Device Status Code Series 500: Intermediate Network Problem

Description

If Keynote Red Alert is unsuccessful in opening a TCP connection to a secure device, and if ICMP has been selected, it attempts to ping the device. (Note: if ICMP is not selected, pinging the device is not attempted.) If the ping is unsuccessful, Keynote Red Alert will attempt to ping the Pingable Sibling Device selected. If this ping also fails, then Keynote Red Alert also attempts to ping the pre-selected Intermediate Network Gateways for this device. If all of these are unsuccessful, then Error Type 501 is reported to you.

In order for Keynote Red Alert to monitor for this error condition, you must select and input a "Pingable Sibling Device" by providing the IP address of a device on the same local network as the device to be monitored. This "sibling" device must be capable of responding to ping requests.


Summary

Error Type 501 means that, following an unsuccessful attempt to open a TCP connection to your device, individual attempts to ping your device, your Pingable Sibling Device, and your Intermediate Network Gateways were unsuccessful over all three of Keynote Red Alert's networks.



Error Type 502:
Device Unreachable; Intermediate Network Problem

Description

If Keynote Red Alert is unsuccessful in opening a TCP connection to a secure device, and if ICMP has been selected, it attempts to ping the device. (Note: if ICMP is not selected, pinging the device is not attempted.) If this ping is unsuccessful, then Keynote Red Alert attempts to ping the pre-selected Intermediate Network Gateways for this device. If these are unsuccessful, then Error Type 502 is reported to you.

Note: Keynote Red Alert will only return this error condition if you have not selected and input a "Pingable Sibling Device".


Summary

Error Type 502 means that, following an unsuccessful attempt to open a TCP connection to your device, attempts to ping your device and your Intermediate Network Gateways were unsuccessful over all three of Keynote Red Alert's networks.
