherwise defective. Link status monitoring is conducted by the network switch.

This monitoring happens continually, regardless of whether NWR is enabled on the matrix or the IrisX panel. The panel monitors the link status of LAN 1 and LAN 2 and if either LAN is detected as link status down, transmission will switch to the other port. NWR, if it is enabled, is paused temporarily until both LAN ports' link status is up.

The switch from inactive to active port typically occurs within one second (two seconds max).

Note:

Only one LAN port is active at any time. Therefore, it is not possible to daisy-chain panels when using EHX v.13 and above.

Active network status and history can be viewed in the EHX Monitoring screen.

Note:

If the panel is rebooted and only one network connection is detected (only one LAN has link status up), NWR will be disabled on the panel. When the panel connects to the matrix, if NWR is detected in the EHX configuration, NWR will be re-enabled on the panel.
