e-Node LED Indicator Lights
Flashing Green 2x/second
Upon power up (with a known-good power supply and connected to Router-not PC), the on-board LED Flashes GREEN 2x/second until it can squires a DHCP address or and receive notification that if it is in STATIC IP mode, that the router has accepted the address. If the 2x/second does not shift to 1x/second within 90 seconds of a power-up, check you LAN connection, your crimps and your router. See the note below under Flashing Green 1x/second about AUTO-IP mode.
Flashing Green 1x/second
After successfully acquiring a DHCP address, the flashing GREEN indicator will normally slow to 1x second. However, if the e-Node cannot acquire a DHCP address usually within 90 seconds, it will automatically shift to a 1x/second status which indicates that it has shifted to AUTO-IP mode (with a 169.254.xxx.xxx address) and that it cannot obtain a valid IP address. Auto-IP Mode is used in a special case where a computer is set up to talk directly to an IP device (here the e-Node) without a router and both units are in static mode. This AUTO-IP Mode cannot be used for normal IP communication on a network or integrated with 3rd-party automation platforms. Check your router, LAN cabling, crimps and try again.
Flashing Yellow 1x/second
Upon power up (with a known-good power supply and connected to a Router-not a PC), if the e-Node was previously set to DHCP DISABLED (and rebooted), the e-Node LED indicator will start flashing YELLOW 1x/second if the system has accepted the STATIC IP address. However, if you see a Flashing Yellow 1x/second and your computer cannot discover the e-Node, it is likely that the IP Address or the e-Node's SUBNET MASK (previously set up with the e-Node) are not consistent with your current network. Specifically, your e-Node is set to a different subnet that is not "seen" by your computer. You will need to factory reset your e-Node in oder to proceed.
Please refer to this separate document for how to factory default your e-Node and place it back into DHCP mode so that it can be discovered again. Unless you backed up your e-Node previously, any programming will be lost in the process on the e-Node but not the significant programming entries made to connected ILC-xx0 devices which is not impacted by an e-Node factory default.
Solid Red (only on e-Node 4x00)
During power up (with a known-good power supply), if you see a blinking LED, that suggests that there has been damage to the ILC-xx0 (most likely during a firmware update) or that the load connected to the ILC-xx0 is shorted or is of such high current that it is tripping the powering DC power supply. Here, immediately remove the Load and check to see if the blinking LED goes to a sold GREEN or YELLOW color. If not, contact Converging Systems tech support.
